<trackbot> http://www.w3.org/WAI/APA/track/actions/2014

fe: Needs an accessiblity section

images and media should be able to be uploaded and downloaded with accessibility information

For example and image should be uploaded with the string for an img alt attribute or description.

Media should be associated with closed caption tracks.

You can probably do these things with the Micorpub API, however there are no instructions or examples how to do it. There are references to microformats 2, however accessibility isn't covered except in an ad hoc way.

js: if you can write up, we can give them forward
... we don' want them moving this forward without this being addressed

jf: Leone isn't available to be on the call, kicked off a thread in APA

s /APA/ARIA/

<JF> Leonie ie asked me to convey the following: The upshot is that the PL spec now includes a note to implementors, and I've kicked off a thread about API mappings in the ARIA WG - so there isn't anything else we can do within PL itself to address this AFAIK.

js: does that satisfy our concerns?

jf: we can't do much more

<JF> scribe: JF

FE: allows properties to be defined, but noyt really maps back to rendiering

... thee may be some real a11y benefits here

2 examples: COGA personalization, and for graphics (color blind, large charts, etc.)

FE: also instructional images, shift colors, widen line widths, etc.

May be able to reference alternative imagery (icons) etc.
