   740       <p>The PROV Ontology (PROV-O) expresses the PROV Data Model using 
   741 the OWL2 Web Ontology Language (OWL2). It provides a set of classes, 
   742 properties, and restrictions that can be used to represent and 
   743 interchange provenance information generated in different systems and 
   744 under different contexts. It can also be specialized to create new 
   745 classes and properties to model provenance information specific to 
   746 different domain applications.
   747 	  </p>
   748 
   749      <p style="text-align: center;">The OWL encoding of the PROV Ontology is available <a href="http://dvcs.w3.org/hg/prov/raw-file/cf7deb6c5f3e/ontology/ProvenanceOntology.owl">here</a>.

   777 <h2><span class="secno">1. </span>Introduction</h2>  
   778       <p>The PROV Ontology (PROV-O) defines the normative OWL2 Web Ontology Language encoding of the PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>].
   779  This document describes the set of classes, properties, and 
   780 restrictions that constitute the PROV Ontology. This ontology 
   781 specification provides the foundation to implement provenance 
   782 applications in different domains that can represent, exchange, and 
   783 integrate provenance information generated in different systems and 
   784 under different contexts. 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>],
   785  this document forms a framework for provenance information interchange 
   786 and management in domain-specific Web-based applications.
   787       </p>
   788 	  <p>
   789 		PROV-O conforms to the OWL-RL profile and is lightweight so that it 
   790 can be adopted in the widest range of applications. The PROV Ontology 
   791 classes and properties are defined such that they can not only be used 
   792 directly to represent provenance information, but also can be 
   793 specialized for modeling application-specific provenance details in a 
   794 variety of domains. Thus, the PROV Ontology is expected to be both 
   795 directly usable in applications as well as serve as a <i>reference model</i>
   796  for creating domain-specific provenance ontologies and thereby 
   797 facilitate interoperable provenance modeling. To demonstrate the use of 
   798 PROV-O classes and properties, this document uses an example provenance 
   799 scenario similar to the one introduced in the PROV-Primer [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-PRIMER">PROV-PRIMER</a></cite>]. PROV-O conforms to the OWL-RL profile and is lightweight so that it can be adopted in the widest range of applications.

   801 	  
   802 <!-- p>
   803 		Finally, this document describes the formal semantics of the PROV Ontology using the OWL2 semantics, [[!OWL2-DIRECT-SEMANTICS]], [[!OWL2-RDF-BASED-SEMANTICS]], and a set of provenance-specific inference rules. This is expected to support provenance implementations to automatically check for consistency of provenance information represented using PROV Ontology and explicitly assert implicit provenance knowledge.

   805 
   806       <p> The PROV Data Model [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>]
   807  introduces a minimal set of concepts to represent provenance 
   808 information in a variety of application domains. This document maps the 
   809 PROV Data Model to PROV Ontology using the OWL2 ontology language, which
   810  facilitates a fixed interpretation and use of the PROV Data Model 
   811 concepts based on the formal semantics of OWL2 [<cite><a class="bibref" rel="biblioentry" href="#bib-OWL2-RDF-BASED-SEMANTICS">OWL2-RDF-BASED-SEMANTICS</a></cite>]. 
   812 	  </p>
   813 
   814 	  <p> We briefly introduce some of the OWL2 modeling terms that will be used to describe the PROV Ontology. An OWL2 <i>instance</i>
   815  is an individual object in a domain of discourse, for example a person 
   816 named Alice or a car, and a set of individuals sharing a set of 
   817 additional characteristics is called a <i>class</i>. Person and Car are 
   818 examples of classes representing the set of individual persons and cars 
   819 respectively. The OWL2 object properties are used to link individuals, 
   820 classes, or create a property hierarchy. For example, the object 
   821 property "hasOwner" can be used to link car with person. The OWL2 
   822 datatype properties are used to link individuals or classes to data 
   823 values, including XML Schema datatypes [<cite><a class="bibref" rel="biblioentry" href="#bib-XMLSCHEMA-2">XMLSCHEMA-2</a></cite>].   
   824 	  </p>
   825 
   826 	  <p>The key words "<em class="rfc2119" title="must">must</em>", "<em class="rfc2119" title="must not">must not</em>", "<em class="rfc2119" title="required">required</em>", "<em class="rfc2119" title="shall">shall</em>", "<em class="rfc2119" title="shall not">shall not</em>", "<em class="rfc2119" title="should">should</em>", "<em class="rfc2119" title="should not">should not</em>", "<em class="rfc2119" title="recommended">recommended</em>",  "<em class="rfc2119" title="may">may</em>", and       "<em class="rfc2119" title="optional">optional</em>" in this document are to be interpreted as described in [<cite><a class="bibref" rel="biblioentry" href="#bib-RFC2119">RFC2119</a></cite>].</p>

   836 <h2><span class="secno">2. </span>PROV-O at a glance</h2>
   837 
   838       <p>PROV-O users may only need to use parts of the entire ontology,
   839  depending on their needs and according to how much detail they want to 
   840 include in their provenance information. For this, the PROV-O terms 
   841 (classes and properties) are grouped into four categories to provide an 
   842 incremental introduction to the ontology: Starting Point terms, Expanded
   843  terms, terms for Qualifying relationships, and terms for Collections.
   844       </p>
   845       <p><strong>Starting Point classes and properties</strong> provide 
   846 the basis for the rest of the PROV Ontology and thus it is recommended 
   847 that readers become comfortable with how to apply these terms before 
   848 continuing to the remaining categories. These terms are used to create 
   849 simple provenance descriptions that can be elaborated using terms from 
   850 other categories. The classes and properties in this category are listed
   851  below and are discussed in <a href="#description-starting-point-terms">Section 3.1</a>.</p>

  1256        <p>The Starting Point category is a small collection of classes 
  1257 and properties that can be used to create simple, initial provenance 
  1258 descriptions.
  1259          Three classes provide a basis for the rest of PROV-O:  
  1260        </p>
  1261          <ul>
  1262             <li> <a href="#Entity" class="qname">prov:Entity</a>: An entity is a thing one wants to provide provenance for. Things can be physical, digital, conceptual, or otherwise.
  1263             </li>
  1264             <li> <a href="#Activity" class="qname">prov:Activity</a>: An
  1265  activity is something that occurs over a period of time and acts upon 
  1266 or with entities. This action can take multiple forms: consuming, 
  1267 processing, transforming, modifying, relocating, using, generating, etc.
  1268             </li>
  1269             <li> <a href="#Agent" class="qname">prov:Agent</a>: An agent
  1270  bears some form of responsibility for an activity taking place. 
  1271 Further, an agent may act on behalf of another agent when involved with 
  1272 an activity.
  1273             </li>
  1274          </ul> 
  1275       <p>These three classes and the properties that relate them are illustrated in the following figure.
  1276       </p>
  1277 
  1278       <div style="text-align: center;">

  1284 
  1285          <p>
  1286          Entities are related to each other using derivation, which is used to 
  1287          specify that the creation/existence of an entity was influenced in some 
  1288          way by the consumption of another entity. 
  1289          An entity can be attributed to an agent to specify that the entity was 
  1290          generated by some activity that the agent in question was associated 
  1291          with.
  1292          </p>
  1293 
  1294          <p>
  1295          Activities may depend on each other. PROV-O distinguishes between two 
  1296          kinds of dependencies which are specified using the properties 
  1297          <a class="qname" href="#wasInformedBy">prov:wasInformedBy</a> and <a class="qname" href="#wasStartedByActivity">prov:wasStartedByActivity</a>. 
  1298          The first is used to specify that an activity used an entity that was 
  1299          generated by another activity, and the second is used to specify that an
  1300           activity was started or triggered by another activity.

  1397       activity <code>ex:aggregationActivity</code> used 
  1398       the entities <code>ex:crimeData</code> (a crime statistics dataset) and <code>ex:nationalRegionsList</code> (a list of national regions), and 
  1399       generated a new entity, <code>ex:aggregatedByRegions</code>, that aggregates the statistics in
  1400        <code>ex:crimeData</code> according to the regions in <code>ex:nationalRegionsList</code>. 
  1401       The <code>ex:aggregatedByRegions</code> entity was then used by the <code>ex:illustrationActivity</code> activity, 
  1402       to generate a new entity <code>ex:chart1</code> that depicts the aggregated statistics.
  1403       </p>
  1404 
  1405       <p> The example also states that the activity <code>ex:illustrationActivity</code> was 
  1406       informed by the activity <code>ex:aggregationActivity</code>. Indeed, the former used
  1407        the entity <code>ex:aggregatedByRegions</code>, which was generated by the latter.
  1408       </p>
  1409 
  1410       <p> Because the agent <code>ex:derek</code> was associated with the activities 
  1411       <code>ex:aggregationActivity</code> and <code>ex:illustrationActivity</code>, the entities 
  1412       generated by these activities, i.e., <code>ex:aggregatedByRegions</code> and <code>ex:chart1</code>, were 
  1413       attributed to him.

  1415 
  1416       <p>Finally, the example states that the agent <code>ex:derek</code> acted on behalf of the organization <code>ex:chartgen</code>.

  1436 
  1437 
  1438         <p>This section defines additional terms for describing provenance at a greater level of specificity in Agents (i.e., <a class="qname" href="#Person">prov:Person</a> or
  1439 		<a class="qname" href="#SoftwareAgent">prov:SoftwareAgent</a> and <a class="qname" href="#Organization">prov:Organization</a>) and entities 
  1440 		(<a class="qname" href="#specializationOf">prov:specializationOf</a> and <a class="qname" href="#AlternateOf">prov:AlternateOf</a>). 
  1441 		</p>
  1442 		<p>
  1443 		Additionally, some of these terms provide the means to assert extended details about the concepts introduced in section 3.1
  1444 		(<a class="qname" href="#wasStartedBy">prov:wasStartedBy</a> and (<a class="qname" href="#wasEndedBy">prov:wasEndedBy</a> in activities 
  1445 		 and <a class="qname" href="#Location">prov:Location</a> in entities).
  1446 		 
  1447 		Further annotations on provenance records can be done through <a class="qname" href="#Note">prov:Notes</a>, although we can group the provenance statements in 
  1448 		<a class="qname" href="#Account">prov:Accounts</a> in order to keep the record of the provenance metadata itself.
  1449 		</p>
  1450 		<p>
  1451 		The new terms in this section also facilitate the modeling of common provenance assertions related to web resources. 
  1452 		For example, different versions of a web page can be represented using the <a class="qname" href="#wasRevisionOf">prov:wasRevisionOf</a> 
  1453 		property, the <a class="qname" href="#hadOriginalSource">prov:hadOriginalSource</a> property can be used to reference the original source
  1454 		of information used in a web resource and users can quote existent entities using the <a class="qname" href="#wasQuotedFrom">prov:wasQuotedFrom</a> property. 
  1455 		For expressing the dependency between two different entities, users can assert the <a class="qname" href="#tracedTo">prov:tracedTo</a> property.

  1557 		   <p>
  1558 		   Agent <code>ex:derek</code>, acting again in behalf of the <code>ex:chartgenerators</code> organization, 
  1559 		   publishes a post about his recent changes to the aggregated file (<code>ex:aggregatedByRegions</code>).
  1560  He also provides the location for the crime file, so everyone knows the
  1561  content he has been browsing, 
  1562 		   and records the city where the publishing took place (Madrid). 
  1563 Since he is the one who started and ended the publishing activity (<code>ex:publicationActivity1123</code>), that information
  1564 		   is recorded as well. The post produced by <code>ex:derek</code> (<code>ex:post9821</code>) includes a permanent link where the content of the latest version is shown
  1565 		   (<code>ex:more-crime-happens-in-cities</code>) plus a snapshot of the content of the current version (<code>ex:postContent0</code>). Derek also adds additional metadata of the post, like the title.
  1566 		   </p>
  1567 		   <p>
  1568 		   However, inmediately after having published the post, Derek detects
  1569  a typo. He doesnt' want to record the activity that led to the new 
  1570 version, so he just creates a new version and 
  1571 		   summarizes the changes in a revision of the original post(<code>ex:post9821v1</code>). This revision is also a specialization of the original post, since it is a refined version. 
  1572 		   Thus, the location of the new revision has the same permalink, but a different url for its snapshot (<code>ex:postContent1</code>).
  1573 		   </p>
  1574 		   <p>
  1575 		   Shortly after Derek's post publication, ex:monica adapts the text for a wider audience in a new version (<code>ex:post9821v2</code>).
  1576  This version is an specialization of the original post,
  1577 		   and an alternate of the first version modified by Derek. Since the 
  1578 provenance produced by Derek and Monica is related to the same 
  1579 resources, the system
  1580 		   automatically groups it in the same <a class="qname" href="#Account">prov:Account</a> (<code>ex:accountPost</code>).

  1673        <h3><span class="secno">3.3 </span>Qualified Terms</h3>
  1674        <p>The classes and properties in the Qualified terms category are
  1675  for users who wish to provide additional details about the 
  1676 relationships between entities, activities, and agents. The terms in 
  1677 this category are the result of applying the <strong>Qualification Pattern</strong> to the simple relations available in the <a href="#prov-starting-point-owl-properties-at-a-glance">Starting Point</a> and <a href="#prov-expanded-owl-properties-at-a-glance">Expanded</a> categories.
  1678       </p>
  1679       <p>For example, Figure 2 illustrates the classes and properties needed to fulfill the qualification pattern for the <a href="#used" class="qname">prov:used</a> and <a href="#wasAssociatedWith" class="qname">prov:wasAssociatedWith</a> properties. While <a href="#qualifiedUsage" class="qname">prov:qualifiedUsage</a>, <a href="#Usage" class="qname">prov:Usage</a>, and <a href="#entity" class="qname">prov:entity</a> are used to qualify <span class="repeated">prov:used</span> relations, <a href="#qualifiedAssociation" class="qname">prov:qualifiedAssociation</a>, <a href="#Association" class="qname">prov:Association</a>, and <a href="#agent" class="qname">prov:agent</a> are used to qualify <span class="repeated">prov:wasAssociatedWith</span> relations. This pattern applies to the twelve other relations that can be qualified.
  1680       </p>
  1681       <p>In the example, the <span class="repeated">prov:qualifiedUsage</span> property parallels the <span class="repeated">prov:used</span> property, and references an instance of <span class="repeated">prov:Usage</span> that provides attributes of the <span class="repeated">prov:used</span> relation between the Activity and Entity. The <span class="repeated">prov:entity</span>
  1682  property is used to cite the Entity that was used by the Activity. In 
  1683 this case, the time that the Activity used the Entity is provided using 
  1684 the <span class="repeated">prov:atTime</span> property and a literal <span class="repeated">xsd:dateTime</span> value.
  1685       </p>
  1686       <p>Similarly, the <span class="repeated">prov:qualifiedAssociation</span> property parallels the <span class="repeated">prov:wasAssociatedWith</span> property, and references an instance of <span class="repeated">prov:Association</span> that provides attributes of the <span class="repeated">prov:wasAssociatedWith</span> relation between the Activity and Agent. The <span class="repeated">prov:agent</span>
  1687  property is used to cite the Agent that was involved in the Activity. 
  1688 In this case, the plan that the Agent used is provided using the <span class="repeated">prov:hadPlan</span> property and an instance of <span class="repeated">prov:Plan</span>.

  1936 
  1937 	<p> A <code><a href="#Collection" class="qname">prov:Collection</a></code> is an <code class="repeated">prov:Entity</code> that acts as a container to some members,
  1938 which are themselves entities.
  1939 Specifically, a collection is composed of set of key-value pairs, where a
  1940 literal key is used to identify a constituent entity within the collection. 
  1941 
  1942 To illustrate this, the example below describes a collection <code>:c1</code>
  1943 that has as members the two key value pairs <code>("k1", :e1)</code>
  1944 and <code>("k2", :e2)</code>.

  1971 <p>It is worth noting that <code>:c1</code> <em class="rfc2119" title="may">may</em> also
  1972 have other members (i.e. <code class="repeated">prov:knownMembership</code> is
  1973 not functional).  A collection <em class="rfc2119" title="may">may</em> be empty and thus not have any known
  1974 memberships, in which case it <em class="rfc2119" title="should">should</em> be described as an instance of the
  1975 subclass <a href="#EmptyCollection" class="qname"><code>prov:EmptyCollection</code></a>.
  1976 </p>
  1977 
  1978 	<p> To describe the provenance of a collection, PROV-O provides two
  1979 kinds of involvements: <code><a href="http://aquarius.tw.rpi.edu/prov-wg/qualifiedInsertion" class="qname">prov:qualifiedInsertion</a></code> is used to
  1980 describe that a collection was obtained from an existing collection by
  1981 <em>inserting</em> a set of key-value pairs.  <code><a href="http://aquarius.tw.rpi.edu/prov-wg/qualifiedRemoval" class="qname">prov:qualifiedRemoval</a></code> is used to specify
  1982 that a given collection was obtained from an existing collection by
  1983 <em>removing</em> a set of key-value pairs.  The example below specifies that
  1984 the collection <code>:c1</code> was obtained from the empty collection
  1985 <code>:c1</code> by <em>inserting</em> the key-value pairs <code>("k1",
  1986 :e1)</code> and <code>("k2", :e2)</code>.
