"The most interesting thing will be what happens when those capabilities get into native HTML and what impact that has on the rich Internet development market," he said. Specific plug-in technologies are not supported on every platform, he said. "[Thusly], as a developer I might be more interested in writing HTML5," Hammond said.
The finalization of the specification will take some time, though. The plan is to have it available in a preliminary candidate recommendation form in the middle of 2009 and as a formal, final recommendation by September 2010, Connolly said. The process is lengthy because it takes time to get the technology to the point where Web authors can rely on it, he said. "It's up to each Web author to decide when he wants to implement new features," he noted.
Also new to HTML5 is it will be the first version implemented under the W3C Royalty-Free Patent Policy. This gives implementers greater assurance that standards can be implemented free of royalties, W3C said.
