ARIA, Web 2.0 and Accessibility

Web 2.0 applications pose some new problems for assistive
technologies, which have mostly relied on the ability to gather &
process data from static web pages. Now we are looking for ways to
respond rapidly to flexible & changing content. One
emerging standard is ARIA

(ARIA = Accessible Rich Internet Applications)

The field was well covered in the Accessibility 2.0
panel discussion from May 16, 2007 (with archives & transcript, & a question from me).
