W3C Security Disclosures Best Practices is a W3C Team Submission

screenshot of title and logos for sdbpW3C published a Team Submission of W3C Security Disclosures Best Practices, a proposal for security and privacy disclosure programs, which will serve as a basis for further work in the space of security and privacy researchers protection, further to our announcement late January. This document contains a template intended for organizations interested in protecting their users and applications from fraud, malware, and computer viruses, as well as interested in ensuring proper adherence to security and privacy considerations included in W3C Recommendations. It also helps to support broad participation, testing, and audit from the security community to keep users safe and the web’s security model intact.

In the coming days, the W3C Director will send the W3C Membership a Call for Review for the Encrypted Media Extensions Proposed Recommendation; and solicit feedback and expression of interest for the specification and the W3C Security Disclosures Best Practices Team Submission.

W3C updates its Process Document

W3C Membership approved the 1 March 2017 W3C Process Document, which becomes in effect today. Notable major changes of the 2017 update include:

  • A process for marking a Recommendation as Obsolete (distinct from Rescinding a Recommendation);
  • Voting mechanism used for AB and TAG elections is Single Transferable Vote;
  • Clarified the process for continuing work on a specification initially developed under another charter (aka Supergroups).

You may read more in the W3C Blog post “What’s new in the W3C Process 2017?“. This document was developed between the W3C Advisory Board and the public Revising W3C Process Community Group.

First Public Working Draft: Web Content Accessibility Guidelines 2.1

Web Content Accessibility Guidelines (WCAG) 2.1 has been published as a First Public Working Draft. This will be the first update to Web Content Accessibility Guidelines since WCAG 2.0. Sites that conform to WCAG 2.1 will also conform to WCAG 2.0, which means they meet the requirements of any policies that reference WCAG 2.0, while also better meeting the needs of users on the current Web. This first draft includes 28 new Success Criteria, three of which have been formally accepted by the Working Group and the remainder included as proposals to provide an opportunity for early feedback. Public feedback will be important to next steps on these proposals.

Further information is available in the blog post: Web Content Accessibility Guidelines 2.1 First Public Working Draft.

Please comment by filing GitHub issues in the WCAG 2.1 repository or, if this is not feasible, by email to public-agwg-comments@w3.org, by 31 March 2017. Read about the Accessibility Guidelines Working Group and the Web Accessibility Initiative (WAI).

W3C Begins Standards Work on Web of Things to Reduce IoT Fragmentation

W3C at MWC 2017 illustrationTo further the growth of market for IoT devices and services, W3C has launched the Web of Things Working Group to develop initial standards for the Web of Things, tasked with the goal to counter the fragmentation of the IoT; reduce the costs of development; lessen the risks to both investors and customers; and encourage exponential growth in the market for IoT devices and services.

In advance of W3C’s presence at Mobile World Congress 2017 next week, where W3C executives will be available on 27-29 February, W3C CEO Dr. Jeff Jaffe commented, “There are huge, transformative opportunities not only for mobile operators but for all businesses if we can overcome the fragmentation of the IoT. As stewards of the Open Web Platform, W3C is in a unique position to create the royalty-free and platform-independent standards needed to achieve this goal.

Read the Media Advisory to learn about the technical approach the Working Group will take and the broad range of collaboration.

Three recommendations to enable Annotations on the Web

The Web Annotation Working Group has just published a Recommendation for Web Annotation in the form of three documents:

  • Web Annotation Data Model—specification describes a structured model and format, in JSON, to enable annotations to be shared and reused across different hardware and software platforms. Common use cases can be modeled in a manner that is simple and convenient, while at the same time enabling more complex requirements, including linking arbitrary content to a particular data point or to segments of timed multimedia resources.
  • Web Annotation Vocabulary—specifies the set of RDF classes, predicates and named entities that are used by the Web Annotation Data Model. It also lists recommended terms from other ontologies that are used in the model, and provides the JSON-LD Context and profile definitions needed to use the Web Annotation JSON serialization in a Linked Data context.
  • Web Annotation Protocol—describes the transport mechanisms for creating and managing annotations in a method that is consistent with the Web Architecture and REST best practices.

The group has also produced two additional Working Group Notes:

  • Embedding Web Annotations in HTML—describes and illustrates potential approaches for including annotations within HTML documents. Examples also are included illustrating the use within an HTML document of annotation Selectors as fragment identifiers.
  • Selectors and States—selecting part of a resource on the Web is an ubiquitous action. This document does not define any new approach to selection; instead, it relies on the formal specification and the semantics in the Web Annotation Data Model. The current document only “extracts” Selectors and States from that data model; by doing so, it makes their usage easier for applications developers whose concerns are not related to annotations.

First Public Working Drafts: CSS Timing Functions Level 1; CSS Containment Module Level 1

The CSS Working Group has published two First Public Working Drafts today:

  • CSS Timing Functions Level 1, a module that describes a way for authors to define a transformation to be applied to the time of an animation. This can be used to produce animations that mimic physical phenomena such as momentum or to cause the animation to move in discrete steps producing robot-like movement.
  • CSS Containment Module Level 1, a module which describes the ‘contain’ property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.

W3C Workshop Report: Smart Descriptions and Smarter Vocabularies (SDSVoc)

workshop attendees group pictureW3C published today the report from the W3C “Smart Descriptions & Smarter Vocabularies (SDSVoc)” workshop, held on 30 November – 1 December 2016 in Amsterdam.

The report contains an executive summary and conclusions, as well as a brief summary and visual report of each session, with links to all presentation slides. The event’s agenda also links to the papers received and the rough notes taken throughout the event. The clear conclusion from the well attended workshop was that a new Working Group is needed to achieve two goals:

  1. Revise and expand the Data Catalog Vocabulary, DCAT to cover versioning, data series, APIs and more.
  2. Develop the concepts of data profiles (cardinality constraints and enumerated allowed values) and, from that, the mechanisms for content negotiation by those profiles. Following a careful analysis of the current state of the art, presented at the workshop, an Internet Draft is already in preparation on this topic. The WG’s role will be to put this in context and explain how fallback mechanisms can be used.

We’ve shared advance notice today that the W3C team is working on a draft charter for a new Data Exchange Working Group, and encourage public comments and suggestions on the draft charter in the dxwg GitHub issue repository.

We thank our Workshop sponsors: the EU-funded VRE4EIC project and Informatie Vlaanderen, the Flemish government’s digital agency, as well as our host, CWI, for making this event possible.

Spatial Data on the Web Best Practices Note Published

The Spatial Data on the Web Working Group has published a Group Note of Spatial Data on the Web Best Practices. This document advises on best practices related to the publication and usage of spatial data on the Web; the use of Web technologies as they may be applied to location. The best practices are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application. These best practices suggest a significant change of emphasis from traditional Spatial Data Infrastructures by adopting a Linked Data approach. As location is often the common factor across multiple datasets, spatial data is an especially useful addition to the Linked Data cloud; the 5 Stars of Linked Data paradigm is promoted where relevant.

Ready-made Counter Styles Note Published

The Internationalization Working Group has published a Working Group Note that contains templates for counter styles used by various cultures around the world. It can be used as a reference for those wishing to add user-defined counter styles in their CSS style sheets. The content of this document was originally part of the CSS Lists and Counters specification, but is now published as a standalone document. It is expected that the document will be updated from time to time to include new counter styles.

First Public Working Draft: International text layout and typography index

The Internationalization Working Group has published a First Public Working Draft of International text layout and typography index. This document points browser implementers and specification developers to information about how to support typographic features of scripts or writing systems from around the world, and also points to relevant information in specifications, to tests, and to useful articles and papers. It is not exhaustive, and will be added to from time to time.
