HTML5: Microdata

The use of microdata (i.e. microformats) is being considered by the HTML community. A Draft Recommendation has just been released. That would mean it is not yet a standard, still open to comments. "Sometimes, it is desirable to annotate content with specific machine-readable labels, e.g. to allow generic scripts to provide services that are customised to the page, or to enable content from a variety of cooperating authors to be processed by a single script in a consistent manner."
