For Wide Review: WCAG 2.2

The Accessibility Guidelines Working Group (AG WG) has published a Working Draft of Web Content Accessibility Guidelines (WCAG) 2.2 for wide review. This version has 9 new accessibility requirements (“success criteria”) since WCAG 2.1. The new success criteria address user needs of people with cognitive or learning disabilities, users of mobile devices, and users of ebooks. We want to hear from users, authors, tool developers, policy makers, and others about benefits from the new proposed success criteria, as well as how achievable you feel it is to conform to the new success criteria. Additional information is in the blog post Web Content Accessibility Guidelines (WCAG) 2.2 Draft for Review. Please submit comments by 18 September 2020.

TTML Profiles for Internet Media Subtitles and Captions 1.2 is a W3C Recommendation

The Timed Text Working Group has published TTML Profiles for Internet Media Subtitles and Captions 1.2 as a W3C Recommendation. IMSC 1.2 is the latest version of the IMSC standard, which defines profiles of the Timed Text Markup Language for worldwide subtitling and captioning interchange. IMSC is used in applications such as CMAF, DASH, IMF, ATSC, DVB, etc. and is designed to work with SMPTE-TT, EBU-TT-D and other regional practices. IMSC 1.2 adds support for downloadable font resources. This feature is intended to improve fidelity by providing clients the exact font used during authoring and allow images to be added to inline text content – while providing graceful fallback. IMSC 1.2 is otherwise primarily a maintenance release that fixes outstanding bugs and generally improves specification text.

Working Group Note: Web App Manifest — Application Information

The Web Applications Working Group has published a First Public Working Group Note of Web App Manifest – Application Information. This document is a registry of supplementary members for the Web App Manifest specification that provide additional metadata to an application manifest. This metadata can be used in a digital storefront or other surfaces where this web application may be marketed or distributed, or to enhance an installation dialog when installing a web application.

Updated Candidate Recommendation: Media Queries Level 4

The CSS Working Group invites implementation of an updated Candidate Recommendation of Media Queries Level 4. Media Queries allow authors to test and query values or features of the user agent or display device, independent of the document being rendered. They are used in the CSS @media rule to conditionally apply styles to a document, and in various other contexts and languages, such as HTML and JavaScript. Media Queries Level 4 describes the mechanism and syntax of media queries, media types, and media features. It extends and supersedes the features defined in Media Queries Level 3.

For Wide Review: Making Content Usable for People with Cognitive and Learning Disabilities

The Accessibility Guidelines Working Group (AG WG) and the Accessible Platform Architectures (APA) Working Group request wide review of the Working Draft “Making Content Usable for People with Cognitive and Learning Disabilities” from the Cognitive and Learning Disabilities Accessibility Task Force. We particularly request feedback on: Are any user needs or patterns missing or incorrect? and: Can any information be made easier to understand and implement? Comments are welcome through 4 September 2020.

Updated W3C Code of Ethics and Professional Conduct (CEPC)

W3C today adopted a new Code of Ethics and Professional Conduct (CEPC), developed by the Positive Work Environment Community Group. W3C’s Code of Ethics and Professional Conduct defines accepted and acceptable behaviors and promotes high standards of professional practice. The goals of this code are to:

  • Define acceptable and expected standards of behavior.
  • Provide a benchmark.
  • Ensure transparency in community and group management.
  • Ensure an environment where people can participate without fear of harassment.
  • Contribute to the identity of the organization.

This document supersedes the 2015 CEPC. Education and training materials are available from the Positive Work Environment public homepage.

JSON-LD 1.1 Specifications are W3C Recommendations

The JSON-LD Working Group has published the following specifications as W3C Recommendations:

  • JSON-LD 1.1—This specification defines JSON-LD 1.1, a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines.
  • JSON-LD 1.1 Processing Algorithms and API—This specification defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms.
  • JSON-LD 1.1 Framing—This specification allows developers to query by example and force a specific tree layout to a JSON-LD document.

Group Notes: Extensions to the OWL-Time Ontology — entity relations & temporal aggregates

The Spatial Data on the Web Interest Group has published two First Public Interest Group Notes:

OWL-Time [owl-time] is an ontology for temporal entities and relations between them. OWL-Time defines simple temporal entities (intervals and instants). The entity relations note adds four new relations: time:equals, time:hasInside, time:disjoint and time:notDisjoint which complement the original relations and allow for description of more relationships between temporal entities. The temporal aggregates note adds one new class time:TemporalAggregate and two properties time:hasPart and its inverse time:isPartof to allow for the description of arbitrary aggregates of temporal entities.

New Resource: Authoring Tool Accessibility Report Generator

The Accessibility Education and Outreach Working Group (EOWG) has published the ATAG Report Tool. Authoring tools are software and services used to create web content – such as content management systems (CMS) and what-you-see-is-what-you-get (WYSIWYG) HTML editors. W3C’s Authoring Tool Accessibility Guidelines (ATAG) addresses making the authoring tools themselves accessible and helping authors create more accessible web content. Learn more from the ATAG Overview. The new ATAG Report Tool helps authoring tool vendors and evaluators provide information to project managers, procurers, and others who need to know how well potential authoring tools support accessibility.

Updated Working Draft: Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them

The Accessibility Guidelines Working Group (AG WG) has published an updated Working Draft of Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them. This document is part of work on future accessibility guidelines, including WCAG 3.0. It explores the challenges of evaluating a broad range of websites and applications for conformance to Web Content Accessibility Guidelines (WCAG), and explores approaches for mitigating these challenges. Please see the blog post for information on this document and questions for review: Challenges with Accessibility Guidelines Conformance and Testing, and Approaches for Mitigating Them – blog.
