Also ARIA became a bit of a buzz since only three days before Microsoft announced support for it in Internet Explorer 8. So there is partial support in Firefox 1.5, more in Firefox 2.0, and full support including liveregions for dynamically updated content in Firefox 3.0. Also Opera 9.5 has it. It can be used today as it doesn’t break old browsers, they will simply ignore the new attributes. Don’t hesitate, you can do good with it right now.

In the meantime Aaron Leventhal and his fellows were busy negotiating with members of the HTML5 working group to find a way of implementation without namespacing. So as of Firefox 3.0 it will be <img role="checkbox" aria-checked="false" /> instead of the previous namespaced notation aaa:checked="false".

Microsoft also thought about addressing the new attributes in the DOM, alas they did it the old proprietary way instead of sitting at a virtual or real table with the other browser vendors and thinking of a common way to do this. Opera’s Anne van Kesteren and the participants at the Browser Wars panel at SXSW were picking heavily on that subject. I believe the IE team got the message, but for the moment I would suggest to ignore the non-standard DOM attributes.

Thanks again to Gez, Becky, Lisa, and Shawn for their input and help. You made this a first-class experience!

South by Southwest (SXSW) is a huge conference for interactive media as well as a film and music festival in Austin, Texas, March 7-11, 2008. Every year it attracts the best designers and developers, and there is an immense number of panels to choose from. Exactly 128, out of which 80 are chosen from an open submission process.

Gez Lemon and I plan to run a panel called “Get Rich, Remain Accessible,” naturally about WAI ARIA (Accessible Rich Internet Applications). Gez wrote a great article about ARIA liveregions, and I wrote that article at A List Apart, so it’s the perfect team. Together we would like to present:

1. The accessibility problems introduced by the current trend of web applications,
2. new ways to add semantic meaning, communicate importance, define relationships, and give focus to elements using WAI-ARIA,
3. how to limit the impact of these problems whilst WAI-ARIA is gaining support by user-agents, and techniques that work right now.

It would be nice if you took the time to vote for us at the SXSW panel picker application. The voting process is open until 11:59 pm, September 21. If you push our presentation to the top 80 you will ensure Gez and I actually make every effort to attend the conference as we will get free tickets for ourselves. Spread the word …
