This HTML Data Task Force considers [http://www.w3.org/TR/rdfa-core/ RDFa 1.1] and [http://dev.w3.org/html5/md/ microdata] as separate syntaxes, and conducts a technical analysis on the relationship between the two formats. The analysis discusses specific [[HTML Data Use Cases|use cases]] and provide guidance on [[Choosing an HTML Data Format|what format is best suited for what use cases]]. It further addresses the question [[Mixing HTML Data Formats|how different formats can be used]] within the same document when required and how data expressed in the different formats can be combined by consumers.
The task force MAY propose modifications in the form of [[HTML Data Improvements|bug reports and change proposals]] on the microdata and/or RDFa specifications, to help users to easily transition between the two syntaxes or use them together. As with all such comments, the ultimate decisions on implementing these will rest with the respective Working Groups.
Further, the Task Force should also produce a draft specifications of mapping algorithms from an [[Mapping Microdata to RDF|HTML+microdata content to RDF]], as well as a mapping of [[Mapping RDFa to JSON|RDFa to microdata's JSON format]]. These MAY serve as input documents to possible future recommendation track works. These mappings should be, if possible, generic, i.e., they should not be dependent on any particular vocabulary. A goal for these mappings should be to facilitate the use of both formats with the same vocabularies without creating incompatibilities.
The Task Force will also consider [[HTML Data Vocabularies|design patterns for vocabularies]], and provide guidance on how vocabularies should be shaped to be usable with both microdata and RDFa and potentially with microformats. These patterns MAY lead to change proposals of existing (RDF) vocabularies, and MAY result in general guidelines for the design of vocabularies for structured data on the web, building on existing community work in this area.
The Task Force liaises with the [http://www.w3.org/2001/sw/interest/webschema.html SWIG Web Schemas Task Force] to ensure that lessons from real-world experience are incorporated into the Task Force recommendations and that any best practices described by the Task Force are synchronised with real-world practice.
The Task Force conducts its work through the public-html-data-tf@w3.org mailing list (use [mailto:public-html-data-tf-request@w3.org?subject=subscribe this link] to subscribe or look at the [http://lists.w3.org/Archives/Public/public-html-data-tf/ public archives]), as well as on the [irc://irc.w3.org/html-data-tf #html-data-tf] channel of the (public) [irc://irc.w3.org W3C IRC] server. The Task Force maintains a list of [http://www.w3.org/2011/htmldata/track/issues issues] and [http://www.w3.org/2011/htmldata/track/actions actions] in the W3C tracker.
The Task Force is chaired by Jeni Tennison.
