Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>] in the OWL2 Web Ontology Language (OWL2). The PROV ontology consists of a set of classes, properties, and restrictions that can be used to represent provenance information. The PROV ontology is specialized to create domain-specific provenance ontologies that model the provenance information specific to different applications. The PROV ontology supports a set of entailments based on OWL2 formal semantics and provenance specific inference rules. The PROV ontology is available for download as a separate OWL2 document.</p>

PROV Ontology Model (also PROV ontology) defines the normative modeling of the PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>] using the W3C OWL2 Web Ontology Language. This document specification describes the set of classes, properties, and restrictions that constitute the PROV ontology, which have been introduced in the PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>]. This ontology specification provides the foundation for implementation of provenance applications in different applications using the PROV ontology for representing, exchanging, and integrating provenance information. Together with the PROV Access and Query [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-PAQ">PROV-PAQ</a></cite>] and PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>], this document forms a framework for provenance information management in domain-specific Web-based applications.
</p>
<p>
- The PROV ontology classes and properties are defined such that they can be specialized for modeling application-specific provenance information in a variety of domains. Thus, the PROV ontology is expected to serve as a <i>reference model</i> for domain-specific provenance ontology and thereby facilitate consistent provenance interchange. This document uses an example <a href="http://dvcs.w3.org/hg/prov/raw-file/default/model/ProvenanceModel.html#a-file-scenario"> provenance scenario </a> introduced in the PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>] to demonstrate the specialization of PROV ontology.

<p> The PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>] introduces a minimal set of concepts to represent provenance information in a variety of application domains. This document maps the PROV Data Model to PROV Ontology using the OWL2 ontology language, which facilitates a fixed interpretation and use of the PROV Data Model concepts based on the formal semantics of OWL2 [<cite><a class="bibref" rel="biblioentry" href="#bib-OWL2-DIRECT-SEMANTICS">OWL2-DIRECT-SEMANTICS</a></cite>] [<cite><a class="bibref" rel="biblioentry" href="#bib-OWL2-RDF-BASED-SEMANTICS">OWL2-RDF-BASED-SEMANTICS</a></cite>].
</p>
<p>The PROV Ontology is not designed to be used directly in a domain application and its Classes and Properties represent "higher-level" or abstract level concepts that can be specialized further for representing domain-specific provenance information. We briefly introduce some of the OWL2 modeling terms that will be used to describe the PROV ontology. An OWL2 <i>instance</i> is an individual object in a domain of discourse, for example a person named Alice or a car, and a set of individuals sharing a set of common characteristics is called a <i>class</i>. Person and Car are examples of classes representing the set of individual persons and cars respectively. The OWL2 object properties are used to link individuals, classes, or create a property hierarchy. For example, the object property "hasOwner" can be used to link car with person. The OWL2 datatype properties are used to link individuals or classes to data values, including XML Schema datatypes [<cite><a class="bibref" rel="biblioentry" href="#bib-XMLSCHEMA-2">XMLSCHEMA-2</a></cite>].

<div class="note"> Since the above constraint defined in PROV-DM does not define how pe is linked to the derivation of e2 from e1, this constraint can be supported in the "opposite" direction in PROV-O. In other words, given e2 was generated at time instant t2 by pe and pe used e1 at time instant t1 and t1 is less than t2, then we can assert that wasDerivedFrom(e2, e1).
