W3C Advisory Committee Elects Technical Architecture Group

8 January 2019 | Archive

W3C TAG logo  The W3C Advisory Committee has elected the following people to the W3C Technical Architecture Group (TAG): Alice Boxhall (Google), Sangwhan Moon (Odd Concepts) and Theresa O’Connor (Apple). They join co-Chair Tim Berners-Lee and continuing participants, Daniel Appelquist (Samsung Electronics; co-Chair), David Baron (Mozilla Foundation), Hadley Beeman (W3C Invited Expert), Kenneth Rohde Christiansen (Intel Corporation), Peter Linss (W3C Invited Expert; co-Chair), and Lukasz Olejnik (W3C Invited Expert). Yves Lafon continues as staff contact. Many thanks to Travis Leithead (Microsoft) and Alex Russell (Google), whose terms end at the end of this month.

The mission of the TAG is to build consensus around principles of Web architecture and to interpret and clarify these principles when necessary, to resolve issues involving general Web architecture brought to the TAG, and to help coordinate cross-technology architecture developments inside and outside W3C. The elected Members of the TAG participate as individual contributors and not representatives of their organizations. TAG participants use their best judgment to find the best solutions for the Web, not just for any particular network, technology, vendor, or user. Learn more about the TAG.

New version of the Roadmap of Web Applications on Mobile

7 January 2019 | Archive

icon representing mobile life-cycleW3C has published a new version of its Roadmap of Web Applications on Mobile, an overview of the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context.

The contents of the roadmap have been updated to follow the evolution of the Web platform since July 2018. See the Change history for details. This new version highlights exploratory work recently started in the Web Platform Incubator Community Group (WICG) to close the gap with native:

Browser support for some of the specifications mentioned in the roadmap has improved since publication of the latest version of the roadmap in July 2018. For instance, Media Queries Level 4, described in Device Adaptation is now supported by all main browsers. Picture-in-Picture is now also supported in Firefox mobile, and has experimental support in Safari (see Media).

Sponsored by Beihang University, this project is part of a set of roadmaps under development in a GitHub repository to document existing standards, highlight ongoing standardization efforts, point out topics under incubation, and discuss technical gaps that may need to be addressed in the future. New versions will be published on a quarterly basis, or as needed depending on progress of key technologies of the Web platform. We encourage the community to review them and raise comments, or suggest new ones, in the repository’s issue tracker.

First Public Working Drafts: The Profiles Ontology; Content Negotiation by Profile

18 December 2018 | Archive

The Dataset Exchange Working Group has published two First Public Working Drafts today:

  • The Profiles Ontology is an RDF vocabulary to describe profiles of (one or more) standards for information resources. It describes the general pattern of narrowing the scope of a specification with additional, but consistent, constraints, and is particularly relevant to data exchange situations where conformance to such profiles is expected and carries additional context. The Profiles Ontology enables profile descriptions to specify the role of resources related to data exchange such as schemas, ontologies, rules about use of controlled vocabularies, validation tools, and guidelines. The ontology may however be used to describe the role of artifacts in any situation where constraints are made on a the usage of more general specifications.
  • Content Negotiation by Profile describes how Internet clients may negotiate for content provided by servers according to profiles. This is distinct from negotiating by Media Type or Language: the profile is expected to specify the content of information returned, which may be a subset of the information the responding server has about the requested resource, and may be structured in a specific way to meet interoperability requirements of a community of practice.

First Public Working Draft: CSS Fragmentation Module Level 4

18 December 2018 | Archive

The CSS Working Group has published a First Public Working Draft of CSS Fragmentation Module Level 4. This module describes the fragmentation model that partitions a flow into pages, columns, or regions. It builds on the Page model module and introduces and defines the fragmentation model. It adds functionality for pagination, breaking variable fragment size and orientation, widows and orphans.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc.

Two Working Drafts Published by the Cognitive and Learning Disabilities Accessibility Task Force

11 December 2018 | Archive

The Accessible Platform Architectures Working Group and Accessibility Guidelines Working Group have published a First Public Working Draft of Making Content Usable for People with Cognitive and Learning Disabilities and an updated Working Draft of Cognitive Accessibility Roadmap and Gap Analysis, developed by the Cognitive and Learning Disabilities Accessibility (Coga) Task Force. The Making Content Usable for People with Cognitive and Learning Disabilities gives advice on how to make Web content and Web applications usable for people with learning and cognitive disabilities. It was previously an appendix to Cognitive Accessibility Roadmap and Gap Analysis. More information is available in the WAI announcement email. Read about the Web Accessibility Initiative (WAI).

Comments are welcome through 14 January 2019.
