For Review: Updated Techniques for Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines Working Group (WCAG WG) requests review of draft updates to Notes that accompany WCAG 2.0: Techniques for WCAG 2.0 (Editors’ Draft) and Understanding WCAG 2.0 (Editors’ Draft). Comments are welcome through 12 August 2014. (This is not an update to WCAG 2.0, which is a stable document.) To learn more about the updates, see the Call for Review: WCAG 2.0 Techniques Draft Updates e-mail. Read about the Web Accessibility Initiative (WAI).

Developers Guide to Features of Web Accessibility Evaluation Tools Draft Published

The First Public Working Draft of Developers’ Guide to Features of Web Accessibility Evaluation Tools was published today by the Evaluation and Repair Tools Working Group (ERT WG). The document describes features that web authoring tools and quality assurance tools can incorporate to support web accessibility evaluation. It is useful for tool developers to get introductory guidance on these features, and is useful for people who want to compare tools, for example, during procurement. The document is intended to promote awareness of accessibility evaluation tool features and to encourage tool developers to include relevant features so that tools better support Web Content Accessibility Guidelines (WCAG) 2.0 conformance evaluation.

W3C Training: HTML5 and Responsive Web Design

W3DevCampus Registration is now open for two new online courses from W3C:

  • HTML5 [Register]. This course runs for 6 weeks, starting 22 September 2014. In addition to a JS crash course, numerous interactive examples and an “animated monster” contest, this new edition gives an introduction on Web components.
  • Responsive Web Design [Register]. This course runs for 4 weeks starting 3 October 2014. This course focuses on best practices, accessibility and optimization.

An early bird rate is available for both courses until 24 August. Learn more about W3DevCampus, the official W3C online training for Web developers and watch the intro video.

First Draft of Mixed Content Published

The Web Application Security Working Group has published a First Public Working Draft of Mixed Content. This specification details how user agents can mitigate risks to security and privacy by limiting a resource???s ability to inadvertently communicate in the clear, or to expose non-public resources to the web at large. This specification describes how and why user agents disallow rendering and execution of content loaded over unencrypted or unauthenticated connections in the context of an encrypted and authenticated document.

W3C Launches Push for Social Web Application Interoperability

W3C today launched a new Social Activity to develop standards to make it easier to build and integrate social applications with the Open Web Platform. Future standards —including vocabularies for social applications, activity streams, embedded experiences and in-context actions, and protocols to federate social information such as status updates— will address use cases that range from social business applications, to cross-organization federation, to greater user control over personal data. Read the complete joint press release with OpenSocial Foundation.

W3C chartered two groups today to carry out these activities:

  • The Social Web Working Group will define the technical standards and APIs to facilitate access to social functionality as part of the Open Web Platform. These include a common JSON-based syntax for social data, a client-side API, and a Web protocol for federating social information such as status updates.
  • The Social Interest Group will co-ordinate messaging around social at the W3C and formulate a broad strategy to enable social business and federation. It will harvest use-cases and review specifications produced by technical working groups in the light of those use-cases.

The Social Web Working Group’s first face-to-face meeting will take place the last week of October, as part of TPAC 2014, W3C’s annual gathering of Working Groups.

W3C Invites Implementations of Polyglot Markup: A robust profile of the HTML5 vocabulary

The HTML Working Group invites implementation of the Candidate Recommendation of Polyglot Markup: A robust profile of the HTML5 vocabulary. It is sometimes valuable to be able to serve HTML5 documents that are also well formed XML documents. An author may, for example, use XML tools to generate a document, and they and others may process the document using XML tools. The language used to create documents that can be parsed by both HTML and XML parsers is called polyglot markup. Polyglot markup is the overlap language of documents that are both HTML5 documents and XML documents.

The HTML Working Group also published today an updated Candidate Recommendation of Media Source Extensions. Learn more about the HTML Activity.

Web Annotations on the Horizon

Annotation, the act of creating associations between distinct pieces of information, is a widespread activity online in many guises but currently lacks a structured approach. People comment about online resources using tools built into the hosting web site, external web services, or the functionality of an annotation client. When reading eBooks, people make use the tools provided by reading systems to add and share their thoughts or highlight portions of texts. Comments about photos, videos, and audio tracks, questions or clarifications about data, maps, and social media posts or mentions are all forms of annotation.

However, annotation currently lacks a structured approach. Comments are siloed inside the blog or comment system hosted and controlled by the publisher of the original document, or inside an eBook reader. They aren’t readily available for syndication or aggregation, and it’s difficult to find more comments by an insightful author if they are scattered around different places on the web. Worthwhile commentary is obscured by trolling, spam, or trivial comments. These are challenges both social and technical.

In April, W3C convened a Workshop on Annotations to discuss these challenges. Today W3C published a Workshop summary with links to slides, videos, and position papers.

Today W3C also invites review of a draft charter for a new Web Annotation Working Group based on the Workshop discussion. The group will develop an open approach for annotation, making it possible for browsers, reading systems, JavaScript libraries, and other tools, to develop an annotation ecosystem where users have access to their annotations from various environments, can share those annotations, can archive them, and use them how they wish.

The public is invited to comment on the draft charter.

Character Model for the World Wide Web: String Matching and Searching Draft Published

The Internationalization Working Group has published a Working Draft of Character Model for the World Wide Web: String Matching and Searching. This document builds upon on Character Model for the World Wide Web 1.0: Fundamentals to provide authors of specifications, software developers, and content developers a common reference on string identity matching on the World Wide Web and thereby increase interoperability. Learn more about the Internationalization Activity.

Draft Model for Tabular Data and Metadata on the Web, and a Draft Metadata Vocabulary for Tabular Data Published

The CSV on the Web Working Group, part of the Data Activity, has published two Working Drafts today:

  • The Model for Tabular Data and Metadata on the Web outlines a basic data model, or infoset, for tabular data and metadata about that tabular data. The document also contains drafts for various methods of locating metadata; finally, it also contains some non-normative information about a best practice syntax for tabular data and for mapping into that data model. The work also contributes to the standardisation of CSV syntax by IETF (as a possible update of RFC4180).
  • The Metadata Vocabulary for Tabular Data defines a vocabulary for metadata that annotates tabular data. This can be used to provide metadata at various levels, from collections of data from CSV documents and how they relate to each other down to individual cells within a table. The vocabulary is defined using JSON, in a manner compatible with JSON-LD. This document is a First Public Working Draft.

If you wish to make comments regarding these documents, please send them to public-csv-wg@w3.org.
