The W3C Provenance Working Group recently announced that the group “has published a new Working Draft of The PROV Data Model and Abstract Syntax Notation. Provenance of information is crucial in deciding whether information is to be trusted, how it should be integrated with other diverse information sources, and how to give credit to its originators when reusing it. In an open and inclusive environment such as the Web, users find information that is often contradictory or questionable: provenance can help those users to make trust judgments. PROV-DM is a data model for provenance for building representations of the entities, people and activities involved in producing a piece of data or thing in the world.”

The document description explains, “This document is part of a set of specifications aiming to define the various aspects that are necessary to achieve the vision of inter-operable interchange of provenance information in heterogeneous environments such as the Web. This document defines the PROV-DM data model for provenance, accompanied with a notation to express instances of that data model for human consumption. Three other documents are: 1) a normative serialization of PROV-DM in RDF, specified by means of a mapping to the OWL2 Web Ontology Language; 2) the mechanisms for accessing and querying provenance; 3) a primer for the provenance data model.”
