  • Colloquial Web

    Status: The group closed on 12 December 2011 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.

  • Core Mobile Web Platform

    This group closed in September 2013. Work has moved to the Web and Mobile Interest Group ( The goal of the Core Mobile Web Platform Community Group (CG) is to accelerate the adoption of the Mobile Web as a compelling platform for the development of modern mobile web applications. In order to achieve this mission, the CG will bring developers, equipment manufacturers, browser vendors, operators and other relevant members of the industry together to agree on core features developers can depend on, create related conformance test suites and provide to W3C (and non-W3C) groups use cases, scenarios, and other input related to successful mobile development. Read the full charter:

  • Digital Publication

    This Community Group closed on 5 December 2013. For discussion on this topic, please refer to the Digital Publishing Interest Group: 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.

  • 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).

  • 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,,,,, 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.

  • Future of e-payments

    This group was created to invent and support new and more secure methods for payments over the internet. Using one's credit card is insecure while using online pay through a third party is tedious, costly and not without legal issues. There is a huge demand for secure online paying. It is time to give the people what they want. It is time to turn the browser into a e-wallet.

  • Hyper Application Markup Language

    Hyper Application Markup Language (HAML) will describe a structure of a web application in a similar way like HTML describe a structure of a single page. If HTML standard allows to create World Wide Web of hyperlinked documents, HAML will allow to create a World Wide Application a Web of hyperlinked reusable micro applications.

  • 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.

  • Livestock Data Interchange Standards

    A group of dairy and sheep/beef organisations in New Zealand have agreed to collaborate on standardising the interchange of data about farm animals (livestock) and the management, health, and production information that is recorded for these animals. There are reasons why it is timely for the New Zealand dairy industry in particular to work on these problems, but we intend the work to support multiple species and to draw on previous international work and be relevant for use internationally.

  • Oil, Gas and Chemicals

    The Oil, Gas and Chemicals Community Group is intended to study and possibly demonstrate applications of Semantic Web technology to business issues in those industries. An example of the topics the Group could focus on is information describing the equipment used in major capital projects, with an eye to integration of that information with other major parts of the value chain such as production, maintenance and facilities engineering information systems. Another possibility is open publishing of catalog or metadata records according to published ontologies so that the published records can be queried, aggregated and analyzed in order to improve the efficiency and intelligence of searching for relevant resources.

  • Web Payments Charter Development

    This group is now closed; see the Web Payments Interest Group 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. This group will not publish specifications.
