P-Plan documentation is released!

We are happy to announce that the Ontology for Provenance and Plans (P-Plan) specification is online: http://www.opmw.org/model/p-plan/.
P-plan is an extension of the PROV-O ontology created to represent the plans that guided the execution of scientific processes. P-Plan describes how the plans are composed and their correspondence to provenance records that describe the execution itself.
Take a look at the ontology here: http://www.opmw.org/p-plan.owl
