RDFa Working Group
This Working Group has been closed on the 2015-03-27.
For further discussions on the future evolution of RDFa, please consider
using the public-rdfa@w3.org mailing list (see public
archives). You can also use the Errata
(Wiki) page to record errors, typos, etc. that may
be considered by a future working group.
The mission
of the RDFa Working Group, formerly the W3C RDF Web Application Working
Group and part of the Semantic Web
Activity, is to support the developing use of RDF for embedding
and handling structured data in Web documents in general. The Working
Group will publish W3C Recommendations to define HTML5 and XHTML5 as
Host Languages for RDFa
1.1 Core.
The RDFa
Working Group Charter shows what the W3C has asked this working
group to do.

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.

Patent Policy (5 February 2004 Version). To promote the widest
adoption of Web standards, W3C seeks to issue Recommendations that can
be implemented, according to this policy, on a Royalty-Free basis.

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.
