The mission of the RDFa
Working Group, formerly known as RDF Web Applications Working Group, is to
support the developing use of RDFa for embedding and handling structured data in
Web documents in general. In June 2012 W3C published the RDFa
Core 1.1, RDFa
Lite 1.1, and XHTML+RDFa
1.1 Recommendations; the RDFa Working Group is chartered to complete the
family of RDFa Specifications by finalizing the HTML+RDFa
1.1 specification (which is currently a Working Draft published by the HTML
Working Group) as a Recommendation. No substantive changes of the core RDFa
specifications are planned.
|End date||30 September 2013|
|Confidentiality||Proceedings are public|
|Initial Chair||Manu Sporny (Digital Bazaar, Inc.)|

|Usual Meeting Schedule||Teleconferences: every two weeks
Face-to-face: none planned.
RDFa 1.1 is specified as a core set of features (specified in the RDFa Core 1.1 Recommendation), and a lightweight subset of these features (specified in the RDFa Lite 1.1 Recommendation). This core can be adapted to the needs of particular Host Languages. The XHTML+RDFa 1.1 Recommendation describes the use of RDFa 1.1 with XHTML1.1 as a host language.
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 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.
The Working Group is chartered to define how RDFa Core 1.1 is to be used with HTML5 and XHTML5 as Host Languages. The processing rules defined for these host language would also apply to HTML4 and XHTML documents when interpreted according to the HTML 5 specification.
The Host Language specification may take into account some of the
structured data related mechanisms defined in HTML5, e.g., the interpretation of
datetime attribute to generate typed literals. The inclusion
of such mechanisms will depend on the available use cases and current RDFa
deployment (e.g., by schema.org usage or by the
Open Graph Protocol). Overall, adding markup beyond
what is defined in RDFa 1.1 Core is a non-goal.
The Working Group may issue Edited Recommendation for the RDFa
Core 1.1, RDFa
Lite 1.1, or XHTML+RDFa
1.1 documents if the errata
identified for these specifications make it necessary. The Working Group must
not add new features to these specifications.
|Note: Dates are based on a charter starting in September 2012. The group will document significant changes from this initial schedule on the group home page.|
|Specification||FPWD||LC||CR||PR||Rec or Edited
|HTML+RDFa 1.1 (Rec)||September 2012||January 2013||February 2013
||March 2013||May 2013|
“T” in this timeline is currently planned to be in September 2012; “T+n” means
“n” months later.
This schedule does not include Edited Recommendations for the existing RDFa 1.1
Recommendations, which will be issued if and when needed.
Furthermore, RDFa Working Group expects to follow these W3C Recommendations:
To be successful, the RDFa Working Group is expected to have 5 or more active participants for its duration. Effective participation in the RDFa Working Group is expected to consume one work day per week for each participant; two days per week for editors.
Participants are reminded of the Good Standing requirements of the W3C Process.
This group primarily conducts its work on the public mailing list firstname.lastname@example.org (with a publicly visible archive) .
Information about the group (deliverables, participants, teleconferences, etc.) is available from the RDFa Working Group home page.
As explained in the Process Document (section 3.3), this group will seek to make decisions when there is consensus. When the Chair puts a question and observes dissent, after due consideration of different opinions, the Chair should record a decision (possibly after a formal vote) and any objections, and move on.
This charter is written in accordance with Section 3.4, Votes of the W3C Process Document and includes no voting procedures beyond what the Process Document requires.
This Working Group operates under the W3C 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.

This charter for the RDFa Working Group has been created according to section 6.2 of the Process Document. In the event of a conflict between this document or the provisions of any charter and the W3C Process, the W3C Process shall take precedence.
The charter of the group has been extended on the 24th of January, 2012 to the 31st of July 2012 and then, subsequently, on the 6th of September, 2012.
