RDFa Working Group (original) (raw)
W3C Standards and Notes Published by this Working Group
RDFa 1.1 Core (REC)
RDFa Core is a specification for attributes to express structured data in any markup language. The embedded data already available in the markup language (e.g., HTML) can often be reused by the RDFa markup, so that publishers don't need to repeat significant data in the document content. The underlying abstract representation is RDF [RDF11-PRIMER], which lets publishers build their own vocabulary, extend others, and evolve their vocabulary with maximal interoperability over time. The expressed structure is closely tied to the data, so that rendered data can be copied and pasted along with its relevant structure.
RDFa 1.1 Lite (REC)
RDFa Lite is a minimal subset of RDFa, the Resource Description Framework in attributes, consisting of a few attributes that may be used to express machine-readable data in Web documents like HTML, SVG, and XML. While it is not a complete solution for advanced data markup tasks, it does work for most day-to-day needs and can be learned by most Web authors in a day.
HTML+RDFa 1.1 (REC)
This specification 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.
XHTML+RDFa 1.1 (REC)
RDFa Core 1.1 [RDFA-CORE] defines attributes and syntax for embedding semantic markup in Host Languages. This document defines one such Host Language. This language is a superset of XHTML 1.1 [XHTML11-2e], integrating the attributes as defined in RDFa Core 1.1. This document is intended for authors who want to create XHTML Family documents that embed rich semantic markup.
RDFa 1.1 Primer (NOTE)
This document provides only a Primer to RDFa 1.1. The complete specification of RDFa, with further examples, can be found in the RDFa 1.1 Core [rdfa-core], RDFa Lite [rdfa-lite], XHTML+RDFa 1.1 [xhtml-rdfa], and the HTML5+RDFa 1.1 [html-rdfa] specifications.

Schedule of Deliverables
- HTML +RDFa 1.1, Recommendation: This document will specify the behaviour of HTML5 and XHTML5 as host languages to RDFa 1.1 Core.
The group may also issue an Edited Recommendation for RDFa 1.1 Core, RDFa Lite 1.1 and XHTML+RDFa 1.1, folding in the possible editorial errata. No new functionality is planned on those documents.

History
The group operated, until September 2012, under the RDF Web Application Working Group Charter and completed the work described there. RDFa 1.1 was specified by the Working Group specified as a core set of features; this core can be adapted to the needs of particular Host Languages. Work on HTML5 as a Host Language for RDFa 1.1 has previously been pursued in the HTML Working Group, through an active cooperation with the RDFa (RDFWA) Working Group. The HTML+RDFa 1.1 specification was published as a Last Call Working Draft in May 2011, with a subsequent Working Draft published in March 2012. With the stronger interest in and expertise around the RDFa specifications now residing outside the HTML Working Group, this charter directs that the HTML+RDFa 1.1 specification be advanced to Recommendation by an RDFa Working Group with review by the HTML Working Group.
