Yesterday during the meeting we found two implementations for 1.8.10 IE and QQ. Both use the same rendering/UI engine...IE. Judy wondered if that was really 2 implementations. I queried several folks about this issue. Ultimately, it is the working group that defines the implementation rules, but we will have to defend them to the director. The consensus was that we ought to have implementations from at least 2 different rendering engines for each SC. Additionally, I checked around with people who know engines...and mobile engines are substantially the same as the desktop engines. I think we need to have a discussion about this topic, and determine our rules for determining valid implementations. I propose that for each SC we have implementations from 2 different rendering engines. If we find more (other engine or mobile version) so much the better. I think this would work for SCs pertaining to content. I am checking on the the User Interface of the browsers. Are the user interface of browsers with the same rendering engine different code bases or just skins? How do we find out? If the user interface code is unique to the browser then I think we could have 2 different implementations from different browser with the same rendering engine. But, only for SCs pertaining to UI components (e.g. preference settings). Rendering Engines Gecko IE - Trident Blink Webkit Presto (opera) - in maintenance mode but still out there. also, found UC Browser (400 million mobile users) java only mobile browser on all platforms (except Apple), based on webkit but call engine - U3. http://en.wikipedia.org/wiki/UC_Browser http://www.ucweb.com/English/UCMobileCompany/about.html http://technode.com/2011/06/13/chinese-browser-vendor-uc-released-new-engine-u3/ -- Jim Allan, Accessibility Coordinator & Webmaster Texas School for the Blind and Visually Impaired 1100 W. 45th St., Austin, Texas 78756 voice 512.206.9315 fax: 512.206.9264 http://www.tsbvi.edu/ "We shape our tools and thereafter our tools shape us."
