  • Accessibility Features

    Improving the accessibility features of browsers, other user agents, and operating systems makes every app and web site they render more accessible to people with disabilities. The Accessibility Features Community Group (AFCG) promotes the development of these accessibility features.

    People with disabilities will find similar features across browsers and operating systems that also work consistently for all provided content. For content creators, reliable built-in features will help to focus their accessibility efforts on addressing challenges unique to their content. These accessibility features can come in a variety of forms, such as:

    • Always-on features, such as page and app resizing
    • Toggles, such as always-visible focus indicators and high contrast modes
    • Settings, like preferred fonts and smallest text size
    • Fallback features, like automated captions and heading detection

    To promote the development of new accessibility features, AFCG will develop a list of recommended accessibility features. This list will include accessibility features already available, but also ideas for new accessibility features that can be shown to work through prototypes. To encourage the implementation of recommended accessibility features, AFCG will track which of these are supported in common browsers and operating systems.

    The Accessibility Features Community Group will not develop any normative specification. As such, there will not be any Essential Claims under the W3C Contributor License Agreement or Final Specification Agreement.

  • Accessible Online Learning

    Accessibility is often provided through accommodations. Schools are legally obligated to provide accommodations to enrolled students with identified disabilities, based on their needs—sign language interpreters in lectures for deaf students, digital copies of textbooks for students who are blind or have reading difficulties, extended time on exams for students who need more time due to cognitive or physical disabilities.

    With online learning, the obligations are less clear—for example, with MOOCs, where students around the world are taking courses but are not enrolled at the sponsoring school or organization. Also, accommodations are not well established—sign language interpreters and note takers are typically accommodations for the physical classroom. How does an organization ensure they are meeting obligations and giving online students the support they need participate fully and to be successful?

    Providers of online learning are best off delivering courses that are accessible out-of-the-box, without the need for special accommodations. And many of the features that provide an accessible experience for people with disabilities benefit all learners. For example, lecture transcripts are an excellent tool for study and review. However, without deliberate attention to the technologies, standards, and guidelines that comprise the Web Platform, accessibility may be difficult to achieve, and learners with disabilities may be left behind.

    The activities of the Accessible Online Learning W3C Community Group take place at the intersection of accessibility and online learning. We focus on reviewing current W3C resources and technologies to ensure the requirements for accessible online learning experiences are considered. We also identify areas where additional resources and technologies are needed to ensure full participation of people with disabilities in online learning experiences.

  • Age Labels Data Model

    The objective of the community group is to propose a technology-neutral data model for electronic content labels, i.e. age labels or content descriptors. The data model will include agreed categories and fields that may contain content-specific information. The proposal is planned to include a documentation, code snippet examples and probable queries to support implementing the data model in existing age classification contexts. The data model proposal and the documentation are planned to serve as guidelines for either existing players to implement the data model in their existing schemes (and thus providing users additional information in an interoperable way) or for new players that plan to label online content and thus reduce the risk of sunk costs.

  • Agriculture

    The initial mission of the Agriculture Community Group is to gather and categorise existing user scenarios, which use Web APIs and services, in the agriculture industry from around the world, and to serve as a portal which helps both web developers and agricultural stakeholders create smarter devices, Web applications & services, and to provide bird's eye view map of this domain which enables W3C and other SDOs to find overlaps and gaps of user scenarios and the Open Web Platform. We'll try to collect facts and knowledge from around the world through crowd-sourcing, while, at the same time, build a scaffold for it by quickly gathering key topics from Japanese agricultural stakeholders. Smart Platform Forum supports this early stages by connecting relevant stakeholders in Japan and organising face-to-face meetings if needed to proceed faster.

  • Augmented Reality

    The W3C Augmented Reality Community Group is an open forum for collaborative discussions about the intersection of Augmented Reality and the Web, or more simply the Augmented Web. This forum welcomes discussions about related standards, the standardisation process, related market developments and the broader social implications of this new generation of the web.

    We believe that the Augmented Web brings a unique perspective that pushes standards, APIs, hardware technologies and the broader web platform to the edge of their performance limits. The Augmented Web embraces the changes brought about by HTML5 and other related standards including Geolocation, DeviceOrientation, DeviceMotion, WebGL, Web Audio, Media Capture & Streams and WebRTC. The Augmented Web integrates all of these disparate technologies into an integrated new vision of the web.

    This group will not produce specifications.

    Instead it aims to build an integrated community voice that reaches out to all of the other relevant working groups and standards bodies to ensure that the Augmented Web perspective is clearly represented and considered. Our goal is to help ensure that the disparate standards and APIs being planned and implemented by these other groups can be seamlessly integrated into this new vision for the Augmented Web.

  • Automated Planning and Scheduling

    This group will discuss and advance automated planning and scheduling technologies, in particular planning domain definition languages. Using such languages, developers can define planning domains, these including types, predicates, actions, constraints, and preferences, and can define planning problems. Web technologies can be of use for designing new such languages, e.g., XML, JSON, Semantic Web technologies, and JavaScript. This group will develop a specification for a new planning domain definition language.

  • Automated WCAG Monitoring

    This group has been replaced by the ACT Rules Community Group.

    Creating (semi-)automated tests for WCAG is key to affordable, large scale research. The tests are designed in a way that they are useable by people with a variety of skills. The results too should be informative, not just to developers, but to website managers, policy makers and disability advocates and others. The objective of this community is to create and maintain tests that can be implemented in large scale monitoring tools for web accessibility. These tests will be either automated, or semi-automated, in which tools assist non-expert users to evaluate web accessibility. By comparing the test results with results from expert accessibility evaluators, we aim to track the accuracy of the tests we've developed. This allows for an iterative improvement and adjustment of the tests as web development practices change and evolve. It also provides the statistical bases on which large scale accessibility monitoring and benchmarking can be built. This group will not publish specifications.

  • Blockchain Naming System

    Explore blockchain based naming system used to name wallets and other objects stored in blockchains, such as non-fungible tokens. Blockchain elements are referred to by a long hexadecimal string. Just like IPv6 addresses, those are hard to remember. Creating human-friendly names that resolve to those strings was deemed an important step for the early adoption of blockchain technologies. Early blockchain developers did not develop DNS extensions for that purpose. They created entirely new alternative naming systems based on the particular blockchain they were working on. We are exploring all options for a unified web based solution to the problem.

  • Bridging GraphQL and RDF

    The aim of this group is to explore how GraphQL and RDF can be combined, and to what respect they can benefit each other. This group explores possible combinations of GraphQL and RDF. We identify and compare existing approaches that bridge these worlds, collect use cases and requirements for such approaches, and characterize corresponding application areas. This will produce deliverables that may serve as input for one or more possible future standardization efforts. Examples of application areas combining GraphQL and RDF are:
    • Read/Write Access (CRUD) to and from RDF data via GraphQL queries and/or interfaces
    • Validation of RDF graphs using GraphQL schemas
    • Mapping between GraphQL and RDF-based shape languages
    This group aims to produce the following deliverables:
    • An overview of all known approaches that combine GraphQL and RDF. This overview will include a brief description of each approach, the company/organization that has developed it, and links to the corresponding documentation.
    • An analysis of all known approaches that combine GraphQL and RDF. This analysis will include a categorization across one or more facets that will be identified.
    • A final report on suggestions/possibilities for standardization.

  • Browsers and Robotics

    This community group will discuss the applications of web browsers as the computer for controlling robots (robotics, in other words). And it will be also intended to feedback knowledge obtained from this discussion to standardization activity about Web of Things.

    What kinds of values are contained in using a Web browser not only in drawing graphical user interface but also in controlling and manipulating robots, and what kinds of difficulties and problems are there in that case? To search their answers may become the driving force of this activity.

    As an example, there may be the following questions in the discussion:

    • Is a case applying a Web browser as a simple controller of the robots which does not have UI such as screens or the pointing devices still meaningful? For example, connectivity with web services and interlocking operation between robots (Swarm Robotics via web) may be one of its values.
    • Is it possible to relate a graphical user interface of HTML to interactive and physical user interface of the robots? Is it meaningful? As an example, a relation between a physical push button and 'input' type="button" element in the HTML may deserve considering.
    • Are cases using relatively low-level interface used in many robots such as PWM of the motor, digital or analog signal interfaces, I2C, SPI, UART and GPIOs by the application on the web browsers meaningful?
    • Is real-time computing at the same level as RTOS feasible on the web browser-based general-purpose computing environments?

    An initial related activity is the Mozilla Factory Open Hardware Project.

    Furthermore, this group may publish specifications based on those knowledge such as webGPIO, webI2C API and so on.

  • Client and Server JavaScript APIs

    REST seven's rule was "Code on Demand," meaning the ability for the server to deliver code able to run on the client. Some, to use the same code everywhere, tried to do it with Java, .NET (ActiveX). Today, even Flash is fading out to let this place to JavaScript. HTML5 and offline support contributed in the creation of a bunch of APIs which only made sense on server-side in first place: File/FileSystem, Workers, Sockets, Storage/Session, Blob, ImageData. Most of those APIs, and even the already existing XMLHttpRequest (now in version 2) have been designed from the beginning to be usable via either synchronous or asynchronous APIs from the very early stages (synchronous is not blocking any more the user interface in browsers when used in workers). Now that the Server-Side JavaScript is rising again either in synchronous and asynchronous implementations, it is time, if we really want interoperable code/libraries/modules, to make those APIs taking into account the server-side context, and then on the other end, to push Server-Side JavaScript implementations to support them. CommonJS started a great project, it is now time to make its ambitions real.

  • Colloquial Web

    Status: This group closed due to lack of agreement on shared goals. The Colloquial Web group evaluates existing practices amongst core web technologies such as HTML, CSS, and JavaScript. It aims to give users and vendors clear reports on deployment and innovation for web applications. Example problem domains include continued use of deprecated constructs, the rise in external services for hosting solutions such as Google Web Fonts or MathJax, and comparing attitudes to RDFa and Microdata. The group researches the relationship between emerging social practices as regards existing technologies and their standards. A central research goal is to study and contribute to changing perceptions of conformance. Though broadly speaking the group has a bias towards empirical and descriptivist methods, it is not constrained to these approaches. It will not for example produce languages, but may create profiles of weighted technique matrices.

  • Colour blindness accessibility

    The aim of our project is to build new HTML5 specifications that can be used later by developers who wish to create more accessible websites for colour-blind people. The goal is that the specifications, that we are going to suggest, will one day become a standard of HTML5. According to WHO, 246 million people worldwide, whilst not being blind, suffer from moderate or severe visual impairment. This includes various forms of colour blindness and other visual deficiencies such as glaucoma and cataract. Just like everyone else, colour-blind people use the Internet for professional and private purposes. However, they often encounter accessibility problems. Our challenge is to improve their situation by providing easy-to-use HTML5 specifications to developers. To understand, define and bring solutions to colour-blind people who interact with web interfaces, we are going to conduct user tests with them based on the eye tracking technology. This will allow us to define a corpus of usability rules, according to the level of deficiency of the colour-blind persons. These rules will help us to develop solutions, validate them with other user tests and later develop HTML5 specifications that can be used in CSS. The challenge is not only helping developers with easy-to-use HTML5 markups, but also make them aware of the situation and together build a better Internet with more accessible websites. Feel free to join this group if you: * are suffering from colour-blindness * or have field experience developing accessibility solutions for the colour-blind or other visual impairment * or have experience working with a previous submission to the W3C.

  • Computational Legal Decision Support

    Open access of citizens to public information is fundamental for the effective functioning of (democratic) systems. Within the judicial branch this is often guarded both at local as well as at national level. The Computational Legal Decision Support community group (CLaDS) considers: the data sources for the system, i.e., documents describing proceedings of lawsuits; scalability of a prototype, i.e., how the data is to be meaningfully represented within the system; distinctions in regard to (semantic) judicial vocabularies; applications outside the legal domain. The group is in incipient phase and contributions are welcome. Our current focus is: a) the exploration of availability of formal litigations b) specification of the formal means of representation of lawsuit proceedings / legal knowledge. A extensive proposal is available at ssrn.com/abstract=2938453 .

  • Conversational Interfaces

    The mission of the Conversational Interfaces Community Group is to enable web developers to collaborate and share conversational experiences for a variety of domains. Most dialogue systems serve interactive experiences in their own domain specific language, causing a fragmented zoo of proprietary formats. For example, Google Home or Alexa do not share a common intermediate representation, which makes writing wide-spread content inaccessible to the mass audience. We study existing specs and design standards to harness proven techniques into common agreement. See the the Community Group's charter.

  • Decisions and Decision-Making

    The group will discuss and tentatively specify a format for representing decisions, i.e. decision information, so they can be used across diverse systems. Because of the great variety of applications and decision technologies, this format should focus on the generic, core components of decisions and decision-making information. Decisions are a source of information in themselves, i.e. each decision that is made is in itself a piece of information the may need to be stored, tracked, shared, combined and compared to other decisions. The same holds for information about the decision process. In particular, this group will discuss and study how Semantic Web technologies can facilitate the representation and sharing of decision information. Ultimately, the aim of the group is to study and develop technologies and methods to support better, rapid, and agile decision making.

  • Declarative Dynamic Extensions to HTML

    The mission of this group is to write the specification of a set of HTML declarative extensions that allow :

    • to write factorised HTML (with help of the handlebars template engine), perform some advanced dynamic behaviors (without javascript requirements),
    • and resolve some separation of concerns problems by adding a design layer between styles and the html document itself.
    This declarative design layer will provide, by external XML resources (initially called XML Design System Sheets) subset of handlebars templates to describe how user agent have to render the shadow dom of classical HTML elements.
    Moreover, the dynamic behaviours will use the data representation separations allowed by integrating model instance elements from XForms to HTML itself. To complete it, an extension will propose a new way to retrieve datas as a form control replacement based on the editor attribute, inspired from XForms specification.

    This group will produce reports after discussions, specification(s), and maybe a javascript experimental implementation. One or more of this skills and expertise are desired from participants : HTML, XML, Javascript, and an attention to the importance of the javascript unobstrusive recommendation (declarative HTML should be full functionnal , security reasons, stability...).

  • Declarative Linked Data Apps

    The mission of this group is to produce a specification that describes how Web and Linked Data applications can be built using declarative technologies only, minimizing the need for source code. Current software development models involve writing source code (mostly in imperative languages) and building programs from it. Source code is prone to bugs, and managing it requires developers. The declarative approach is instead to push as much application logic from source code to data, so that the application can be managed and reused as data itself, while the software become generic and application-independent. This approach is related to functional languages and to processing pipelines. The generic software works as a processor: it takes the incoming request and the declarative application description and runs it through a pipeline, first retrieving the state of the requested resource (or changing it) and then rendering it into the requested format, such as a Web page. This is similar to an XSLT processor transforming XML documents. Graphity is a production-level platform for declarative end-user Linked Data applications with an RDF triplestore backend. It processes ontologies describing application structure, which seemlesly combine multiple declarative technolgies: URI templates, SPIN SPARQL templates, XSLT stylesheets (both server- and client-side), and RDF/POST encoding. Please join this group if you're interested in any practical or theoretical aspects of Linked Data, declarative technologies, or Graphity software.

  • Development Linked Data

    Data is commonly considered as a new kind of fuel powering economical, cultural and societal changes. From e-governance to smart cities, many examples can be found to argue for the value of open and connected data. By turning the Web into a data publishing platform Linked Data is a key enabling technology for this. It has yet to be kept in mind that as of 2012 65% of the world does not have access to the Web and are thus deprived from Linked Data. Furthermore is this population sorely in need for the changes data-driven societies benefit from. This community group is there to discuss some important questions such as: * How can development related data be published as Linked Data? * What kind of data is out there and what is relevant to drive societal changes in underprivileged countries? * How can those without Web access can consume open data set published as Linked Open Data? * How can the Linked Data principles be revised to be applicable in Web-less contexts?

  • Digital Publication

    This group is closed; For discussion on this topic, please refer to the Digital Publishing Interest Group: http://www.w3.org/dpub/IG/ The growth of the tablet and eReader market, and changes in scholarly publishing, have shown the accelerating impact of the Open Web Platform on digital publishing. For example, ePUB 3.0 no longer subsets W3C standards like HTML5, CSS, SVG, MathML, and Javascript APIs, but uses them in full. It also extends them to cover the various needs of digital publishing. These extensions, and continuing fragmentation among devices, formats, publishers, and distribution networks, suggest an opportunity for W3C to address publishing industry use cases, from novels and prose through to scientific and scholarly publishing, medical and legal publishing, interactive children's books, magazines and more. The initial aim of the Digital Publication Community Group will be to determine if W3C should invest more heavily in digital publication, and if so, what role it should play. The CG will establish and strengthen active liaisons with existing digital publishing fora, such as the International Digital Publishing Forum (IDPF) which oversees the ePUB specification, as well as digital publishers and distributors of all types. The Digital Publication Community Group will also explore the idea of one or more workshop on the topic, and provide a forum for open discussions on the future of digital publishing, specifically: * reducing market fragmentation * describing traditional and emerging publishing workflows, from the technology perspective * creating scenarios and requirements to drive future standardization in W3C Working Groups, including layout, internationalization, security, accessibility, content protection, metadata, and vocabularies. This group will not publish Specifications.

  • Digital ssset standard

    The primary mission of the community group is to bring together (top companies, universities, and teams involved in digital finance technology in various industries) and frontier technology in digital finance to push forward the development to digital asset standardization.

    What is a digital asset? A digital asset is data with unique identity attributes that are binary coded, owned, or controlled by a company or individual. The data has various manifestations, including text content, images, multimedia, Computer programs, etc. Generally speaking, digital assets include websites and their content, domain names, application software, codes, electronic documents, image content, media content, electronic money, emails, game accounts, other accounts & their content, social network accounts & their relationships and cloud service accounts & their data, etc.

    The digital asset on the blockchain owns all the general attributes of digital assets above, it also has other characteristics: the computer programs registered on blockchain ledger or distributed ledger, as well as the virtual assets existed in the form of bit structure, can be programmed. The exchange of assets is essentially the exchange of code. The digital assets on the blockchain can achieve complete disintermediation of autonomous and autonomous point-to-point transactions without the need for third-party manual intervention. Once the asset is issued on the blockchain, the subsequent circulation link can be independent of the issuer’s system. As the asset circulation is changed from single-center control to socialized communication, any channel with resources can become a catalyst for asset circulation, which greatly improve the efficiency of digital asset circulation, and truly achieve the effect of "multi-party issuance and free circulation."

    To welcome the era of asset digitization, the group is formed to technically communicate and cooperate with other members, and to develop a broader market together. The problems that we are trying to solve in this group are:

    1. Digital asset operation, trading, development, and supervision standardization;
    2. Formation of industry alliances and specification of industry standards;
    3. Universal education of digital assets

    The group aims to support pioneer companies that explore digital assets, encourage communication and cooperation. We are expecting deliverables such as published reports and a service platform on this basis.

  • Distributed Trace Context

    This group has completed its work. People interested in this topic should join the Distributed Tracing Working Group.

    The mission of this group was to define the standard for distributed trace context propagation. Distributed trace context is used to enable monitoring and diagnostics scenarios in micro-services environment. It consists of request identifiers and key properties that needs to be propagated from one micro-service to another. These identifiers and properties are used to analyze an end-to-end distributed traces.

    The group primary objective was to publish a specification for the protocols to use for distributed trace context propagation. Protocol includes wire format and recommended scenarios to use these protocols in applications, web servers, libraries, and platforms. The group also targetted to produce reference implementation for some languages.

    Standardized and universally used trace context propagation protocols enable monitoring and diagnostics scenarios that are hard to achieve otherwise. Authors of libraries, web servers, and application performance management (APM) vendors interested to improve micro-services monitoring and diagnostics story were encouraged to participate in this group.

  • Distributed User Interfaces

    Current technology and ICT models generate configurations where the same user interface can be offered through different interactions. These new technological ecosystems appear as a result of the existence of many heterogeneous devices and interaction mechanisms. Consequently, new conditions and possibilities arise which not only affects the distribution of the user interfaces but also the distribution of the involved users’ interactions. Thus, we move the focus from addressing the distribution of user interfaces to the distribution of the users’ interactions which poses new challenges that deserve to be explored. In this context Web engineering appears as a fundamental research field since it helps to develop device-independent Web applications with user interfaces capable of being distributed and accessed through different interaction modes. This fact makes Web environments to be especially interesting within the scope of this community group. The main goal is to join people working on Distributed Interactions and share their knowledge in aspects related to new interaction paradigms and the way we can manage them in a distributed setting on the World Wide Web.

  • Electrophysiology of Vision Markup Language

    Exchange of electrophysiological data for post-processing including in clinical trials is gaining increasing importance. Although manufacturers of electrophysiological devices usually provide means for exporting data, these are often restricted to either proprietary or ASCII-based formats which do not provide access to raw data or protocol details. With the need for central reading in multi-centre trials this becomes a major problem. The reading process usually requires all details of a measurement, to allow for properly monitoring compliance with study protocols. Standards for exchanging data have already been approved for other applications of electrmophysiology including EEG or ECG. However, these standards are usually focused on their specific field of application. Common standards are also available, like GDF (General Data Format for Biosignals), EDF (European Data Format), or HL7 and DICOM; however, these standards either do not match the specific requirements of ophthalmic electrophysiology or the efforts to adapt them are very high. Therefore we are proposing an open standard for the exchange of data for electrophysiology of vision based on the Extensible Markup Language (XML).

  • Experience API (xAPI) Vocabulary & Semantic Interoperability

    Currently Experience API (xAPI) mostly focuses on providing “structural” interoperability via JavaScript Object Notation Language (JSON). Structural interoperability defines the syntax of the data exchange and ensures the data exchanged between systems can be interpreted at the data field level. In comparison, semantic interoperability leverages the structural interoperability of the data exchange, but provides a vocabulary so other systems and consumers can also interpret the data. Analytics produced by xAPI statements would benefit from more consistent and semantic approaches to describing domain-specific verbs. The xAPI specification recommends implementers to adopt community-defined vocabularies, but the only current guidance is to provide very basic, human-readable identifier metadata (e.g., literal string name(display), description). The main objective of the Vocabulary and Semantic Interoperability Working Group (WG) is to research machine-readable, semantic technologies (e.g., RDF, JSON-LD) in order to produce guidance for Communities of Practice (CoPs) on creating, publishing, or managing controlled vocabulary datasets (e.g., verbs).

  • Exploration of Semantic Data

    Semantic data is available widely and semantic data exploration is becoming a key activity in a range of application domains, such as government organisations, education, life science, cultural heritage, and media. Several novel interfaces and interaction means for exploration of semantic data are being proposed, for example exploratory search systems, semantic data browsers, ontology/content visualisation environments and semantic wikis. Although on the rise, the current solutions are still maturing and need to take into account human factors to make exploration intuitive or employ necessary computational models to aid the intuitiveness and improve the effectiveness of exploration tasks. Lessons also can be learned from the commonalities and differences in exploration requirements between different domains. Hence, greater benefits can be achieved by bringing together expertise from different communities, including HCI, Semantic Web, and personalisation with the potential application domain demands. This group is an effort to bring these community together to benefit from the mutual experiences in solving some new and exciting problems. This group will not publish specifications.

  • Exposing and Linking Cultural Heritage data

    The wealth of data about cultural heritage collections held within archives world-wide is of great interest for humanities research and education activities. Yet this data is too often hard to find, created in isolated silos and poorly documented. Large projects such as RES (https://bbcarchdev.github.io/res/) , HuNI (https://huni.net.au), Europeana (http://www.europeana.eu) and CLARIAH (http://www.clariah.nl/) express a clear need for making that data easier to find, link and consume. The mission of this community group is to discuss which standards are needed to facilitate this process. The aim is to produce recommendations for cultural heritage data exposure using the work of RES, HuNI, Europeana and CLARIAH as a starting point.

  • Federated Commerce

    Decentralized e-commerce and storefront apps will more easily share and syndicate their products rather than relying on single and proprietary APIs from hosts to operate a storefront. By structuring portable commerce data stores, protocols, and semantics, this group seeks to enable marketplaces to be built more eaily and made more easily discoverable.

    This group's efforts will complement existing activities such as Web Payments, Linked Data, and DID, to deliver a search, browse, configure, checkout, and payment workflow for physical and digital products with mostly existing web technologies.

    At a higher-level, it would be potentially beneficial to include support for an aggregate query language, (such as SPARQL) to enable applications to query a known network of compatible applications for product information to better support web resource-to-web resource indexing and listing of products, increasing visibility without the need for central search engines. This would potentially utilize HTTP methods to register product catalogs in other web apps or request product catalogs from other web apps, enabling products to be purchased outside of the scope of the original commerce site, creating an aggregate marketing power across the web rather than depending on singular, monolithic e-commerce platforms.

  • Federated Timesheets

    Each project has a timesheet system to track billable hours. Workers often spend time manually filling in this data multiple times. Instead, we’ll make time tracker apps (locally or on a self-hosted server) expose machine-readable timesheet data through a query endpoint (reader pull) or through a webhook (writer push). Timesheet data is relatively simple in terms of data format, data replication only flows in one direction, and there are not too many identities involved in the authentication / authorization of the data source connections. This simplicity makes the “Federated Timesheets” project an ideal case study for Federated Bookkeeping in general. We want to show case how our vision of Federated Bookkeeping can make internet users “connected but sovereign”.

  • Follow Public Money all the Way Vocabulary

    Recently, a series of important, and often overlapping, initiatives has emerged in the domains of opening and linking government data. A part of this data is related to economic data such as public budgets and spending, calls for tenders, business registries, prices and financial statements (refer for example to publicspending.net, opencorporates.com,openspending.org, open-contracting.org, sunlightfoundation.com/clearspending, internationalbudget.org). The challenge is to find ways to ask useful and real-life questions in these datasets with minimum effort. We address this issue by proposing a vocabulary to interlink open data with regards to public budgeting and spending, e-procurement and business information. The proposed Follow Public Money All the Way Vocabulary is based on the efforts of several Semantic Web communities (e.g. Organization Ontology, Registered Organization Vocabulary and Public Contracts Ontology) and will try to incorporate existing practices, principles and standards on the related domains (e.g. IATI standard on aid, open contracting global principles and procurement open data guidelines). The potential usages of the vocabulary ranges from crowdsourced monitoring and risk assessment of public finance to real-time integration of public budget, tendering and spending information in Business Intelligence systems for stimulating more efficient resource allocation.

  • Getting Math onto Web Pages

    We invite you to visit the main site for this Community Group.

    There are many technical issues in presenting mathematics in today's Open Web Platform, which has led to the poor access to Mathematics in Web Pages. This is in spite of the existing de jure or de facto standards for authoring mathematics, like MathML, LaTeX, or asciimath, which have been around for a very long time and are widely used by the mathematical and technical communities.

    While MathML was supposed to solve the problem of rendering mathematics on the web it lacks in both implementations and general interest from browser vendors. However, in the past decade, many math rendering tools have been pushing math on the web forward using HTML/CSS and SVG.

    One of the identified issues is that, while browser manufacturers have continually improved and extended their HTML and CSS layout engines, the approaches to render mathematics have not been able to align with these improvements. In fact, the current approaches to math layout could be considered to be largely disjoint from the other technologies of OWP. Another key issue, is that exposing (and thus leveraging) semantic information of mathematical and scientific content on the web needs to move towards modern practices and standards instead of being limited to a single solution (MathML). Such information is critical for accessibility, machine-readability, and re-use of mathematical content.

    This Community Group intends to look at the problems of math on the web in a very bottom-up manner. Experts in this group should identify how the core OWP layout engines, centered around HTML, SVG, and CSS, can be re-used for the purpose of mathematical layout by mapping mathematical entities on top of these, thereby ensuring a much more efficient result, and making use of current and future OWP optimization possibilities. Similarly, experts should work to identify best practices for semantics from the point of view of today's successful solutions.

    This work should also reveal where the shortcomings are, from the mathematical layout point of view, in the details of these OWP technologies, and propose improvements and possible additions to these, with the ultimate goal of reaching out to the responsible W3C Working Groups to make these changes. This work may also reveal new technology areas that should be specified and standardized on their own right, for example in the area of Web Accessibility.

    The ultimate goal is to pave the way for a standard, highly optimized implementation architecture, on top of which mathematical syntaxes, like LaTeX or MathML, may be mapped to provide an efficient display of mathematical formulae. Note that, although this community group will concentrate on mathematics, many other areas, e.g., science and engineering, will benefit from (and factor into) the approach and from the core architecture.

  • Haptic Interaction on the Web

    Haptic feedback can offer significant benefits in terms of accessibility and usability of touch-based interfaces. Many mobile devices, such as smart phones and tablets, incorporate built in vibration feedback.

  • HFVRP

    This mission of this group is to help re-establish platform interoperability between descendants of the original "High Fidelity Virtual Reality Platform" (HFVRP) open source project.

    The group will initially host discussions and coordinate volunteer research efforts in order to identify relevant areas of common ground across HFVRP projects.

    For example, it was once possible to use the "interface" client from one platform to connect to a "domain server" hosted on a similar, but different platform. As these projects have continued to evolve, the once-shared protocol version (for example) between them has fallen out of sync, inadvertently breaking the possibility of cross-connections.

    By gathering together common interest across multiple projects, this group hopes to then help collectively estimate efforts and help champion neutral sub-projects that can restore specific compatibilities.

    It is suggested that neutral community sub-projects emerging from this group adopt the permissive Lesser GNU Public License (LGPL) open source license. LGPL currently seems to align best with the mission at hand and for these reasons:

    • interoperability across diverse projects is likely to be an ongoing, multi-platform, community-driven effort -- adopting LGPL for these components can help ensure the collective community effort remains transparent and improvable across the entire project space
    • as degrees of interoperability are restored LGPL dependencies can be version-managed and upgraded per each projects typical dependency update schedules
    • LGPL is already an approved dependency license across HFVRP projects (ie: all known platforms critically depend on Qt by way of the LGPL) -- by not introducing a new license for these shared efforts, existing open source project audits can remain intact

    This effort will hopefully span across diverse project politics, technical minds, and social circles which can come together and approach compatibility as a shared effort.

    All platforms forked from the original HFVRP code base are welcome to join forces this way and in particular contributing developers, community members, and any others interested in helping broaden platform interoperability.

    Some of the low-level technology skills likely needed to restore interoperability are:

    • familiarity with HFVRP networking protocols and versioning
    • "HFM" internal model formats and corresponding C++ structures
    • overall "Oven" asset baking tool and filesystem layouts
    • Baked asset structures (materials.json, ktx, modded FBX format w/draco compression, etc.)
    • Entities "models.json.gz" world persistence format and "domain server" archive formats
    • "Avatar.fst" and internal blendshape "de facto" standards
    • "Interface" client, "domain server," and "assignment client" JSON configuration formats
    • (as common sub-projects emerge) help setting up multi-project Continuous Integration systems

    We think it will be easiest for volunteers in cases where interested projects have remained open source, but all HFVRP projects (including closed source ones) are welcome to join and suggest specific layers or features they would nonetheless be interested in seeing reemerged as a common open source dependency.

    This group will not publish Specifications.

  • HTTPS in Local Network

    The HTTPS in Local Network Community Group (CG) explores the manner of secure communication between browsers and server-capable devices in local network such as set-top boxes, network attached storages, etc. We propose that this Community Group clarify requirements for browsers and devices in issuing valid certificates and establishment of HTTPS and WebSocket connections over TLS and incubate relevant specifications of APIs and/or network protocols. This work has four primary purposes:
    • Improve security and privacy of communication between browsers and server-capable devices.
    • Enable web applications in secure contexts to communicate with server-capable devices in local network via XMLHttpRequest, Fetch API, and WebSocket.
    • Enable service discovery mechanisms to advertise existence of TLS-enabled server-capable devices.
    • Encourage adoption and implementation of the specification by browser vendors and device manufacturers.
    Given wider support and adequate stability, we plan to migrate the proposals generated in this Community Group to an appropriate standards track, for example the IETF Standards Track or a W3C Working Group, for further contributions and formal standardization.

  • Human Services

    The goals of the Community Group on Human Service Data are to:

    1. Create an ongoing conversation space around world data standards in the human service sector, involving stakeholders from multiple perspectives including:
      1. government human service agencies, for-profit companies, and NGOs;
      2. diverse substantive areas, such as welfare benefits eligibility, health interfaces, information and referral services, homelessness, substance abuse, child welfare, aging and disability resources, juvenile justice, etc.;
      3. diverse stakeholder purposes including exchange of data for operational purposes and collection of data for performance measurement, evaluation and policy research.
    2. Facilitate the development, improvement and convergence of human service data standards, vocabularies, ontologies, and domain models by:
      1. Cataloging human services ontologies worldwide, and creating a Linked Open Data directory of the ontologies. The directory should contain metadata, such as audience, jurisdiction, potential ontology improvements, related ontologies, and other notes. See Github site linked off the group page for group artifacts.
      2. Fostering wider recognition of existing efforts and artifacts
      3. Analyzing the strengths, limitations, and areas of overlap, agreement and divergence of existing efforts and artifacts
      4. Identifying areas where standards do not yet exist, but are needed
      5. Convening working groups of diverse composition to develop and improve standards
    3. Promote the adoption of human services standards

    Scope of Work:

    The boundary of the Community Group’s work is the set of substantive areas which are recognized in the United States and/or internationally as falling within the human service sector. This includes but is not limited to information and referral services, income support and other welfare benefits, employment training, homelessness, substance abuse, mental health, child welfare, juvenile justice, domestic violence, and senior services.

    The borders between the human service sector on the one hand and the health, education and justice sectors on the other hand are not firmly defined. The community group will be open to working on any area that is related to the human services and is not entirely within the boundaries of the health, education or justice sectors.

  • Instant Syndicating Standards

    Note: Work has moved to the Read Write Web Community Group. ISS/IM is an open set of standards that empowers individuals to discover and syndicate information through the help of their own personal social network. As of today, there is no existing technology that allows individuals to share information in a bottom-up manner on a global scale. ISS/IM is a proposal to create just that: a distributed worldwide recommender system perfectly tuned to output a very personalized stream of information for each individual, where information flows from the personal social network towards the whole wide world.

  • Inter-Platform Validation for Confidential Computing

    The mission of this group is to discuss and ultimately formalise a communication framework to enable mutual validation and attestation of workloads performed in distinct confidential computing environments. The goal is to empower developers to leverage seamlessly the developing ecosystem of confidential computing solutions agnostically across vendors and opensource. It is not the motivation of this group to publish reports but rather work on testable deliveries, example implementation, user-stories. This group may publish Specifications. Individuals and organisations with intimate knowledge of the confidential computing world and adjacent topics such as cryptography and privacy are most welcome to participate.

  • Interactive APIs

    The goal of the Interactive API Community Group is to develop an HTML annotation approach - similar in spirit and style to micro-formats - to equip a piece of UI (e.g., parts of a web page, such as a table or a sub-area) with a programmable interface (API). That is, the goal is to equip pieces of UI with dynamic and programmable behavior, so as to foster reuse on the Web and enable a set of web-based integration scenarios that are currently more the result of hacking and less of principled software development: programmatically operating UIs, extracting data, extracting application logic, and cloning pieces of UIs. The intuition is to design a new type of interpreted API, the so-called interactive API (iAPI), that enables (i) programmatic access to UIs and (ii) interactive, live programming. The purpose of iAPIs is not merely to provide access to static content inside a web page, but rather to bridge between the Surface Web (the UIs) and the Deep Web (common web APIs and web services). The concrete results this Group aims to produce are therefore: - An HTML annotation format for the specification of iAPIs; - An set of programming abstractions and code libraries for iAPI programming; and - A set of supporting browser extensions for iAPI parsing and instantiation. The final vision is twofold: first, to found a programming paradigm based on the reuse of UIs, i.e., UI-oriented computing; second, to enable interactive, live reuse to non-programmers directly inside the web browser.

  • MathML Refresh

    MathML first became a W3C recommendation in 1998. It has wide support in the publishing industry and with assistive technology. MathML has had several updates, but is showing its age and needs to be updated. This group will focus on changes to the MathML 3 recommendation so that it better aligns with the current web environment, eases the burden on browser implementations, and increases support for assistive technology. The group will propose a new revision for MathML, potentially with profiles for browsers, publishers, and other subgroups such as authors or online tests. The group will also develop tests so that authors/publishers can be confident that what they see as an author is what the user will see as a reader when the same font is used. Participation is encouraged if you are in involved in publishing, authoring, or rendering math. The group strongly encourages the participation of those involved with browser implementations, recommendations, and APIs that potentially affect the rendering of math.

  • Network-Friendly App and WebApp Best Practices

    Welcome to the W3C Community Group for Network Friendly applications! In this group, we are looking for contributions to help us reach the widest possible consensus in a critical area facing the mobile industry. Smartphones and smartphone applications have established themselves as a major success story in the industry over the past few years. As the number of smartphones and smartphone applications has increased the industry has learnt much on how to create efficient applications for smartphones. The GSMA has created a set of guidelines for application developers that will enable improvements across a number of areas including application connectivity, power consumption, network reliability and security. By following these guidelines - Developers will be better equipped to create fit-for-purpose apps - Users will experience more responsive and reliable apps and improved battery life - Mobile operators will see a reduced strain on their networks For a copy of these guidelines check out http://www.gsma.com/go/download/file=gsmasmarterappsforsmarterphones0112v.0.14.pdf GSMA intends to issue an update of the above document by end of 2012. As such, it has compiled a list of items for inclusion in the update after consulting GSMA’s members; they include network operators and device manufactures. To ensure the new update will have the widest possible support by all communities across the industry, we have created a Community Group called ‘network friendly Developer guidelines’ under auspices of W3C. The new CG is formed with a view to engage other developers or interested parties and reach a consensus as what needs to be added beyond what has already been proposed by GSMA. The proposed items for inclusion are embedded in this document. Check out http://www.w3.org/community/networkfriendly/wiki/images/b/be/Proposed_items_for_inclusion_in_the_update.doc to download the current suggestions as approved by GSMA. As the update will be released by end of 2012, all changes should be agreed in time before the actual work of writing and editing the document starts in earnest and no later than 1st September 2012. That means the outcome of activities in the CG would be a list of items for inclusion beyond what has already been proposed by GSMA. The outcome would be considered by GSMA for inclusion when updating the document. In Brief, the goal and milestones to bear in mind are as follows. Goal To produce a set of items for inclusion in the updated document beyond what has already been suggested (see the enclosed document) Key milestones 19th April to 10th August 2012 to discuss the base document and the proposed updates and reach consensus in the CG on any additional proposals 11th August to 18th August is the cooling off period to take on board last minute suggestions and final touches 19th August to 31st August, GSMA will consider the final input from CG prior to commencing work on the update in September As a rule of thumb, the entire process would be transparent and inclusive to reach agreement by discussion. In the unlikely event of not reaching consensus on burning issues, the (yet to be named) CG chair would make the final decision only as a last resort. You are invited to actively engage with the process to make the resulting document much better than its debut version. We welcome views and contribution with an open mind.

  • Networked Data

    The recent years have shown the need to deal with networked data in large-scale, distributed settings. Not only must the systems be scalable, elastic and performant, but also address *ability (usability, manageability, etc.). One key component is doing it the webby way. The Web is the leading concrete exemplar of RESTful design, being the result of posthumous analysis of what was already working with URIs, HTTP and HTML for a system of interlinked documents. Unfortunately the machine equivalent of HTML is still emerging. LinkedData has achieved some powerful results; automated navigation by querying the Linked Open Data cloud shows some of the potential. However many systems also need to evolve and be evolved. This can be expressed as 'service capability' and also needs to be supported with consistency. This should aim to eliminate the wide range of non-interoperable approaches muddling the current landscape of REST APIs through exploiting hypermedia concepts. The Networked Data Community Group aims to provide a forum for collecting use cases including but not limited to the fields of science data (such as biology, astronomy, etc.), economics data (financial markets, etc.), health care, configuration and systems management, Green IT, and smart infrastructures (cities, etc.). Based on the collection of use cases the CG will derive requirements and write up best practices for dealing with the dynamics of the data.

  • Offline URL

    Currently a file URL (file:///) is the defined way to access a local file in a browser. For various reasons (some outdated) this is not a preferred mechanism. There have been several unsuccessful attempts to create an alternative, but these were focused on application-type functionality and not content. For content originally created in HTML, it makes the most sense to offer a mechanism to store the file locally in the same format. While, if this is desired, that process is the responsibility of the site, the browser functionality for it must be a recognized standard. This initiative is focused on creating an offline url standard to access HTML files and containers stored locally in a compressed format, but otherwise behave as close to possible as an online site accessed via http. The charter for this group is currently under development on GitHub. If you are interested please follow and contribute there.

  • Open and Transparent W3C

    Although the World Wide Web (WWW) is an open and free information system, participation in the member-based World Wide Web Consortium (W3C) typically requires paying a membership fee to participate in the Consortium's standards setting groups. As such, the W3C is often criticized as a closed organization by those that are not members of the Consortium. This group aspires to help provide non Members with simple mechanisms to provide feedback to the Consortium (the Consortium's Members and the Consortium's Staff) on topics such as (but not limited to): areas where new Web standards are needed (e.g. to help address some interoperability pain point), Consortium priorities, the evolution of the Web, aligning Consortium's activities with the Web, collaboration with other organizations, etc. Anyone - including non-Members - is welcome and encouraged to join this group. Participants include technical contributors to Web standards, Web standards Editors and group Chairs. The group also includes participants from the Consortium's "Advisory Committee" and at least one member of the Consortium's elected Advisory Board. Additionally, the group welcomes members of the Consortium's staff. If someone wants to communicate with this group but does not want to formally join it, that's OK; just send an email to the group's mail list: public-openw3c@w3.org (see for the list archive and RSS feed information).

  • Open Annotation

    The purpose of the Open Annotation Community Group is to work towards a common, RDF-based, specification for annotating digital resources. The effort will start by working towards a reconciliation of two proposals that have emerged over the past two years: the Annotation Ontology [1] and the Open Annotation Model [2]. Initially, editors of these proposals will closely collaborate to devise a common draft specification that addresses requirements and use cases that were identified in the course of their respective efforts. The goal is to make this draft available for public feedback and experimentation in the second quarter of 2012. The final deliverable of the Open Annotation Community Group will be a specification, published under an appropriate open license, that is informed by the existing proposals, the common draft specification, and the community feedback.

    The Open Data Directory lists products, services and research projects that leverage Linked Data. Currently, the Directory serves as an aggregator of use cases and web sites using Linked Data and is expected to evolve over time in response user requirements. The Directory is a community service project to foster ease-of-use and awareness of Open Data on the Web. The Directory has an easy to use Web interface enabling users to list: - Organization name - Contact name - Product(s) - Service(s) - Projects & Use Cases The Open Data Directory periodically gathers Linked Data from designated sites and compiles it into a summarized view of the community. It is a purely Linked Data application and not another "walled garden." Organizations are responsible for publishing their own Linked Data for the Directory to consume. The Open Data Directory includes some basic visualizations that are expected to expand over time. The site is built on open Web standards and an Open Source data platform hosted on the cloud. All of the data is freely available for download as RDF. The Open Data Directory is open and does not require W3C affiliation.

  • Open Government

    This group's mission is to discuss and prepare data and API specifications relating to open government information, which may include: * people, such as legislators * organizations, such as legislatures or committees * people's positions within organizations * areas, such as electoral districts * events, such as elections * documents, such as bills or agendas * speeches, such as those given by legislators in legislatures * votes The group will base its work on existing standards as much as possible, and re-use existing terms (classes and properties) wherever appropriate. The group may define various serializations of the specifications, including but not limited to RDF and JSON. The group will seek consensus around, and support for, these specifications which may then be brought to an appropriate Working Group to advance a specification from draft to standard. The group will coordinate as appropriate with the Web Schemas Task Force of the Semantic Web Interest Group and other relevant groups within the W3C.

  • Open knowledge-driven service-oriented system architectures and APIs (KiSS)

    W3C provide a great variety of standards that can be used to build applications that use the Internet as a platform for communication and integration. The open Knowledge-driven Service-oriented System architectures and APIs (KiSS) community group is created for sharing, elaborating and evolving knowledge-driven approaches for system integration. The KiSS community group takes service-oriented architecture as a main paradigm for application creation. However, it is not enough to say that there is a set of some services that can be integrated according to the application needs. The integration is facilitated with semantic descriptions of the services. Furthermore, the special support components are required at system run time in order to allow dynamic composition of the services accordingly semantic representation of adjusted or new system goals. Thus, the community aims to categorise different possible architectures to allow knowledge-driven approach for system integration; it provides reference architectures that also point out possible technologies for the solution implementation. The community targets different application domains and industries in order to benefit from cross-domain vision on development of knowledge-driven systems. The abbreviation of the community group highlights the integrative nature of the group (small i among K (knowledge), S (service) and S (system)). The group is managed by 6 re-electable chairs. The roles and responsibilities of the chairs go as follows:
    • General chair: Ideologist. Overall synchronization between different pillars of the KiSS. PR with other groups and external stakeholders. Member attraction, community group development.
    • Chair for integration: Integration technologies, web service composition.
    • Chair for knowledge: Knowledge representation and reasoning standards and methodologies.
    • Chair for devices: Embedded devices, their adoption for KiSS.
    • Chair for services: Web services, standards, methodologies for service definition.
    • Chair for application domains: KiSS in different application domains. Cross-domain learning and development. Benchmarking.

  • Open Linked Education

    As a burgeoning and emerging area, open linked data for education is currently experiencing momentum across several initiatives and organisations including Open Education, LinkedUp, LinkedUniversities or LinkedEducation., and the Open Knowledge Foundation, to name just a few. We believe that we are now at a time when these efforts should converge, with this group representing a focus point for the community to collect, capture and adopt the practices that are going to be the foundation of the web of educational data. We therefore set the following set of goals for this group: 1. To collect from existing initiatives the practices currently used to share education-related data on the web. This includes the vocabularies that are employed as well as the ways in which common aspects of the data are being modelled with these vocabularies (e.g.course catalogues, resources, university facilities, research results). Further statistical analysis can provide sound guidance on vocabulary usage within the educational Web of data. 2. To identify common, best practices amongst those and document them (including concrete examples). 3. To facilitate the adoption of these common best practices, through direct interaction with community stakeholders, as well as through showing the benefits of the reuse of data modelling practices in application developments. While this has some similarities with the idea of “creating an ontology of education”, it is not what we are aiming to achieve. Education is very broad, and our goal is therefore rather to provide common “patterns” that use existing vocabularies for the representation of common education-related data. We do expect this to create resources of interest whenever our efforts will contribute to filling a gap, and to refer to other of such resources (such as LRMI for learning resources) in other cases. This group will not publish specifications.

  • Performing Arts Information Representation

    Performing Arts Information Representation (PAIR) is a community group dedicated to advancing the use of shared conceptual models for better data interoperability in the performing arts domain. This domain stands to gain tremendous benefit from using Semantic Web technologies as it relies on the interoperability of information across many fields such as event publishing and discovery, digital archiving, and research (to name a few). The group’s mission is to support the development and use of semantic vocabularies and common representational frameworks to ensure the meaningful sharing and aggregation of information related to the performing arts. This Community Group provides a forum for the exchange of ideas and experiences, scenarios and requirements while bringing together key stakeholders. The group will act as an advocate for representational standardization in the performing arts sector. PAIR will strive to develop mutually beneficial collaborations with groups and organizations that are actively working on relevant standards and/or implementations. In particular, the group will work to develop extensions to existing representational standards such as Schema.org and Wikidata so that Performing Arts information can be better understood by search engines and other web applications. While designing, maintaining and revising vocabularies and foundational specifications for the performing arts, the group will make efforts to involve the performing arts community at large through solicitation of requests, comments and suggestions from non PAIR members. This may take the form of symposiums, workshops, events or community curated open resources.

  • Philosophy of the Web

    Many philosophical issues have arisen in the technical design of Web standards over the years. Philosophical conundrums sometimes seem out of context in the light of seemingly more pressing technical problems. Yet, the very fact that these philosophical problems are constantly raised indicates that they are not easily dispensed with, but should instead be the focus of serious and ongoing long-term discussions. This is why this CG aims at undertaking such discussions, even outsourcing them to alleviate the task of other groups. To clarify the goal of this CG: it should not be a place to do unconstrained philosophical research but rather a forum to examine issues arising from the W3C technical community. Open discussion and precise descriptions of the minutiae of the Web will help guide the work in the CG, which should output short guides on precise topics to help case progress and discussions in other groups. The PhiloWeb Community group aims to undertake such discussions by bringing together experts from the web and the philosophical community to help the task of "philosophical engineering", a term coined by Tim Berners-Lee.

  • Portable Personal Data Preferences

    A problem with terms of service agreements is that they often require an all-or-none acceptance or rejection. In addition, they may be in a form that is not accessible to persons with disabilities making it difficult to make an informed decision. The mission of this community group is to find ways that help users understand what they are being asked to commit to, and to provide a finer grain of control in terms of what they are willing to share. The overall goal is to put control of personal data into an individual’s hands. The group's primary activity is to discuss and report on how to make terms of service agreements comprehensible to users and to provide a means by which users can express their preferences regarding their personal data. The reports may include descriptions of use cases, user interface wire frames, plain language proposals, and supports that educate users about personal data and data sharing. The group will define a way for users to express preferences regarding the collection, use, and disclosure of their personal information. These preferences will be "portable" in the sense that they are encoded once and can be used on a variety of platforms including websites, desktops, and mobile devices, among others. People interested in educating users regarding personal data and data sharing, inclusive user interface design, and the use of plain language in policies and service agreements are welcome. This group may publish specifications. Charter (WIP): https://inclusive-design.github.io/cg-portable-personal-data-preferences/CGCharter.html

  • Product Tracing & Blockchain

    WEB OF PRODUCT TRACEABILITY This is the landing page for Web of Product Traceability Community Group. In the modern commercial society, product traceability is an important technical system to support the business credit of enterprises.Product traceability is also widely used in product quality supervision, modern logistics, financing Mortgage, commercial consumption and other fields. Therefore, many countries and organizations attach great importance to the development of Traceability Technology. Many independent traceability systems have been built by different countries and organizations. Uniform standards will help to improve the interconnection between them. With the development of technology, two-dimensional code has gradually replaced the commodity bar code, and the data contained in the RFID tag can reach 64K bytes, or even more.The article code based on URL is compatible with traditional GS. 1 commodity code and other coding systems.Therefore, an open product traceability network can be established from bottom to top based on WWW technology. Master data, transaction data and event data can be described by XML / JSON technology. Technologies such as Internet of things and blockchain will also play an important role in the network.The web of product traceability community is aims to build an open traceability network that can run on the public Internet.The original closed traceback network will not disappear, they can access to the open network as an autonomous domain.In the field of product traceability, there are also problems of data mining and information security. The community is aims to build various application models and interfaces to mine the value of traceability data.In order to ensure that the traceability data is not leaked, the community also needs to formulate corresponding information security standards to strictly control the access rights of traceability data. This will be a very promising and exciting work. We expect more enterprises and experts to join in and build an open traceability network.

  • Property Graphs Model and API

    This group will explore the Property Graph data model and API and decide whether this area is ripe for standardization. Property Graphs are used to analyze social networks and in other Big Data applications using NoSQL databases. The group may want to investigate several extensions to the data model. For example, should nodes be typed; what datatypes are allowed for property values; can properties have multiple values and should we add collection types such as sets and maps to the data model? At the same time, we need to bear in mind that there are several Property Graph vendors and implementations and we may not want to deviate significantly from current practice. Existing Property Graph APIs are either navigational e.g. Tinkerpop or declarative e.g. Neo4j. For a W3C standard we may want to design a more HTTP and REST-oriented interface in the style of OData Protocol and OData URL Conventions. In this style, you construct URls for collections of nodes and edges. For example, a GET on http://server/nodes would return the collection of nodes on the server. A GET on http://server/nodes/in(type = ‘knows’ ) would return the collection of incoming arcs with type = ‘knows’ and a GET on http://server/nodes/out(type = ‘created’ ) would return the collection of outgoing arcs with type = ‘created’. Once a collection of nodes or arcs is selected with the URI, query operators can be used to add functions to select properties to be returned. Functions can also be used to return aggregate properties such as count and average. The group will deliver a recommendation to the W3C regarding whether and how the Property Graph work should be taken forward towards standardization.

  • Quick-fix support for XML

    Sometimes an error reported against an XML document can be fixed automatically, for example if the error refers to an unexpected attribute then an automatic fix will be to delete that unexpected attribute. We want to explore the issues related to applying quick fixes (like preserving DOCTYPE declarations, entities, etc.) and determine what actions will be needed be able to apply quick fixes on a document as well as a representation language to describe these actions. Quick fixes are especially interesting when we use Schematron for XML validation, as in this case the quick-fix should be specified by the schema author, so we have user-defined quick fixes. Imagine for example a business rule implemented in Schematron that says that a list should contain between 4 and 8 items. If we determine that there are two items then a quick fix will propose to add automatically two more items to the list or if the list has 10 items then a quick fix may propose to delete two items or to split the list in two lists, etc.

  • RDF and XML Interoperability

    The goal of this group is to 1) identify application areas in which the combined processing of XML and RDF data and tooling is beneficial; 2) identify issues that hinder the joint usage of the two technology stacks 3) formulate best practices to resolve the issues or propose standardization topics. The goal does not only take into account the data representation formats XML and RDF, but all related technologies (e.g. for XML: XSLT, XQuery; for RDF: RDF Schema, SPARQL) and selected XML (e.g. OData) or RDF vocabularies. The group should be driven by needs of industries that already deploy one or both technology stacks. This will also cover adjacent technologies like JSON with respect to the topics covered in this group. The outcome should focus not on a big architecture of how to work with XML and RDF, but on small building blocks (as best practices or standardization topics) that can be re-used across industries and application scenarios.

  • Research Object for Scholarly Communication

    Research investigations are increasingly collaborative and require ‘‘borrowing strength’’ from the outputs of other research. Conventional digital publications are becoming less sufficient for the scientists to access, share, communicate, and enable the reuse of scientific outputs. The need to have a community-wide container data model to encapsulate the actual research data and methods with all the contextual information essential for interpreting and reusing them is becoming more and more imperative, for the science, publisher, as well as digital library communities. A number of different community groups and projects are now creating some form of container, bundling or aggregation mechanism (particularly using ORE OAI), partially driven by the above goal. There is a clear need and benefit to facilitate a consensus among these representations. In the ROSC community group we aim to provide an open platform for gathering and discussing current development of various container models and their implementations. These data models should be driven by the need of facilitating the reuse and exchange of the actual digital knowledge and the inspection of the reproducibility of scientific investigation results. They should consider not only the data used, methods employed to produce and analyse that data, but also the people involved in the investigation and annotations about these resources, which are essential to the understanding and interpretation of the scientific outcomes. As outcomes from the community group we aim to facilitate the establishment of a community data model and a set of community agreements that can effectively assist the establishment of a new form of scholarly communication, that is a prominent issue of today. This group will not publish specifications.

  • Resilient Web

    Situations of interrupted work caused by accidental loss of connectivity or by intentional offline work are very frequent. Concerned by the negative effects of interruptions in users’ activities, we are investigating a new approach for the design and development of Web applications resilient to interruptions. In order to help users to recover from interruptions whilst navigating Web sites we propose a model-based approach. With this model we are able to design web interaction and to make decisions about how web sites are going to behave when they are interrupted due to a lack of connectivity. The aim of this group is not to create a way to make offline applications over the web, but we use the features provided by the HTML standard to make user interaction with web sites "interruption resilient”. We’ll work in defining the elements for making users interaction with the web resilient to interruptions.

  • Semantic Web in Health Care and Life Sciences

    The mission of the Semantic Web Health Care and Life Sciences Community Group (HCLS CG) is to develop, advocate for, and support the use of Semantic Web technologies across health care, life sciences, clinical research and translational medicine. These domains stand to gain tremendous benefit from intra- and inter-domain application of Semantic Web technologies as they depend on the interoperability of information from many disciplines. The HCLS CG provides a forum for supporting, developing and applying Semantic Web technologies across healthcare, life sciences, clinical research and the continuum of translational medicine. Within these contexts, the HCLS CG focuses on the use of Semantic Web technologies to realize specific use cases which themselves have a specific clinical, research of business values. As use cases are developed, HCLS CG can solicit advice on technical matters from other Semantic Web related groups and give feedback on the use of technologies based on the work they do. The CG may also develop ongoing and mutually productive liaisons with relevant external organizations in healthcare, life sciences, and clinical research, including organizations that are actively working on relevant standards and/or implementations to which the HCLS’s work might contribute.

  • SPARQL Maintenance (EXISTS)

    The "SPARQL Maintenance (EXISTS)" Community Group is a forum to discuss and address problems with the "EXISTS" feature in SPARQL 1.1. The SPARQL 1.1 suite of specifications and the SPARQL 1.1 test suite are frozen. A process exists to record errata and that will be one input to any working group chartered to revise SPARQL. In the meantime, SPARQL is being used in real-work systems in industry and public-sector. The user community expects a high degree of conformance across implementations. The EXISTS feature has been found to be problematic. This feature is used by the RDF Data Shapes Working Group. This community group will create CG Notes and accompanying test suites to describe one or more improvements with an emphasis on maintaining compatibility. This group is not producing specifications. Any tests produced by the will submitted to the RDF Test Suite Curation CG for long-term stewardship.

  • SPARQL-ML

    The technological advancement in computational power and the significant increase in data generation allowed the successful implementation and application of many machine learning methods that were not possible before. On the one hand side, those methods need a lot of data to succeed. On the other hand side, the Semantic Web community has successfully published a large amount of machine-readable data on the Web. RDF data is often accessible over not machine-learning-ready protocols. The purpose of this community is to discuss how to leverage machine learning methods in RDF data through the SPARQL query language and protocol.

  • Spec Annotation

    The current W3C process for commenting on specifications is complicated and discouraging to users. Discovering previous comments is also challenging, and leads to lost time. It's also difficult for spec editors to matching out-of-band comments sent through email or issue-trackers to the spec itself. Having an annotation sidebar that lets users create, review, and resolve spec comments would make the workflow much easier. For the past several months, the WebPlatform.org team has been working to integrate the Annotator project to allow spec annotations, and it is ready for experimental use for W3C working groups. The Spec Annotation Community Group will collect use cases and requirements, feature requests, and bug reports, and will help coordinate feature implementation and bug fixes as well as integration with other open annotation systems. This group will not publish specifications.

  • Speech API

    The goal and scope of this Community Group is to produce a JavaScript Speech API that supports the majority of use-cases in the Speech Incubator Group's Final Report, but is a simplified subset API, such as this proposal. For this initial specification, we believe that a simplified subset API will accelerate implementation, interoperability testing, standardization and ultimately developer adoption. This JavaScript Speech API will enable web developers to incorporate scripts into their web pages that can generate text-to-speech output and can use speech recognition as an input for forms, continuous dictation and control. Specification of HTML markup and a network speech protocol are out-of-scope of this Community Group.

  • Stroke Fonts

    An attempt to find ways of using stroke fonts in design workflows

    A stroked font is based on the idea of describing a collection of glyphs by their center line or the movement of a pen rather than their outlines. The center line, or skeleton, would then be styled either from inside the font, either from any software that acts downstream on the text, according to parameters that are yet to be defined. But might be based on the concept of an object following a path. This could be a very different approach than those embedded in the font formats currently in wide use. There will be a lot of issues to address for this to move forward. Drawing letters from their skeleton allow users for other styling options, but also allows the computer for a larger understanding of a glyphs shape as a whole or it's important features, regions, parts. Based on this understanding it woud be easier to algorithmically alter these glyphs' shapes -- while composing texts for example. It would enlarge the scope of what this group aims to do. Going towards a parametric approach of designing fonts, and considering the resulting transformation of the composition process. From fonts to lettering, from typography to writing. We aim to discover, adapt or develop a way to make these fonts usable and stylable in a variety of scenarios, such as web pages, canvas based design tools, as well as pen plotters, CNC, PCP and cartography design environments.

  • SVG Mapping

    The mission of SVG Mapping Community Group (SVGMapCG) is to build requirements for SVG based Web Mapping through a discussion of use cases regarding map services. One of the key technologies for SVG Web Mapping is dynamic Tiling & Layering, which realizes zoom and pan display of maps in an efficient manner. The other technologies for the mapping (e.g. Shared Path, Vector Effects and etc.) are also necessary. Although these functionalities will be standardized as part of SVG 2 in SVG WG, the focus of discussion is for general use and the discussion may lack particular aspects for map services. Therefore, our main scope is to investigate whether these generic functions are enough or not to resolve challenges inherent in mapping, and to provide WGs (e.g. SVG and Geolocation) feedback from our observation. Envisioned issues for Web Mapping are a common coordinate system for map contents and a projection. Another issue is a relationship to other GIS communities (OpenLayers, Open Street Map, WMS, and etc.) outside W3C. They have developed map-related standards and frameworks, and we need to clarify our interrelationship and consider collaboration if necessary. This group will not create specifications.

  • The Hardware Pixel

    A group for people who love pixels! This group is in support of exposing device pixel densities to web developers and letting web developers have the ability to use 'hardware pixels' instead of 'CSS pixels' on demand. Native developers have this affordance, why can't we? Hardware pixels! We want hardware pixels! ## What we want ## We want metrics! The hardware pixel density of a screen can live in the window.screen object as window.screen.pixelDensity, for example. The value would be the average of the vertical pixel density and the horizontal pixel density of the screen (in hardware pixels per unit). Vertical and horizontal pixel densities of the screen can be exposed in window.screen.verticalPixelDensity and window.screen.horizontalPixelDensity. Yes, the vertical and horizontal values don't always have a ratio of 1 across devices. Pixel Aspect Ratios are important for developers and designers that truly care about device-independence. ## How can it be done? ## Easy. The EDID data in modern screens tells us the width and height of a display in millimeters, the native resolution of the screen, and other interesting information. This info allows us to calculate a screen's hardware pixel density in pixels per millimeter with floating point precision. Exposing these values in window.screen is even more trivial. ## Why do we want these values? ## In this modern day, developers are moving towards device-independent development more than ever before. By exposing physical characteristics of a screen (when supported by the screen (just like how OpenGL is exposed through WebGL when supported by a device)) web developers will be able to make device-independent decisions on their development process. Currently, the lack of these metrics means that a web app can only look *almost* the same across devices, but not necessarily *exactly* as intended. We're engineers; *almost* is not enough. For example, suppose I want to make a push menu that is *always* 1 physical inch wide. This is currently not possible because inches in the web are "CSS inches", not physical inches. CSS units like centimeters, millimeters, and inches are currently unreliable across devices. You might think "why not just create a div element that is 1 cm wide, then get it's width in pixels and that's how many pixels per cm you have". Sure, that works, but those are *CSS* pixels per *CSS* centimeter. On top of that, not all operating systems operate at the same dpi, and to make matters worse not all devices have a devicePixelRatio of 1 (mines 2 by default in Mac OS X Yosemite). So the value that you'll get from this technique, if you adopt it right now, vary a *whole lot* across devices. We can't say with any confidence that something being displayed on various screens on multiple devices is 1 physical inch wide. Giving us these screen metrics will not only help us, it will help the future generation of developers because not only will exposing these screen metrics based on EDID info (when supported by the screen) get us closer to device-independent development more often, it will also promote the use of the EDID standard by screen manufacturers so that the next generation can benefit even more from the exposed screen metrics. ## Pixel Freedom for All! May the pixel be with you! ##

  • Trust & Permissions

    As the Open Web Platform expands, and apps are developed that access various sensitive resources, new ways of managing permissions to access these resources are likely to arise. This Community Group will explore and evaluate such ways based upon experience with native and hybrid platforms, and drawing upon research studies. This follows on from the Paris meeting on trust and permissions held on 3-4 September 2014, see [1]. Resources vary in sensitivity and timeliness, e.g. when and to whom a password should be disclosed is quite different from when access to the user’s webcam should be granted. Similarly, modes of obtaining user permission vary, including asking users upfront for permission when an app is installed or first run (exemplified in Android and Windows) or asking users for permission when the application is attempting to use a given capability (exemplified in iOS) and permission can even be obtained after the fact by inviting the user to continue or to cancel an action after it has occurred, i.e. asking for forgiveness rather than permission. In some cases, the user's actions can be taken as implicitly granting permission, such as the Windows file chooser dialog. A further approach is for users to delegate decisions on permissions to a trusted 3rd party. The goal of this CG is to develop and articulate best practices for which modes of obtaining permission best match which resource types, and make these best practices available to both platform developers (browser and operating system vendors) and app developers. Ideally the APIs offered to apps to obtain permission to access resources should be consistent across platforms, while allowing platforms the flexibility to present a user experience that meets each platform’s needs. The scope of this Community Group is limited to discussion and guidance on best practices, to review draft APIs from individual WG's, and pre-standardization work on promising ideas for better user experience obtaining permission, including trusted UI and trust delegation per Roesner et al, see [2]. Work on best practices will focus on the kinds of resources that need protection, the enumeration of good ways to obtain user permission, to dis-recommend permission models that are known to be problematic, and to recommend the preferred user experience for a given kind of resource. The main focus is on the Open Web Platform, but packaged apps are not excluded. This group will not publish Specifications.

  • TV Control API

    The convergence of Internet-based IPTV, Video-on-Demand (VoD), Personal Video, IP multicasting video, cellular multicasting video etc. with traditional broadcasting video, satellite video and cable video is emerging on market. The technology gap between web apps and native apps is rapidly narrowing. Thus a web-based application controlling various TV channels with detailed information regarding TV programs is becoming a more and more main stream TV control application for the integrated video service. Furthermore, in many regions TV broadcasters are developing web applications that can overlay their channel in a hybrid broadcast/broadband environment. Scope of Work The W3C TV Control API Community Group is to define an API layer that is agnostic of any underlying video sourcing technologies to enable a web-based application to: - provide EPG information, including the list of TV programs and related information such as channel number, producers, directors, actors, synopsis, rating etc., - control and switch the TV sourcing based on channel identifier from EPG data - interact with TV platform for presenting the TV program appropriately - interact with TV platform for presenting other supplemental content appropriately The underlying video sourcing method and technologies, the presentation technology and/or presentation application of TV program and supplemental content are all out of scope. Operating Guidelines This group operates under the rules of the Community and Business Group Process. All matters relating to intellectual property are governed by the Community Contributor License Agreement (CLA). All participants within this group agree that their discussions will follow the General Communications Policies.

  • URI Specification

    The URI Specification Community Group endeavors to produce a set of coherent, maintainable artifacts for use by implementors, developers, authors, and everyday users. We will achieve this by creating a formal specification of the ad hoc URI/URL standard described by RFC 3986/3987 and the WHATWG URL Living Standard. The deliverable is a single formal specification source document in Lem (http://www.cl.cam.ac.uk/~pes20/lem/) from which a typical standards document can be generated as well as a set of theorems over the concepts described and an executable test oracle for each specified function. Depending on community support and development of test generation tools, a test suite with proven specification coverage may also be delivered. If you think URI should work predictably and correctly and be able to be understood clearly, please join this group and give us your perspective!

  • User Identity on the Web

    Currently, more and more services are created on the web and require information about you, me, all of us. Therefore, users have to give away a lot of information about themselves to many different services. The point is that the users lose control of their identity on the web, by filling a lot of forms (e.g., through subscriptions). Privacy on the Internet is extremely important and must remain. Personal information is used by services we, sometimes, don't even know about, and it is a real problem. The aim of this group would be to think about new ways to identify individuals over the internet using trusted web based identities embedded directly into the core protocols of the web. At the same time it is important to maintain equilibrium between total privacy and providing information when needed, which means, when the user wants to.

  • Voting system

    There has been lengthy and recurrent discussions about reforming the voting system for AB/TAG elections. The current system is allegedly broken as it is stated by various members, but the AC is not willing to work on this unless someone comes up with a comprehensive explanation and proposal. There are many alternatives: * pick up one alternative voting system * work on a tool to create simulation * use this tool for **non official** ballot at the same time as an official ballot (which would be used with the current systen) All of these items have been proposed in various email threads in w3c-ac-forum and public-w3process list, not repeating the links here for the sake of conciseness. This group will not publish specifications.

  • W3C Developer Relations

    Developers and designers form an important audience for W3C standards, but the standards process itself is not an ideal way to engage with them. W3C has made strides in terms of developer relations in recent years, through W3Conf, Web Education XG and CG, easy access to W3C through community groups, more documentation, and online training. More can be done to reach more people and better reflect their interests in W3C. Initial ideas: * Create a developer relations activity or domain, to coordinate and explore different ways to directly engage with developers and designers, to gain early feedback on our specifications. * Make W3C a home for more useful documentation, demos, etc. * Support developer advocacy, in which ideas, use cases, and requirements for features or specification fixes are collected in detail from developers and designers, and presented to the appropriate W3C Groups. * Liaise with Members' developer relations departments on projects of mutual benefit. This group will not publish Specifications.

  • Web App Source Code Protection

    The goal of this community group is to explore solutions for protecting web app source codes. It is well-known that web page source codes are visible to the public due to the openness of the Internet and the W3C standards. With the advent of HTML5, the web apps become popular, especially the mobile web apps. Web apps can be classified as either Hosted App or Packaged App. The source code of Packaged Apps (such as the apps in Firefox OS or Tizen OS) are installed and running locally. Users can easily view the source code. Similarly front end source code of Hosted App can also be easily seen by anyone. In this case, the publicity of source codes becomes a problem. Because web developers never hope their web apps are easily copied by others. Therefore, this group intends to find mechanisms of code protection for web apps, especially for packaged apps, making the source codes (e.g. HTML, CSS, JavaScript), as well as relevant resource files (image, audio and video, etc.) cannot be seen easily. Thus, the interests of web developers will be protected.

  • Web Application Store

    Since the launch of Apple's App Store in 2008, developers found a market delivery channel that greatly reduced time-to-market and time-to-payment and provided a direct channel to consumers. The result: users started buying more and more smartphones, accessing app stores and downloading billions upon billions of apps. At same reason, web developers are also expressing interest in an app store model for the Web that would enable them to get paid for their efforts without having to abandon Web development in exchange for proprietary silos. The purpose for this Web Application Store community group is to discuss about the web application store, related technologies, and various issues for Open Web Application Store. This Web Application Store CG's activities include: * Tracking specifications and implementations related to Web Application Store. * Refining use cases to communicate specific needs of Web Application Store. * Discussing technological issues related to Web Apps & Web Application Store * Suggesting refinements or fixes to existing specifications to better meet the needs of the Web Application Development community * Evangelizing specifications to browser vendors. * Documenting how to best use open web standards for Web Application Store * Evangelizing open web standards and best practices for Web Application Store Anyone can join the Web Application Store Community Group.

  • Web Copyright

    Irrespective of whether we like it or not, of whether W3C or other SDOs eventually accept it or not, DRM seems slated to come to the Web platform. We are looking at video today, but books, apps, and therefore relatively arbitrary Web documents could easily be next. The business pressure to do so is such that there is little in the way that technology can do to stop this process. Our communities may produce everything from learned recantations to bitter rants, words will not suffice to address the problem. The only way in which we can decisively put a stop to DRM is by changing the legal system which can make it seem desirable to some. The goal of this group is to produce a set of realistic proposals for Web-compatible copyright legislation. Its focus is very much pragmatic, the idea being not to produce an idealistic laundry list for some free content utopia, but rather actionable proposals that stand a chance of passing into law. This group will not produce specifications.

  • Web fights covid19

    There is no doubt that the Web is demonstrating its potential in these hard times of the covid19 pandemic. The Web is allowing us to share information quickly and globally. Also, It is enabling the quick deployment of remote-working solutions as a response to the lockdown measures imposed by a majority of Governments. But the Web goes far beyond. Lots of Web ressources have been launched in the last weeks from different parts of the World supporting tools to fight the covid19: websites implementing AI screening and detection solutions; with data visualization tools; accessing bots and humans for telemedicine services; sharing information about medical resources... all these are some of the examples, and the list grows every day. This Community Group is proposed for achieving the following objectives: (1) to create a repository of already existing Web resources related to covid19 (2) to identify other Web-based initiatives which are on-going (3) to share Web-based initiatives of CG Members in order to get on-board other Members and achieve the maximum impact

  • Web Observatory

    The sister organisation of W3C, the Web Science Trust (www.webscience.org) proposes to create a global "Web Observatory". The Open Data movement and the Transparency Agenda are successfully advocating the release of very large institutional and commercial data sets describing social phenomena, economic indicators and geographic trends. This proliferation of data represents great opportunity for researchers and industry but this data abundance also threatens to make it ever more difficult to locate, analyse, compare and interpret useful information in a consistent and reliable way; a situation which can only get worse unless we can help stakeholders perform useful analysis rather than drowning in a sea of data. The Web Observatory will offer an institutional framework to promote the use of W3C and other standards in the development of; Semantic Catalogues to globally locate existing data sets, Collection Systems to gather new global data sets, and Analytics Tools and methodologies to analyse these data sets. This community group seeks to articulate the business and technical requirements for the Web Observatory.

    See the Web Payments Interest Group http://www.w3.org/Payments/IG/ This group was set up as a follow-up on the W3C Web Payments Workshop that took place 23-24 March 2014. The workshop participants advocated W3C to launch a dedicated steering group (W3C Interest Group) to engage further in the development of core standard technologies to better support payments on the Web. This community group is a first step in that direction, and will host the discussions around the future charter of the interest group. The objective is to ensure that all stakeholders are able to provide inputs on the role and actions of the future group, and to ensure that a critical mass of representatives from the different stakeholder groups are ready to engage in this work.

  • Web We Can Afford

    Most scientists now seem to agree that we've entered a new epoch dubbed the "Anthropocene", where the environmental consequences of human development have a tremendous impact on Earth's equilibrium. Those effects are already set in motion and will have far-reaching consequences in the coming years despite all the measures we could take to mitigate them (considering we simply do not fail to take action). While trying to avoid some of the consequences of the Anthropocene is an issue that is well-worth striving for, another task would be to reconsider the design of things at the time of the Anthropocene and that includes the Web. For instance, a 2008 study by the University of Dresden stated that if no measure was taken, the energy needed to power the infrastructure of the Web in 2030 would be tantamount to the energy consumed by humanity in 2008. The agendas of the stakeholders who are trying to set the Web forward in motion are mainly focused on adding new technological layers to the existing ones. Yet, the logic behind these developments remains that of tapping into unlimited resources, not limited ones. Lots of endeavors are currently focused on reshaping the Web into a "Web we want", a redecentralized open Web fit for an enlightened digital age. Those who advocate such an agenda and those who oppose it generally both share a common assumption: that enlightened or not, the future will be even more digital than the present. Yet, life at the time of the Anthropocene, at least in the coming decades, might not remain as pervasively digital as it is today. Other efforts that see the ongoing battle for the decentralization of the Web as an opportunity to “downscale” it (in particular in Africa) seem to be aware of that. Maybe it's time to take into account other perspectives on the future and concretely act towards building a sustain-able (Tony Fry) Web. In other words, a Web We Can Afford. This group would like to reconcile the development of the Web and an awareness to the environmental issues by appealing to Web architects and designers, eco-designers, activists, philosophers, social scientists, etc., so as to make the issue a public one to begin with, before devising a set of guidelines as a first step towards concrete action.

  • Web-Native

    The Web-Native Community Group is a focused initiative to bring the current developer community overrun by frameworks back to native web technologies, so that everyone can bank more on the platform and less on abstractions. This is a targeted intervention to the now sweeping "framework-first" thinking for a new "native-first" thinking among developers. Whatever were the reasons for the former at the time, it no longer aligns with the current state of the platform and its fast-evolving future. It is now, more so than ever, a compelling problem to fix, and this community group will do just that! We hope to build on the work of existing posts in the community, that are, at least, looking for a paradigm shift. More importantly, our key activity will be working with the developer community and other W3C community groups to: (1) implement strategies that engage the developer community to put native languages, APIs, and methodologies at the heart of their everyday work, and (2) facilitate proposals that can bring various common development paradigms to native implementation, or to say the least, provide low-level primitives to support higher-level implementations of these paradigms that represents the modern web.

  • WebAPI Discovery

    A group to develop a mechanism for the automatic discovery of WebAPIs, by extending the schema.org vocabulary. Increasingly, large online platforms and services provide one or more Web APIs for third-party developers. Moreover, many companies build WebAPIs as their primary product (Email API, SMS API, etc.). This has resulted in an explosion of the number of WebAPIs in recent years. Developers spend a significant amount of time searching for suitable WebAPIs to meet their needs. Our intention is to work closely with Schema.org to define a WebAPI-specific extension and promote usage of this extension among API owners. In the long run, our aim is to contribute this extension into the core Schema.org vocabulary. To achieve these goals we are seeking feedback and collaboration from API owners, DX specialists, API description language experts and maintainers of various API catalogs.

Webizing is really important, not only as a way of bootstrapping the web using large amount of legacy information, but because the existing systems have been researched and designed over the years and it is really important we do not lose the knowledge accrued during that process." --Tim Berners-Lee http://www.w3.org/DesignIssues/Webize.html This Group aims to webize as many existing systems and applications as possible, and is committed to producing 5 star linked data, in line with the original vision of the web.

  • World Archives of Sciences

    The internet has been considerable development in the world has led to an exponential growth in the number of online documents by scientists. In this sector, the current trend seems to be to digitize all funds scientific libraries and sample Museums and this internationally. Many of these documents: articles, monographs, academic work, digitized specimens and videos are now available online, but remained scattered on the canvas. They do not allow quick consultations and consolidation of information. The new generation of scientists studying species biodiversity, taxonomy, protection, conservation and many other natural sciences, wants more access and use these documents remotely and for free. They suffer, however, that some problem: too wide dissemination of data and information. To meet this expectation, we collect (for 10 years) and archive it all these documents in a single point: WAS World Archives of Sciences: WAS-Archives.org : Biodiversity, Zoology, Botany, Taxonomy, Entomology, Paleontology, Geology, Natural History WAS contributes to the development of Knowledge and World Heritage. It allows the recognition of scientific organizations (Museums, Universities...). He participated in an ambitious scientific archiving, Museums becoming true mine of information as well as the Libraries or Documentation Centers. In addition to the departments of Natural History: Zoology, Botany, Taxonomy, Entomology, Paleontology, Geology and Natural History, WAS also archive the academic work of Administrations, Professional Associations, Commercial Societies, Non-Profit Foundations and Universities that become our natural partners and complete the panorama of available public sources of sciences.
