Web Accessibility

Web content is growing ever richer through the use of javascript. Indeed,
today's web is becoming an application delivery mechanism rivaling the desktop
in functionality.

To engineer accessibility support for rich web content and for web delivered
applications, the World Wide Web Consortium's (W3C) Protocols and Formats
Working Group, part of the W3C's Web Accessibility Initiative (WAI), has
developed a suite of specifications called Accessible Rich Internet
Applications (ARIA). ARIA technology introduce metadata to web content, and
support mapping web delivered controls to operating system accessibility APIs
such as Open A11y's AT-SPI/ATK on Linux, Solaris, and Aix, and such as
Open A11y's IAccessible2 on Microsoft Windows. ARIA is supported today by Firefox3, and
will be supported by Internet Explorer 8.


Terms and Concepts

ARIA = Accessible Rich Internet Applications
mapping web to accessibility apis
by defined role
	state data
	applicable properties

Intended for interoperability across languages and operating systems

Depends on authoring support
Our expectation is that widget libraries will directly support ARIA
ARIA in javascript can be tested for accessibility using IBM's Eclipse based
tool called "raven."

Both at-spi/atk and aria support mainstream realtime testing
e.g. dogtail and ldtp on Linux
