HTML5 Jumps Off the Drawing Board
InformationWeek (03/29/08) Lee, Mike
The first public working draft of the HTML5 specification was announced by the World Wide Web Consortium in mid January, although this does not mean the W3C has abandoned XHTML 2.0, which is still being developed. "The HTML5 specification is a good step because it's a fairly realistic one," says Opera Software's Charles McCathie Nevile. "It doesn't aim to change the world in a radical way." Among HTML5's revisions are updates to simplify interactive Web development; header, footer, section, article, nav, and dialogue capabilities to more clearly split page sections; and a "canvas" with a corresponding 2D drawing application programming interface that supports dynamic graphics and animation on the spur of the moment. Components that HTML5 removes to eliminate usability problems include frames and framesets and most presentational attributes. HTML5 includes APIs that support direct provisions for audio and video, client-side persistent storage with both key/value and SQL database support, cross-document messaging, and offline-application, editing, drag-and-drop, and network APIs. HTML5 design principles focus on the support of existing content, compatibility, interoperability, universal access, and utility. The W3C expects the ratification of the full HTML5 recommendation in the third quarter of 2010, but Firefox, Opera, Internet Explorer, and Safari already offer pieces of support for the specification.
