User Agent Accessibility Guidelines 2.0 and UAAG 2.0 Reference published as Working Group Notes

The User Agent Accessibility Guidelines Working Group (UAWG) has published User Agent Accessibility Guidelines (UAAG 2.0) and UAAG 2.0 Reference as W3C Working Group Notes. UAAG 2.0 defines how browsers, media players, and other “user agents” should support accessibility for people with disabilities and work with assistive technologies. Although W3C does not currently have plans to advance UAAG 2.0 to Recommendation, the need and opportunity to improve accessibility in user agents still exists. We hope that this work will be continued in future combined Guidelines group. UAAG 2.0 provides specific accessibility guidance for user agent developers who want to build a better user experience for all users. See the UAAG Published as Notes e-mail for additional info.

ATAG 2.0 is a W3C Recommendation

The Authoring Tool Accessibility Guidelines (ATAG) 2.0 was published today as a completed web standard. ATAG provides guidelines for designing web content authoring tools that are both more accessible to authors with disabilities (Part A) and designed to enable, support, and promote the production of more accessible web content by all authors (Part B). Selecting authoring tools that conform to ATAG 2.0 can facilitate the process of creating accessible Web content, and can also remove barriers to content creation by people with disabilities. Implementing ATAG 2.0 has been published as a Working Group Note to provide additional explanation, examples and resources for the ATAG 2.0 success criteria. (2015-Sept-24)
