Two days after entering the Candidate Recommendation phase at World Wide Web Consortium (W3C), the RDFa 1.1 specification gathered two independent interoperable implementations. This means that RDFa 1.1 can advance to the next phases in the process of becoming an Official W3C Recommendation.
On March 13, RDFa 1.1 has become a Candidate Recommendation at W3C. If a certain specification has come to this phase, it means that all the technical work has been done. The purpose of having RDFa 1.1 for a certain period in the Candidate Recommendation phase was to establish a feature freeze on the technical work and to make a public call for software implementations of the specification. The period of the Candidate Recommendation phase ends on 30 April. The RDFa 1.1 specification should have had two independent and interoperable implementations by then, but this target was already reached after 48 hours. As the requirements set out by the Working Group are completed, the path is open for RDFa 1.1 to advance to the next phase and ultimately to become an official W3C Recommendation.
RDFa 1.1
RDFa adds a number of attribute-level extensions to XHTML to allow the embedding of structured data within Web documents. The specification consists of 3 documents that together outline the vision of RDFa in a variety of XML and HTML-based Web markup languages:
- RDFa Core 1.1: This document contains the core syntax and processing rules. It also explains how the language is intended to be used in XML document.
- RDFa Lite 1.1: This document contains a simplified subset of RDFa for inexperienced web authors.
- XHTML+RDFa 1.1: This document specifies the usage of RDFa in the XHTML markup language.
Together with Microformats and Microdata, RDFa is one of three competing specifications for adding machine-readable information to Web pages.
