RDFa Core 1.1 and XHTML+RDFa 1.1 enter Second Last Call

The RDFa Working Group has published two Second Last Call Working Drafts today - RDFa Core 1.1 and XHTML+RDFa 1.1.

The first Last Call period for RDFa Core 1.1 and XHTML+RDFa 1.1 was started in late October 2010 and extended two times at the request of reviewers and comment submitters in order to get as wide a review as possible. There was input from members of the WHAT Working Group, the HTML Working Group, long-time RDFa Community participants, people working on behalf of large national governments, large and small commercial implementers, and RDFa Processor implementers.

Due to the quality of comments, the RDFa Working Group re-worked various specifications and tightened up features and language that could have caused implementations to diverge. Specifically, work to clarify the error reporting mechanism, generic XML+RDFa processing rules, the initial subject of a document, the further deprecation of xmlns:, and a Processor Graph vocabulary were completed.

The group is asking for comments on these two documents from the public until April 21st 2011. The Candidate Recommendation phase is next, during which the newly updated RDFa Test Suite will be used to test RDFa 1.1 implementations. Once there are two or more interoperable implementations, the RDFa specifications will proceed on toward the final W3C Recommended Specification.
