For Wide Review: WCAG 2.2
11 August 2020 | Archive
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
4 August 2020 | Archive
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.
