W3C Prov

PROV is a set of recommended standards of the World Wide Web Consortium. These include its data model, an XML schema for that model, an OWL2 ontology mapping that model to RDF, and a mapping from that ontology to Dublin Core. It also includes a notation standard for provenance that is easy for humans to read; methods for accessing and querying prov; and a few other subspecifications.

The PROV standard defines a data model, serializations, and definitions to support the interchange of provenance information on the Web. Here provenance includes all "information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessments about its quality, reliability or trustworthiness".
