The microdata section, currently listed as Section 5 Microdata does not enjoy broad consensus.
Per Manu Sprony:
"There will be a forthcoming HTML5+RDFa proposal that may either be published along-side the Microdata specification or in place of the Microdata specification. RDFa is a alternate technology that is currently published as a Recommendation via the W3C . An additional alternative that is being proposed is the removal of Microdata and RDFa from the HTML5 specification and the placement of each section into a separate specification that is implemented on top of the HTML5 standard."
In addition, the charter for the HTML WG mentions:
"The HTML WG is encouraged to provide a mechanism to permit independently developed vocabularies such as Internationalization Tag Set (ITS), Ruby, and RDFa to be mixed into HTML documents. Whether this occurs through the extensibility mechanism of XML, whether it is also allowed in the classic HTML serialization, and whether it uses the DTD and Schema modularization techniques, is for the HTML WG to determine."
The current microdata section precludes this Charter requirement.
Currently, issues of how to ensure that RDFa work with HTML are being discussed within the RDFa in XHTML Taskforce . The HTML WG should work with this group to ensure a consistent and unified approach to semantic metadata, as it relates to HTML 5.
