Subject: HTML5 Image Description Extension (longdesc) is a Proposed Recommendation

Dear WAI Interest Group Participants,

The HTML5 Image Description Extension (longdesc) has been published as a Proposed Recommendation at:

This specification ("HTML5-longdesc") enables web authors to provide longer textual descriptions for complex images. HTML5-longdesc is an extension specification that is part of the HTML5 family of specifications [1]. HTML5-longdesc is part of W3C's work to ensure that the Open Web Platform [2] is accessible to people with disabilities [3].

HTML5-longdesc has been developed in the HTML Accessibility Task Force [4], a joint task force of the HTML Working Group and the WAI Protocols and Formats Working Group (PFWG).

*Proposed Recommendation, Implementations, Comments*:

Proposed Recommendations are published when there are at least two confirmed implementations of each feature of the specification and it is ready for W3C Membership endorsement. Proposed Recommendation and other document stages are introduced in How WAI Develops Accessibility Guidelines through the W3C Process at <http://www.w3.org/WAI/intro/w3c-process>;.

The HTML Image Description Extension Implementation report is available at:

Comments are welcome by 16 January 2014. Information on how to comment is available in the status section of the document at:

Thank goodness the W3C is considering bringing back the longdesc attribute.

Often, the majority of graphics in STM-G materials (science, technical,
medical and government) can't be adequately described with Alt-text.

Is there any word on the street about something similar for PDFs?
