W3C: Hold off on HTML5 in websites

Despite the hype, the HTML5 specification isn't yet ready due to interoperability issues, a W3C official says

HTML5, which updates the HTML specification to accommodate modern Web applications, has gained a lot of adherents in vendors like Microsoft, Google, and Apple. But the specification is plain not ready yet for deployment to websites, an official with the World Wide Web Consortium (W3C), which oversees HTML5, stressed this week.

"The problem we're facing right now is there is already a lot of excitement for HTML5, but it's a little too early to deploy it because we're running into interoperability issues," including differences between video on devices, said the official, Philippe Le Hegaret, W3C interaction domain leader. He is responsible for specifications like HTML and SVG (Scalable Vector Graphics).

"I don't think it's ready for production yet," especially since W3C still will make some changes on APIs, said Le Hegaret. "The real problem is can we make [HTML5] work across browsers and at the moment, that is not the case."

His advice on HTML5 was endorsed by industry analyst Al Hilwa of IDC.

"HTML 5 is at various stages of implementation right now through the Web browsers. If you look at the various browsers, most of the aggressive implementations are in the beta versions," Hilwa said. "IE9 (Internet Explorer 9), for example, is not expected to go production until close to mid-next year. That is the point when most enterprises will begin to consider adopting this new generation of browsers."

A vendor with an interest in the specification said some parts of HTML5 are ready and some are not.

"The point of HTML5 is this has been an ongoing effort for a while now and many parts of HTML5 are already in the wild," such as Canvas 2D capabilities and WebSockets, for communicating between browsers, said John Fallows, CTO of Kaazing, which makes a WebSockets gateway.
