- The PROV Ontology (also PROV-O) encodes the PROV Data 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.

- The PROV ontology classes and properties are defined such that they can not only be used directly to represent provenance information, but also can be specialized for modeling application-specific provenance details in a variety of domains. Thus, the PROV ontology is expected to be both directly usable in applications as well as serve as a <i>reference model</i> for creation of domain-specific provenance ontology and thereby facilitate interoperable provenance modeling. This document uses an example <a href="http://www.w3.org/TR/2011/WD-prov-dm-20111018/#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 use PROV-O classes and properties to model provenance information.

- <p>The PROV Ontology can be used directly in a domain application, though many domain applications may require specialization of PROV-O Classes and Properties 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>].

- <p>For example, the notion of "expressions" used in the PROV-DM map to RDF triple assertions in PROV-O. Similarly, the PROV-DM discusses the use of "Qualifier" to assert additional information about provenance terms. Following the general knowledge representation practices and OWL2 ontologies specifically, the PROV ontology specializes a given provenance term to create either a sub class or sub property to represent "additionally" qualified terms. Throughout this document, we explicitly state the difference, if any, between the PROV-DM term and PROV ontology term.

One may argue that given that an agent can be a process execution, a process execution, e.g., <i>pe1</i>, can be controlled by an agent <i>pe2</i>, which happens to be a process execution that is controlled by an agent <i>ag</i>, and that, therefore, <i>ag</i> (indirectly) controls <i>pe1</i>.

- <p> We briefly summarize the essential features of the RDF Semantics and refer to the RDF semantics [<cite><a class="bibref" rel="biblioentry" href="#bib-RDF-MT">RDF-MT</a></cite>] for the normative specification. The RDF Semantics uses model theory, with a notion of interpretation I defined over RDF (rdf-interpretation) or RDFS (rdfs-interpretation) vocabulary, for specifying the formal semantics of a RDF or RDFS graph [<cite><a class="bibref" rel="biblioentry" href="#bib-RDF-MT">RDF-MT</a></cite>]. The rdf-interpretation is an interpretation that satisfies a set of constraints called "<i>RDF semantic conditions</i>" and a set of "<i>RDF axiomatic triples</i>" (see Section 3.1 of RDF Semantics [<cite><a class="bibref" rel="biblioentry" href="#bib-RDF-MT">RDF-MT</a></cite>]). The rdfs-interpretation is defined over the additional terms in the RDFS vocabulary, including <i>rdfs:domain</i>, <i>rdfs:range</i>, <i>rdfs:Class</i>, <i>rdfs:subClassOf</i>, and <i>rdfs:subPropertyOf</i>.

</p>
<p>The rdfs-interpretation supports the following set of the entailment rules that are applicable to the PROV ontology (we do not discuss the simple RDF entailments):
</p>
<h4 id="rule-1">Rule 1</h4>
- <p>If a PROV ontology class X is defined to be <i>domain</i> of a PROV property, then an individual asserted as "subject" of that property in a RDF triple is an instance of the class X. (from rdf2 Rule defined in RDF Semantics)
+ <p>If a PROV ontology class X is defined to be <i>domain</i> of a PROV property, then an individual asserted as "subject" of that property in a RDF triple is an instance of the class X. (from rdf2 Rule defined in RDF Semantics)
</p>
<h4 id="rule-2">Rule 2</h4>
- <p>Similar to Rule 1, if a PROV ontology class Y is defined to be <i>range</i> of a PROV object property, then an individual asserted as "object" of that property in a RDF triple is an instance of the class Y. (from rdf3 Rule defined in RDF Semantics)
+ <p>Similar to Rule 1, if a PROV ontology class Y is defined to be <i>range</i> of a PROV object property, then an individual asserted as "object" of that property in a RDF triple is an instance of the class Y. (from rdf3 Rule defined in RDF Semantics)
</p>
<h4 id="rule-3">Rule 3</h4>
<p>Both the <code>rdfs:subClassOf</code> and <code>rdfs:subPropertyOf</code> are transitive properties, hence provenance assertions, in form of RDF triples, using a specialized sub class or sub property can be inferred to be true for their parent class or parent property. For example, in the provenance scenario, though alice and bob are asserted to be individuals of the class Journalist, we can infer that they are also individuals of the PROV ontology class Agent and Entity.
