From the W3C Web Site:
- The HTML Data Guide aims to help publishers and consumers of HTML data. With several syntaxes (microformats, microdata, RDFa) and vocabularies (schema.org, Dublin Core, microformat vocabularies, etc.) to choose from, it provides guidance on deciding what to choose in a way that meets the publisher’s or consumer’s needs.
- The Microdata to RDF describes processing rules that may be used to extract RDF from an HTML document containing microdata.
Both documents are Working Drafts, with the goal of publishing a final version as Interest Group Notes. Comments and feedbacks are welcome; please send them to the firstname.lastname@example.org mailing list.
