The RDFa Working Group today published three RDFa Recommendations. RDFa lets authors put machine-readable data in HTML documents. Using RDFa, authors may turn their existing human-visible text and links into machine-readable data without repeating content. Today’s publications were:
- HTML+RDFa 1.1, which defines rules and guidelines for adapting the RDFa Core 1.1 and RDFa Lite 1.1 specifications for use in HTML5 and XHTML5. The rules defined in this specification not only apply to HTML5 documents in non-XML and XML mode, but also to HTML4 and XHTML documents interpreted through the HTML5 parsing rules.
- The group also published two Second Editions for RDFa Core 1.1 and XHTML+RDFa 1.1, folding in the errata reported by the community since their publication as Recommendations in June 2012; all changes were editorial.
