HTML Data Task Force

HTML Data Task Force, chaired by Jeni Tennison.

Another opportunity to participate in important work at the W3C without a membership. The “details” of getting diverse formats to work together.

Close analysis may show the need for changes to syntaxes, etc., but as far as mapping goes, topic maps can take syntaxes as they are. Could be an opportunity to demonstrate working solutions for actual use cases.

From the wikipage:

This HTML Data Task Force considers RDFa 1.1 and microdata as separate syntaxes, and conducts a technical analysis on the relationship between the two formats. The analysis discusses specific use cases and provide guidance on what format is best suited for what use cases. It further addresses the question 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 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 HTML+microdata content to RDF, as well as a mapping of 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 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 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 this link to subscribe or look at the public archives), as well as on the #html-data-tf channel of the (public) W3C IRC server.
