The mission of the Provenance Working Group, part of the Semantic Web Activity, is to support the widespread publication and use of provenance information of Web documents, data, and resources. The Working Group will publish W3C Recommendations that define a language for exchanging provenance information among applications.

Role of the OEG in the group

The OEG participates through Daniel Garijo who is involved in the weekly meetings and the development of the prov-o ontology, the primer and best practices documents.
