 		<p>In addition to RDF Semantics, the OWL2 semantics as described in [[!OWL2-DIRECT-SEMANTICS]], [[!OWL2-RDF-BASED-SEMANTICS]] are also applicable to PROV ontology. We consider the OWL2 RDF-Based Semantics (since it is a semantics superset of OWL2 Direct Semantics) and specifically the extension of the D-interpretation, which satisfies the constraints for rdf-interpretation, rdfs-interpretation (as defined in previous section), graphs with blank nodes, and interpretation defined for RDF datatypes (see Section 5.1 in RDF Semantics [[!RDF-MT]]). The OWL2 RDF-based semantics introduces the notion of "facets" to constrain datatypes, both the rdf:XMLLiteral defined in the RDF Semantics [[!RDF-MT]] and datatypes defined in the OWL2 Structural Specifications [[!OWL2-SYNTAX]]. The OWL2 RDF-based interpretation, also called <b>D-interpretation with facets</b> is a D-interpretation that also satisfies the OWL2 RDF-based semantics called "semantic constraints" (see Section 5 in OWL2 RDF-Based Semantics [[!OWL2-RDF-BASED-SEMANTICS]]).

 	<h3>Provenance-specific Entailments Supported by PROV Ontology</h3>
 	<p>The PROV-DM [[PROV-DM]] introduces a set of specific constraints applicable to PROV ontology. The following is a list of constraints that will be supported by the PROV ontology and any provenance application that uses the PROV ontology.</p>
