Dear John, dear all,

first of all thank you for the job done. Great!

In the meanwhile, I have extended the table you have provided. You can file the updated version here [1].
@all: please, take a look at the terminology section, whether it makes sense for you or not. Your comments are very very welcome.

For better understanding, I have also provided small explanation pictures for the three different client concepts. You can find them in the table or separate for the fat client [2], thin client [3] and zero client [4] accordingly.

Subject: [Cloud Browser] My To-Do's

Hi all,

As discussed on today’s call, I’ve made some changes to the wiki:

Moved Terminology into a table to accommodate alternative names/terms for concepts being discussed: https://www.w3.org/2011/webtv/wiki/Main_Page/Cloud_Browser_TF/Architecture#Terminology

Added a new section to Use Cases for accessibility, and provided some backgrounder links there: https://www.w3.org/2011/webtv/wiki/Main_Page/Cloud_Browser_TF/UseCases#accessibility

Linked the Architecture page to the main Cloud Browser page (because it wasn’t there before):

I also mentioned Shadow DOM on the call today, and more details about that can be found at:

I’m not sure at this point whether this is relevant or not, but as explained, this concept was worked out to address accessibility requirements for the <canvas> element in HTML5, which essentially allowed the browser to ‘paint’ pixels to the screen (and animate them, both via JavaScript), but lacked any kind of scaffolding or framework that the Accessibility APIs could interact with. Shadow DOM addressed that problem, and is in production today. I’ve also added a link from Steve Faulkner that provides a primer on the accessibility tree requirements, as well as a link to the Core Accessibility API mappings – hope this helps.
