HTML5 Overview

An overview of all HTML5 standardization activities. For now, this content is also published on my blog by transforming it to HTML, but this may change over time.

HTML5 is more a movement (or maybe it's more appropriate to call it a brand) than it is a technology. it says "more power to the browser" and mostly means "more power to the browser as a programming platform". Given this focus of HTML5, it is surprisingly hard to find a good place where all the APIs under development are listed. This collection is an attempt to have all that information in one place. The current status captured on this page lists 79 current specifications and 5 expired specifications (84 total). Since the HTML5 landscape is changing fairly quickly, it is likely that some information on this page is outdated. If that is the case, please submit an issue or create a pull request. Thanks!

I am currently working on making this page as complete as the blog page.
