PROV released as W3C Recommendations
The Provenance Working Group was chartered to develop a framework for interchanging provenance on the Web. The Working Group has now published the PROV Family of Documents as W3C Recommendations, along with corresponding supporting notes. You can find a complete list of the documents in the PROV Overview Note.
PROV enables one to represent and interchange provenance information using widely available formats such as RDF and XML. In addition, it provides definitions for accessing provenance information, validating it, and mapping to Dublin Core.
