Abstract
The PROV Ontology (PROV-O) expresses the PROV Data Model [PROV-DM] using the OWL2 Web Ontology Language (OWL2) [OWL2-OVERVIEW]. It provides a set of classes, properties, and restrictions that can be used to represent and interchange provenance information generated in different systems and under different contexts. It can also be specialized to create new classes and properties to model provenance information for different applications and domains. ThePROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.
The namespace for all PROV-O terms ishttp://www.w3.org/ns/prov#.
The OWL encoding of the PROV Ontology is availablehere.

1.Introduction
The PROV Ontology (PROV-O) defines the OWL2 Web Ontology Language encoding of the PROV Data Model [PROV-DM]. This document describes the set of classes, properties, and restrictions that constitute the PROV Ontology. This ontology specification provides the foundation to implement provenance applications in different domains that can represent, exchange, and integrate provenance information generated in different systems and under different contexts. Together with the PROV Access and Query [PROV-AQ] and PROV Data Model [PROV-DM], this document forms a framework for provenance information interchange in domain-specific Web-based applications.
PROV-O is a lightweight ontology that can be adopted in a wide range of applications. With the exception offive axioms, PROV-O conforms to the OWL-RL profile [OWL2-PRIMER]. 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 areference model for creating domain-specific provenance ontologies and thereby facilitates interoperable provenance modeling. To demonstrate the use of PROV-O classes and properties, this document uses an example provenance scenario similar to the one introduced in the PROV-Primer [PROV-PRIMER].
The PROV Data Model [PROV-DM] introduces a 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 [OWL2-OVERVIEW].
We briefly introduce some of the OWL2 modeling terms that will be used to describe the PROV Ontology. An OWL2instance is an individual object in a domain of discourse, for example a person named Alice or a car named KITT. A set of individuals sharing common characteristics constitutes aclass. 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 [XMLSCHEMA11-2].

2.PROV-O at a glance
This section is non-normative.
PROV-O users may only need to use parts of the entire ontology, depending on their needs and according to how much detail they want to include in their provenance information. For this, the PROV-O terms (classes and properties) are grouped into three categories to provide an incremental introduction to the ontology: Starting Point terms, Expanded terms, and terms for Qualifying relationships.
Starting Point classes and properties provide the basis for the rest of the PROV Ontology and thus it is recommended that readers become comfortable with how to apply these terms before continuing to the remaining categories. These terms are used to create simple provenance descriptions that can be elaborated using terms from other categories. The classes and properties in this category are listed below and are discussed inSection 3.1.
Expanded classes and properties provide additional terms that can be used to relate classes in the Starting Point category. The terms in this category are applied in the same way as the terms in the Starting Point category. Many of the terms in this category are subclasses or subproperties of those in the Starting Point category. The classes and properties in this category are listed below and are discussed inSection 3.2.
Qualified classes and properties provide elaborated information about binary relations asserted using Starting Point and Expanded properties. The terms in this category are applied using a pattern that differs from those in the Starting Point and Expanded categories. While the relations from the previous two categories are applied as direct, binary assertions, the terms in this category are used to provide additional attributes of the binary relations. The pattern used in this category allows users to provide elaborate details that are not available using only Starting Point and Expanded terms. The classes and properties in this category are listed below and are discussed inSection 3.3.
3.The PROV-O Ontology Description
This section introduces the terms in each of the following categories:
3.1Starting Point Terms
The Starting Point category is a small set of classes and properties that can be used to create simple, initial provenance descriptions. Three classes provide a basis for the rest of PROV-O:
- Anprov:Entity is a physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary.
- Anprov:Activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities.
- Anprov:Agent is something that bears some form of responsibility for an activity taking place, for the existence of an entity, or for another agent's activity.
The three primary classes relate to one another and to themselves using the properties shown in the following figure.
Activitiesstart andend at particular points in time (described using propertiesprov:startedAtTime andprov:endedAtTime, respectively) and during their lifespan canuse andgenerate a variety of Entities (described withprov:used andprov:wasGeneratedBy, respectively). For example, a blog writing activity may use a particular dataset and generate a bar chart. By expressing usage and generation, one can construct provenance chains comprising both Activities and Entities.
In addition, we can say that an Activityprov:wasInformedBy another Activity to provide some dependency information without explicitly providing the activities' start and end times. Aprov:wasInformedBy relation between Activities suggests that the informed Activity used an Entity that was generated by the informing Activity, but the Entity itself is unknown or is not of interest. So, theprov:wasInformedBy property allows the construction of provenance chains comprising only Activities.
Provenance chains comprising only Entities can be formed using theprov:wasDerivedFrom property. A derivation is a transformation of one entity into another. For example, if the Activity that created the bar chart is not known or is not of interest, then we can say that the bar chartprov:wasDerivedFrom the dataset. Arbitrary RDF properties can be used to describe the fixed aspects of an Entity that are interesting within a particular application (for example, the file size and format of the dataset, or the aspect ratio of the bar chart).
While the propertiesprov:used,prov:wasGeneratedBy,prov:wasInformedBy, andprov:wasDerivedFrom can be used to construct provenance chains among Activities and Entities, Agents may also be ascribed responsibility for any Activity or Entity within a provenance chain. An Agent's responsibility for an Activity or Entity is described using the propertiesprov:wasAssociatedWith andprov:wasAttributedTo, respectively. Agents can also be responsible for other Agents' actions. In this case of delegation, the influencing Agentprov:actedOnBehalfOf another Agent that also bears responsibility for the influenced Activity or Entity.
The properties rdf:type and rdfs:label are used to expressprov:type andprov:label, respectively.

The diagrams in this document depict Entities as yellow ovals,
Activities as blue rectangles, and Agents as orange pentagons.
The responsibility properties are shown in pink.
Example 1: The following PROV-O describes the resources involved when creating a chart about crime statistics. The example uses only Starting Point terms and serves as a basis for elaboration that will be described in subsequent sections. In the example, Derek performs an aggregation of some government crime data, grouping by national regions that are described in a separate dataset by a civil action group.
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .@prefix foaf: <http://xmlns.com/foaf/0.1/> .@prefix prov: <http://www.w3.org/ns/prov#> .@prefix : <http://example.org#> .:bar_chart a prov:Entity; prov:wasGeneratedBy :illustrationActivity; prov:wasDerivedFrom :aggregatedByRegions; prov:wasAttributedTo :derek;.:derek a foaf:Person, prov:Agent; foaf:givenName "Derek"; foaf:mbox <mailto:derek@example.org>; prov:actedOnBehalfOf :natonal_newspaper_inc;.:national_newspaper_inc a foaf:Organization, prov:Agent; foaf:name "National Newspaper, Inc.";.:illustrationActivity a prov:Activity; prov:used :aggregatedByRegions; prov:wasAssociatedWith :derek; prov:wasInformedBy :aggregationActivity;.:aggregatedByRegions a prov:Entity; prov:wasGeneratedBy :aggregationActivity; prov:wasAttributedTo :derek;.:aggregationActivity a prov:Activity; prov:startedAtTime "2011-07-14T01:01:01Z"^^xsd:dateTime; prov:wasAssociatedWith :derek; prov:used :crimeData; prov:used :nationalRegionsList; prov:endedAtTime "2011-07-14T02:02:02Z"^^xsd:dateTime;.:crimeData a prov:Entity; prov:wasAttributedTo :government;.:government a foaf:Organization, prov:Agent .:nationalRegionsList a prov:Entity; prov:wasAttributedTo :civil_action_group;.:civil_action_group a foaf:Organization, prov:Agent .
The example states that the agent:derek was associated with two activities::aggregationActivity and:illustrationActivity. The activity:aggregationActivity used the entities:crimeData (a crime statistics dataset) and:nationalRegionsList (a list of national regions), and generated a new entity,:aggregatedByRegions that aggregates the statistics in:crimeData according to the regions in:nationalRegionsList. The:aggregatedByRegions entity was then used by the:illustrationActivity activity, to generate a new entity:bar_chart that depicts the aggregated statistics.
The example also states that the activity:illustrationActivity was informed by the activity:aggregationActivity. Indeed, the former used the entity:aggregatedByRegions, which was generated by the latter.
Because the agent:derek was associated with the activities:aggregationActivity and:illustrationActivity, the entities generated by these activities, i.e.,:aggregatedByRegions and:bar_chart, were also attributed to him.
Finally, the example states that the agent:derek acted on behalf of the organization:national_newspaper_inc.

Example 1, showing how the three Starting Point classes relate.
The diagrams in this document depict Entities as yellow ovals, Activities as blue rectangles,
and Agents as orange pentagons. The responsibility properties are shown in pink.
3.2Expanded Terms
The terms introduced in this section provide additional ways to describe the provenance among Entities, Activities, and Agents. The additional terms are illustrated in the following figure and can be separated into five different categories.
Figure 3. The expanded terms build upon those in the
Starting Points section.
The diagrams in this document depict Entities as yellow ovals, Activities as blue rectangles, and Agents as orange pentagons.
The domain of
prov:atLocation (
prov:Activity or
prov:Entity or
prov:Agent or
prov:InstantaneousEvent) is not illustrated.
Thefirst category extends theStarting Point terms with subclasses, subproperties, and a superproperty.
Three subclasses of Agent (prov:Person,prov:Organization, andprov:SoftwareAgent) and three subclasses of Entity are provided (prov:Collection,prov:Bundle, andprov:Plan).
Aprov:Collection is an Entity that provides a structure (e.g. set, list, etc.) to some constituents (which are themselves Entities). Theprov:Collection class can be used to express the provenance of the collection itself: e.g. who maintained the collection, which members it contained as it evolved, and how it was assembled. Theprov:hadMember property is used to assert membership in a collection.
Aprov:Bundle is a named set of provenance descriptions, which may itself have provenance. The named set of provenance descriptions may be expressed as PROV-O or any other form. The subclass of Bundle that names a set of PROV-O assertions is not provided by PROV-O, since it is more appropriate to do so using other recommendations, standards, or technologies. In any case, a Bundle of PROV-O assertions is an abstract set of RDF triples, and adding or removing a triple creates a new distinct Bundle of PROV-O assertions.
Aprov:Plan is an entity that represents a set of actions or steps intended by one or more agents to achieve some goals.
More general and more specific properties are also provided by the expanded terms. More generally, the propertyprov:wasInfluencedBy is a superproperty that relates any influenced Entity, Activity, or Agent to any other influencing Entity, Activity, or Agent that had an effect on its characteristics. Three subproperties ofprov:wasDerivedFrom are also provided for certain kinds of derivation among Entities:prov:wasQuotedFrom cites a potentially larger Entity (such as a book, blog, or image) from which a new Entity was created by repeating some or all of the original,prov:wasRevisionOf indicates that the derived Entity contains substantial content from the original Entity (e.g., two editions of a book), andprov:hadPrimarySource cites a preceding Entity produced by some agent with direct experience and knowledge about the topic (such as a reading from a sensor, or a journal written during an historical event).
Thesecond category of expanded terms relates Entities according to their levels of abstraction, where some Entities may present more specific aspects than their more general counterparts. Whileprov:specializationOf links a more specific Entity to a more general one (e.g., today's BBC news home page versus BBC's news home page on any day),prov:alternateOf links Entities that present aspects of the same thing, but not necessarily the same aspects or at the same time (e.g., the serialization of a document in different formats or a backup copy of a computer file).
Thethird category of expanded terms allows further description of Entities. The propertyprov:value provides a literal value that is a direct representation of an entity. For example, theprov:value of a quote could be a string of the sentences stated, or theprov:value of an Entity involved in a numeric calculation could be the xsd:integer four. The propertyprov:atLocation can be used to describe theprov:Location of any Entity, Activity, Agent, orprov:InstantaneousEvent (i.e., the starting or ending of an activity or the generation, usage, or invalidation of an entity). The properties used to describe instances ofprov:Location are outside the scope of PROV-O; reuse of other existing vocabulary is encouraged.
Thefourth category of expanded terms describes the lifetime of an Entity beyond beinggenerated by an Activity andused by other Activities. For example, a painting could not have been displayed before it was painted, and it could not be sold after it was destroyed by fire. Similar to how Activities have start and end times, an Entity may be bound by points in time for which it was generated or is no longer usable.The propertiesprov:generatedAtTime andprov:invalidatedAtTime can be used to bound the starting and ending moments of an Entity's existence. The Activities that led to the generation or invalidation of an Entity can be provided usingprov:wasGeneratedBy andprov:wasInvalidatedBy, respectively.prov:generated andprov:invalidated are the inverses ofprov:wasGeneratedBy andprov:wasInvalidatedBy, respectively, and are defined to facilitate Activity-as-subject as well as Entity-as-subject descriptions. For more about inverses, see theAppendix B.
Thefifth category of expanded terms describes the lifetime of an Activity beyond its start and end times and predecessor Activities. Activities may also be started or ended by Entities, which are described using the propertiesprov:wasStartedBy andprov:wasEndedBy, respectively. Since Entities may start or end Activities, and Agents may be Entities, then Agents may also start or end Activities.
The following examples illustrate the expanded terms by elaborating thecrime chart example from the previous section. After aggregating the dataset and creating the chart, Derek published a post to exhibit his work.

Agent:derek, acting again on behalf of the:national_newspaper_inc organization, used the:postEditor tool to publish a post about his recent data analysis:aggregatedByRegions. The blog editing tool tracked Derek's actions as PROV-O assertions and published them as a Bundle (the current file<>). The tool recorded that:derek started and ended the publishing activity (:publicationActivity1123) that generated the post:post9821v1. The post included a permanent link where the content of the latest version is available (:more-crime-happens-in-cities) in addition to a textual snapshot of the current version (using prov:value). Derek also included additional domain-specific descriptions of the post, such as its title.
Shortly after publishing the post, Derek noticed a typographical error in his narrative. Because the fix would be minimal, he did not record the activity that led to the new version. Instead, he related the new version (:post9821v2) as a revision of the previous (:post9821v1). Since both versions of the blog are forms of the long-standing blog permalink:more-crime-happens-in-cities, the revisions are alternates of one another and each is aprov:specializationOf of:more-crime-happens-in-cities.

Example 2, where Derek
published two versions of a blog for the National Newspaper, Inc.
The diagrams in this document depict Entities as yellow ovals, Activities as blue rectangles,
and Agents as orange pentagons. The responsibility properties are shown in pink.
Shortly after Derek published his blog post, Monica adapted the text for a wider audience in a new post (:post9822). This rewrite is an alternate, abbreviated view of the same topic that Derek wrote about and was created from his original text. Since the provenance produced by the activities of Derek and Monica corresponded to different user views, the system automatically published it in a differentprov:Bundle. The tool also asserted provenance about the bundle that it produced (e.g., the date of creation, its creator, and the fact that it Derek's bundle was used). Because a bundle is a kind of entity, all provenance assertions that can be made about entities can also be made about bundles. The use of bundles enables the creation of provenance of provenance.

After some time, John wrote his own conclusions in his own post (:post19201) quoting the previous two posts. Each quote that John makes (:quote_from_monica and:quote_from_derek) is a new entity derived from the previous blogs and is annotated with the time that the quote was taken. The provenance of John's blog notes that his post is the result of the quotes that he took from Derek and Monica. The blog post is also derived from Derek's:aggregatedByRegions dataset because John inspected it and found a concern that he discusses in his blog. All the provenance statements related to John's post are grouped in a newprov:Bundle.

Unfortunately, there was a problem in the servers where:post19201 was being stored, and all the data related to the post was lost permanently. Thus, the system invalidated the entity automatically and notified John about the error.

3.3Qualified Terms
The Qualified Terms category is the result of applying theQualification Pattern [LD-Patterns-QR] to the simple (unqualified) relations available in theStarting Point andExpanded categories. The terms in this category are for users who wish to provide further details about the provenance-related influence among Entities, Activities, and Agents.
The Qualification Pattern restates an unqualified influence relation by using an intermediate class that represents the influence between two resources. This new instance, in turn, can be annotated with additional descriptions of the influence that one resource had upon another. The following two tables list the influence relations that can be qualified using the Qualification Pattern, along with the properties used to qualify them. For example, the second row of the first table indicates that to elaborate how anprov:Activityprov:used a particularprov:Entity, one creates an instance ofprov:Usage that indicates the influencing entity with theprov:entity property. Meanwhile, the influencedprov:Activity indicates theprov:Usage with the propertyprov:qualifiedUsage. The resulting structure that qualifies the an Activity's usage of an Entity is illustrated inFigure 4a below.
SevenStarting Point relations can be further described using the Qualification Pattern. They are listed in the following normative table.
SevenExpanded relations can be further described using the Qualification Pattern. They are listed in the following normative table.
The qualification classes and properties shown in the previous two tables can also be found in the normativecross reference in the next section of this document. All influence classes (e.g.prov:Association,prov:Usage) are extensions ofprov:Influence and eitherprov:EntityInfluence,prov:ActivityInfluence, orprov:AgentInfluence, which determine the property used to cite the influencing resource (eitherprov:entity,prov:activity, orprov:agent, respectively). Becauseprov:Influence is a broad relation, its most specific subclasses (e.g.prov:Communication,prov:Delegation,prov:End,prov:Revision, etc.) should be used when applicable.
Example 6:
For example, given the unqualified statement:
:e1 a prov:Entity; prov:wasGeneratedBy :a1;.:a1 a prov:Activity .
One can find thatprov:wasGeneratedBy can be qualified using the qualification propertyprov:qualifiedGeneration, the classprov:Generation (a subclass ofprov:ActivityInfluence), and the propertyprov:activity. From this, the influence relation above can be restated with thequalification pattern as:
Example 7:
:e1 a prov:Entity; prov:wasGeneratedBy :a1; prov:qualifiedGeneration :e1Gen; # Add the qualification..:e1Gen a prov:Generation; prov:activity :a1; # Cite the influencing Activity. ex:foo :bar; # Describe the Activity :a1's influence upon the Entity :e1..:a1 a prov:Activity .
The asserter can thus attach additional properties to:e1Gen to describe the generation of:e1 by:a1.
As can be seen in this example, qualifying an influence relation provides a second form (e.g.:e1 prov:qualifiedGeneration :e1Gen) to express an equivalent influence relation (e.g.:e1 prov:wasGeneratedBy :a1). It is correct and acceptable for an implementer to use either qualified or unqualified forms as they choose (or both), and a consuming application should be prepared to recognize either form. Consuming applicationsshould recognize both qualified and unqualified forms, and treat the qualified form as implying the unqualified form. Because the qualification form is more verbose, the unqualified form should be favored in cases where additional properties are not provided. When the qualified form is expressed, including the equivalent unqualified form can facilitate PROV-O consumption, and is thus encouraged.
In addition to the previous two tables,Figure 4 illustrates the classes and properties needed to apply the qualification pattern to ten of the fourteen qualifiable influence relations. For example, whileprov:qualifiedUsage,prov:Usage, andprov:entity are used to qualifyprov:used relations,prov:qualifiedAssociation,prov:Association, andprov:agent are used to qualifyprov:wasAssociatedWith relations. This pattern applies to the twelve other influence relations that can be qualified.
In subfigurea theprov:qualifiedUsage property parallels theprov:used property and references an instance ofprov:Usage, which in turn provides attributes of theprov:used relation between the Activity and Entity. Theprov:entity property is used to cite the Entity that was used by the Activity. In this case, the time that the Activity used the Entity is provided using theprov:atTime property and a literalxsd:dateTime value. Theprov:atTime property can be used to describe anyprov:InstantaneousEvent (includingprov:Start,prov:Generation,prov:Usage,prov:Invalidation, andprov:End).
Similarly in subfigurej, theprov:qualifiedAssociation property parallels theprov:wasAssociatedWith property and references an instance ofprov:Association, which in turn provides attributes of theprov:wasAssociatedWith relation between the Activity and Agent. Theprov:agent property is used to cite the Agent that influenced the Activity. In this case, the plan of actions and steps that the Agent used to achieve its goals is provided using theprov:hadPlan property and an instance ofprov:Plan. Further, theprov:hadRole property andprov:Role class can be used to describe the function that the agent served with respect to the Activity. Bothprov:Plan andprov:Role are left to be extended by applications.

The following two examples show the result of applying the Usage and Association patterns to the chart-making example fromSection 3.1.
Example 8:
Qualified Usage
Theprov:qualifiedUsage property parallels theprov:used property to provide an additional description to:illustrationActivity. The instance ofprov:Usage cites the data used (:aggregatedByRegions) and the time the activity used it (2011-07-14T03:03:03Z).
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .@prefix prov: <http://www.w3.org/ns/prov#> .@prefix : <http://example.org#> .:illustrationActivity a prov:Activity; ## Using Starting Point terms, prov:used :aggregatedByRegions; ## the illustration activity used the aggregated data (to create the bar chart)..:aggregatedByRegions a prov:Entity .:illustrationActivity prov:qualifiedUsage [ ## Qualify how the :illustrationActivity a prov:Usage; ## used prov:entity :aggregatedByRegions; ## the Entity :aggregatedByRegions prov:atTime "2011-07-14T03:03:03Z"^^xsd:dateTime; ## Qualification: The aggregated data was used ## at a particular time to create the bar chart.. ];.
Example 9:
Qualified Association
Theprov:qualifiedAssociation property parallels theprov:wasAssociatedWith property to provide an additional description about the:illustrationActivity that Derek influenced. The instance ofprov:Association cites the influencing agent (:derek) that followed the instructions (:tutorial_blog). Further, Derek served the role of:illustrationist during the activity.
@prefix prov: <http://www.w3.org/ns/prov#> .@prefix : <http://example.org#> .:illustrationActivity a prov:Activity; ## Using Starting Point terms, prov:wasAssociatedWith :derek; ## the illustration activity was associated with Derek in some way..:derek a prov:Agent .:illustrationActivity prov:qualifiedAssociation [ ## Qualify how the :illustrationActivity a prov:Association; ## was associated with prov:agent :derek ## the Agent Derek. prov:hadRole :illustrationist; ## Qualification: The role that Derek served. prov:hadPlan :tutorial_blog; ## Qualification: The plan (or recipe, instructions) ## that Derek followed when creating the graphical chart. ];.:tutorial_blog a prov:Plan, prov:Entity .:illustrationist a prov:Role .
This section finishes with two more examples of qualification as applied to the chart-making example fromSection 3.1.
Example 10:
Qualified Generation
Theprov:qualifiedGeneration property parallels theprov:wasGeneratedBy property to provide an additional description to:bar_chart. The instance ofprov:Generation cites the time (2011-07-14T15:52:14Z) that the activity (:illustrationActivity) generated the chart (:bar_chart).
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .@prefix prov: <http://www.w3.org/ns/prov#> .@prefix : <http://example.org#> .:bar_chart a prov:Entity; ## Using Starting Point terms, prov:wasGeneratedBy :illustrationActivity; ## the chart was generated in an illustration activity..:illustrationActivity a prov:Activity .:bar_chart prov:qualifiedGeneration [ ## Qualify how the :bar_chart a prov:Generation; ## was generated by prov:activity :illustrationActivity; ## the Activity :illustrationActivity. prov:atTime "2011-07-14T15:52:14Z"^^xsd:dateTime; ## Qualification: The Activity generated ## the bar_chart at a particular time. ];.
Example 11:
Qualified Derivation
Theprov:qualifiedDerivation property parallels theprov:wasDerivedFrom property to provide an additional description to:bar_chart. The instance ofprov:Derivation cites the activity (:illustrationActivity) and the Usages and Generations that the activity conduced to create the:bar_chart.
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .@prefix prov: <http://www.w3.org/ns/prov#> .@prefix : <http://example.org#> .:bar_chart a prov:Entity; ## Using Starting Point terms, prov:wasDerivedFrom :aggregatedByRegions; ## the chart was derived from the aggregated dataset..:aggregatedByRegions a prov:Entity .:bar_chart prov:qualifiedDerivation [ ## Qualify a prov:Derivation; ## how :bar_chart was derived from prov:entity :aggregatedByRegions; ## the dataset Entity :aggregatedByRegions. prov:hadActivity :aggregating_activity; ## Qualification: The activity that derived the :bar_chart. prov:hadUsage :use_of_aggregatedData; ## Qualification: How the activity used :aggregatedByRegions. prov:hadGeneration :generation_of_bar_chart; ## Qualification: How the activity generated the :bar_chart. ];.
4.Cross reference for PROV-O classes and properties
This section provides details for each class and property defined by the PROV Ontology, grouped by the categories described above:
The superscriptsop anddp denote that a property is an OWLobject property ordata property, respectively.
Each PROV-O term in this cross reference links to the corresponding PROV-DM concept. The PROV-DM's tableCross-References to PROV-O and PROV-N provides an overview of the correspondences between PROV-O and PROV-DM.
The qualification classes and properties shown inTable 2 andTable 3 of the previous section can also be found in each entry of this cross reference. If the property can be qualified, thecan be qualified with header indicates the qualifying property and influence class that should be used. Conversely, thequalifies headers in the listings for qualification terms indicate the unqualified property that they qualify. In the OWL file itself, the annotation propertiesprov:qualifiedForm andprov:unqualifiedForm provide the same linkages between the unqualified properties and their qualifiying terms.
Most examples shown in this cross reference are encoded using the Turtle RDF serialization. When it is convenient to do so (e.g., when an example describes aprov:Bundle), it may use the [TRIG] syntax. Although this document does not specify how to encode Bundles in RDF, TriG's named graph construct is used only to illustrate the concept of creating a named set of PROV assertions. Note thatall examples are non-normative.

IRI:http://www.w3.org/ns/prov#hadPrimarySource
A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic's study, without benefit from hindsight.Because of the directness of primary sources, they 'speak for themselves' in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated.A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application's domain.

Because prov:Influence is a broad relation, its most specific subclasses (e.g. prov:Communication, prov:Delegation, prov:End, prov:Revision, etc.) should be used when applicable.
An instance of prov:Influence provides additional descriptions about the binary prov:wasInfluencedBy relation from some influenced Activity, Entity, or Agent to the influencing Activity, Entity, or Agent. For example, :stomach_ache prov:wasInfluencedBy :spoon; prov:qualifiedInfluence [ a prov:Influence; prov:entity :spoon; :foo :bar ] . Because prov:Influence is a broad relation, the more specific relations (Communication, Delegation, End, etc.) should be used when applicable.

IRI:http://www.w3.org/ns/prov#Start
Start is when an activity is deemed to have been started by an entity, known as trigger. The activity did not exist before its start. Any usage, generation, or invalidation involving an activity follows the activity's start. A start may refer to a trigger entity that set off the activity, or to an activity, known as starter, that generated the trigger.

IRI:http://www.w3.org/ns/prov#PrimarySource
A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic's study, without benefit from hindsight.Because of the directness of primary sources, they 'speak for themselves' in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated.A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application's domain.

A plan is an entity that represents a set of actions or steps intended by one or more agents to achieve some goals.

There exist no prescriptive requirement on the nature of plans, their representation, the actions or steps they consist of, or their intended goals. Since plans may evolve over time, it may become necessary to track their provenance, so plans themselves are entities. Representing the plan explicitly in the provenance can be useful for various tasks: for example, to validate the execution as represented in the provenance record, to manage expectation failures, or to provide explanations.

IRI:http://www.w3.org/ns/prov#Delegation
Delegation is the assignment of authority and responsibility to an agent (by itself or by another agent) to carry out a specific activity as a delegate or representative, while the agent it acts on behalf of retains some responsibility for the outcome of the delegated work.For example, a student acted on behalf of his supervisor, who acted on behalf of the department chair, who acted on behalf of the university; all those agents are responsible in some way for the activity that took place but we do not say explicitly who bears responsibility and to what degree.

IRI:http://www.w3.org/ns/prov#InstantaneousEvent
The PROV data model is implicitly based on a notion of instantaneous events (or just events), that mark transitions in the world. Events include generation, usage, or invalidation of entities, as well as starting or ending of activities. This notion of event is not first-class in the data model, but it is useful for explaining its other concepts and its semantics.

An instantaneous event, or event for short, happens in the world and marks a change in the world, in its activities and in its entities. The term 'event' is commonly used in process algebra with a similar meaning. Events represent communications or interactions; they are assumed to be atomic and instantaneous.

IRI:http://www.w3.org/ns/prov#qualifiedPrimarySource
A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic's study, without benefit from hindsight.Because of the directness of primary sources, they 'speak for themselves' in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated.A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application's domain.

IRI:http://www.w3.org/ns/prov#atTime
The PROV data model is implicitly based on a notion of instantaneous events (or just events), that mark transitions in the world. Events include generation, usage, or invalidation of entities, as well as starting or ending of activities. This notion of event is not first-class in the data model, but it is useful for explaining its other concepts and its semantics.

4.4Term Index
The PROV-O terms in this cross reference are shown below alphabetically, along with their entry number.
A.PROV-O OWL Profile
This section is non-normative.
To encourage widespread adoption, PROV-O's design is intentionally minimal and lightweight. Because the OWL 2 RL profile is aimed at RDF applications that require scalable reasoning without sacrificing too much expressive power [OWL2-PRIMER], it served as a baseline for all axioms included in PROV-O. The PROV-O axioms that do not suit the OWL 2 RL profile are listed inTable 5. All five use an anonymousclass union for the domain or range of a property, while OWL 2 RL requires the classes to be explicitly named. Although introducing "placeholder" classes would have suited the OWL 2 RL profile, these additional "abstract" classes would have been irrelevant to the modeling of provenance information, increased the size of PROV-O unnecessarily, and exposed a potential to confuse users. All five axioms listed in the following tableuse a non-superclass expression in a position that requires a superclass expression and do not conform to the OWL 2 RL Profile.
Table 5: All OWL Axioms in PROV-O that do not conform to the OWL-RL profile.| Non OWL-RL PROV-O Axiom |
|---|
| prov:atLocation rdfs:domain[ owl:unionOf (prov:Activity prov:Agent prov:Entity prov:InstantaneousEvent) ] |
| prov:wasInfluencedBy rdfs:domain[ owl:unionOf (prov:Activity prov:Agent prov:Entity) ] |
| prov:wasInfluencedBy rdfs:range[ owl:unionOf (prov:Activity prov:Agent prov:Entity) ] |
| prov:hadActivity rdfs:domain[ owl:unionOf (prov:Delegation prov:Derivation prov:Start prov:End) ] |
| prov:hadRole rdfs:domain[ owl:unionOf (prov:Association prov:InstantaneousEvent) ] |
To provide guidance for OWL 2 RL environments that ignore the union domain axioms, some property domains or ranges have also been defined with the closest common superclass for the classes in the union, as shown in the following table.
Multiple RDFS domains and ranges [RDF-SCHEMA] for a property areinterpreted as an intersection, and thus the above do not provide any additional information in an OWL 2 DL or OWL 2 Full profile, which also understands the unions. The more general domain should not be interpreted as saying, e.g., "prov:hadActivity can be used with anyprov:Influence", but as "Anything usingprov:hadActivity is (at least) a prov:Influence".
B.Names of inverse properties
To maximize interoperability, PROV-O intentionally avoids defining too many properties' inverses. In fact, it only defines two (prov:generated andprov:invalidated). When all inverses are defined for all properties, modelers may choose from two logically equivalent properties when making each assertion. Although the two options may be logically equivalent, developers consuming the assertions may need to exert extra effort to handle both (e.g., by either adding an OWL reasoner or writing code and queries to handle both cases). This extra effort can be reduced by preferring one inverse over another.
For example, the first PROV-O statement (below) could just as easily be asserted as the second statement. But if a client queries usingprov:wasDerivedFrom when:hadDerivation was used in the assertion, no results will be returned unless OWL reasoning is applied (or the size of the query is doubled).
<http://www.w3.org/TR/prov-o/> prov:wasDerivedFrom <http://www.w3.org/TR/prov-dm/> . # These two statements are equivalent if prov:wasDerivedFrom is an inverse of :hadDerivation. # But extra effort is required to handle both cases (if one is not already using OWL reasoning). # We cannot assume that everybody is using OWL reasoning. # We do not want people to write more code and query than necessary.<http://www.w3.org/TR/prov-dm/> :hadDerivation <http://www.w3.org/TR/prov-o/> .
So, PROV-O avoids this situation by encouraging modelers to use one property instead of its inverse; the preferred property to use is the one defined in the PROV-O ontology. Those asserting and querying for the preferred property avoid the need for OWL reasoning, additional code, and larger queries while maintaining the same level of interoperability.
However, theabsence of defined inverses can lead to adifferent risk to interoperability. Because modelers are free to create their own properties to suit their needs, they may be motivated to assert the inverse of any PROV-O property defined herein.
For example, since PROV-O does not define the inverse ofprov:wasDerivedFrom, and if three developers would rather model their assertions in the opposite direction, the following set of assertions might be found in the future web of provenance. These assertions are not in an interoperable form without the use of an OWL reasoner, additional code, or larger queries.
# If PROV-O's properties' inverses are not defined, modelers may be motivated to introduce their own inverse property name.# The following three statements are equivalent if their predicates are all inverses of prov:wasDerivedFrom.<http://www.w3.org/TR/prov-dm/> my:hadDerivation <http://www.w3.org/TR/prov-o/> .<http://www.w3.org/TR/prov-dm/> your:ledTo <http://www.w3.org/TR/prov-o/> .<http://www.w3.org/TR/prov-dm/> their:derivedTo <http://www.w3.org/TR/prov-o/> .
To balance these two interoperability risks, this document reserves the names of the PROV-O inverses. The name of a property's inverse is determined by appending the value of itshttp://www.w3.org/ns/prov#inverse annotation to the PROV namespace (http://www.w3.org/ns/prov#). Modelers wishing to use inverses of the properties defined by PROV-Oshould use those reserved by this document.
For example, the same three modelers above that definedmy:hadDerivation,your:ledTo, andtheir:derivedTo should instead look for thehttp://www.w3.org/ns/prov#inverse annotation onprov:wasDerivedFrom to determine that they should use the propertyhttp://www.w3.org/ns/prov#hadDerivation.
@prefix prov: <http://www.w3.org/ns/prov#> .# Each PROV-O property is annotated with the local name of its inverse.prov:wasDerivedFrom a owl:ObjectProperty; rdfs:isDefinedBy <http://www.w3.org/ns/prov#>; prov:inverse "hadDerivation"; rdfs:domain prov:Entity; rdfs:range prov:Entity;.# Instead of defining their own, modelers should use the# recommended inverse local name within the PROV namespace:<http://www.w3.org/TR/prov-dm/> prov:hadDerivation <http://www.w3.org/TR/prov-o/> .# Following this recommendation avoids a proliferation of inverse definitions, # while encouraging the use of one inverse over another.# This increases interoperability.
The following table lists the recommended inverse names that should be used if a modeler does not want to use the recommended PROV-O property. For convenience,this file lists the resulting inverse properties.
