The W3C Provenance Working Group has published the First Public Working Draft of The PROV Data Model and Abstract Syntax Notation. PROV-DM is a core data model for provenance for building representations of the entities, people and processes involved in producing a piece of data or thing in the world. PROV-DM is domain-agnostic but with well-defined extensibility points allowing further domain-specific and application-specific extensions to be defined. It is accompanied by PROV-ASN, a technology-independent abstract syntax notation, which allows serializations of PROV-DM instances to be created for human consumption, which facilitates its mapping to concrete syntax, and which is used as the basis for a formal semantics. Two other documents, to be released shortly, 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.
