Versions
The latest version of the OWL ontology of PAV is always available from the PAV namespace:
| Namespace / OWL | Documentation |
|---|---|
| http://purl.org/pav/ | http://purl.org/pav/html |
Current version (v2.3):
| Namespace | versionIRI / OWL | Documentation |
|---|---|---|
| http://purl.org/pav/ | http://purl.org/pav/2.3 | http://purl.org/pav/2.3/html |
PAV follows the Semantic versioning rules. In particular, for say v2.1.0, we consider that:
- The major number (2.x.x) will increase if a change is breaking (such as removing or renaming a term). This will typically mean a new namespace.
- The minor number (x.1.x) will increase if a change is non-breaking, but adds new functionality (such as a new term or OWL import)
- The patch number (x.x.0) will increase if a change is a superficial bug-fix, such as changing typos or avoiding broken links.
Browse the SVN tags for individual patch releases.
Please note that the namespace is always http://purl.org/pav/ no matter which version of PAV 2.x is used.

# Lock down import to minor version 2.3
owl:imports <http://purl.org/pav/2.3> .
You may want to owl:imports either the namespace, http://purl.org/pav/, to always get the latest version (2.x.x), or a particular (minor or patch) versionIRI, as above, in order to lock down the version.
Note that for compatibility reasons, http://purl.org/pav/ returns the OWL as RDF/XML, but with Content-Type: application/xml in order to present a human-readable version (by XSLT) for browsers accessing the namespace URI. Some OWL tools might not accept this media type, in such cases the versionIRI like http://purl.org/pav/2.1 should be used instead, which return the ontology with Content-Type: application/rdf+xml
The versionIRI stated in the OWL files always return the latest patch version (ie. http://purl.org/pav/2.1 might serve 2.1.2) - the idea being that for most cases you would want patch updates.

Changes since v2.3.0:
- Re-added owl:equivalentProperty to PAV 1.2 properties (which where unintentionally removed in 2.3.0)

Changes since v2.2.0:
- Added more versioning properties: pav:hasVersion, pav:hasCurrentVersion, pav:hasEarlierVersion
- Subproperty relations to prov:alternateOf, prov:specializationOf, prov:generalizationOf, dct:hasVersion
- pav:previousVersion subproperty of pav:hasEarlierVersion
- Ontology metadata adds owl:priorVersion and new contributors.
- HTML: Updated diagram to show versioning

Changes since v2.1.2:
- DC Terms subproperties introduced:
- pav:authoredBy subproperty of dcterms:creator (creation of content)
- pav:createdBy subproperty of dcterms:creator (creation of representation)
- pav:contributedBy subproperty of dcterms:contributor (contribution of content)
- Avoids OWL import of http://purl.org/dc/terms/ - instead includes property definitions of the above
- Remaining properties still mapped to DCTerms in SKOS
- Description for date properties like pav:createdOn explain how to form an xsd:dateTime when time is unknown
- Descriptions have clarified intended functionality, e.g. pav:authoredBy indicate the last authoring date.
- Examples in descriptions further clarify the distinction between creation of representation and authoring of content.
- added owl:isDefinedBy http://purl.org/pav/ for PAV terms
- HTML documentation includes hierarchy of referenced PROV and DCTerms superproperties, but not their labels (making it clear that they are not defined by PAV), see for example prov:wasRevisionOf

Changes since v2.1.1:
- Misspelling in description of pav:createdBy - dct:createdBy changed to dct:creator
| Namespace | OWL | Documentation |
|---|---|---|
| http://purl.org/pav/ | http://purl.org/pav/2.1.1 | http://purl.org/pav/2.1.1/html |
Changes since v2.1.0:
- Link to overview diagram
- Modified descriptions for pav:importedFrom to clarify that the translated knowledge does not need to be complete
- Elaborated pav:createdWith, pav:derivedFrom, pav:importedBy, pav:retrievedBy
- A SKOS mapping for: dcterms; uses PAV in SKOS. This mapping is also described as a VoID dataset.

Changes since v2.0:
- Sub-property mapping to PROV-O. Note that PROV-O is not imported by PAV, so you may import http://www.w3.org/ns/prov#, for instance to get the inferred domains and ranges from PROV.
- Includes introduction about PAV ontology
- Descriptions of properties are elaborated with examples and relationships to each other
- Backward compatibility with PAV 1.2 terms indicated using owl:equivalentProperty (Note that the ontology itself is owl:incompatibleWith because several PAV 1 properties have changed names or are organized in a flatter hierarchy).
- pav:curates marked as deprecated, use its inverse pav:curatedBy
- owl:versionIRI does now does NOT end in a / - this is to avoid confusion between the versionIRI and the namespace (which stays unchanged).
- HTML representation of ontology (made using LODE)
- OWL-file includes a little XSLT stylesheet so that accessing http://purl.org/pav/ in a browser will give links to the above HTML documentation
- The individual URIs in the PAV namespace - like http://purl.org/pav/authoredBy - redirect to the OWL ontology
| Namespace | versionIRI / OWL | Documentation |
|---|---|---|
| http://purl.org/pav/ | http://purl.org/pav/2.0/ | http://purl.org/pav/2.0/html |
- Initial release independent from SWAN
- New namespace http://purl.org/pav/
- Terms removed: acceptedOn, authors, contributors, curators, importedFirstOn, importedLastOn, importedWithId, lastUpdateBy, publishedBy, publishedOn, sourceFirstAccessedOn, submittedBy, submittedOn
- Terms renamed: importedFromSource->importedFrom, versionNumber->version
- Terms added: authoredOn, contributedOn, createdAt, createdWith, curatedOn, curates, derivedFrom, lastRefreshedOn, providedBy, retrievedBy, retrievedFrom, retrievedOn, sourceAccessedBy
Note that during development of PAV 2.0, the ontology was split into three modules (with a common namespace): provenance authoring and versioning - but these modules were later merged to the single PAV ontology. For backward compatibility, these module versionIRIs now simply import the whole PAV ontology.
