Understanding PROV-O: A Comprehensive Overview

Learn about PROV-O, a lightweight ontology for provenance information exchange, based on the PROV-DM abstract model encoded in RDF. Discover key concepts, classes, properties, and namespaces. Get insights into starting points, expanded terms, and qualifying relationships. Explore extended terms, such as prov:atLocation and prov:value, along with the associated patterns like usage, association, and more.

  1. A Walk Through PROV-O

  2. Overview Part 1: Part 2: @timrdf http://bit.ly/prov-at-iswc-12

  3. <http://www.w3.org/ns/prov#> • A lightweight OWL-RL ontology • Provenance information interchange • “Simple” • Domain-neutral • Meant to be extended • Encodes PROV-DM’s “abstract model” in RDF • There are alternate encodings for XML, etc. @timrdf http://bit.ly/prov-at-iswc-12

  4. GET http://www.w3.org/ns/prov • Latest public draft: • curl -H "Accept: text/html" -L http://www.w3.org/ns/prov • curl -H "Accept: application/rdf+xml" -L http://www.w3.org/ns/prov • curl -H "Accept: text/turtle" -L http://www.w3.org/ns/prov • Latest editor’s draft: • http://bit.ly/prov-o-html • http://bit.ly/prov-o (OWL file) @timrdf http://bit.ly/prov-at-iswc-12

Namespaces • @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . • @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . • @prefix owl: <http://www.w3.org/2002/07/owl#> . • @prefix prov: <http://www.w3.org/ns/prov#> . • @prefix : <http://example.com/> . • “When in doubt, prefix.cc.” (e.g. http://prefix.cc/prov) @timrdf http://bit.ly/prov-at-iswc-12

  6. PROV-O at a glance • Starting point terms • The basis for the rest of the ontology • 3 classes + 9 properties • Simple, binary relations • Expanded terms • 7 classes + 18 properties • Adds subclasses and subproperties • Qualifyingrelationships • Elaborate 14 of the binary Starting and Expandedrelationships @timrdf http://bit.ly/prov-at-iswc-12

  7. Starting Points (Class View) The 3 main classes (Entity, Activity, Agent) can be organized by time or responsibility. @timrdf http://bit.ly/prov-at-iswc-12

  8. Starting Points (2D View) The 3 main classes (Entity, Activity, Agent) can be organized by time or responsibility. • actedOnBehalfOf • wasAttributedTo • wasAssociatedWith • used, wasDerivedFrom • wasInformedBy, wasGeneratedBy • startedAtTime, endedAtTime @timrdf http://bit.ly/prov-at-iswc-12

  9. Starting Points (Grid View) @timrdf http://bit.ly/prov-at-iswc-12

  10. Starting Points Example @timrdf http://bit.ly/prov-at-iswc-12

  11. Expanded Terms Includes subclassesand subproperties of Starting Point Terms, plus a few extras. @timrdf http://bit.ly/prov-at-iswc-12

  12. Extended Terms (1/5):prov:atLocationandprov:Location Location can be a geographic place (e.g. Paris, Locker-692) or a non-geographic place (e.g., directory, row, column, URL). @timrdf http://bit.ly/prov-at-iswc-12

  13. Extended Terms (2/5):prov:value(and prov:wasQuotedFrom) prov:value provides direct representation of an entity. It is similar to rdf:value. @timrdf http://bit.ly/prov-at-iswc-12

  14. Extended Terms (3/5):prov:specializationOf @timrdf http://bit.ly/prov-at-iswc-12

  15. Extended Terms (3/5):prov:specializationOf(andprov:wasRevisionOf)“provenance of dynamic resources” @timrdf http://bit.ly/prov-at-iswc-12

  16. Extended Terms (3/5):prov:specializationOf @timrdf http://bit.ly/prov-at-iswc-12

  17. Extended Terms (4/5):prov:alternateOf Two alternate entities present aspects of the same thing. These aspects may be the same or different, and the alternate entities may or may not overlap in time. @timrdf http://bit.ly/prov-at-iswc-12

  18. Extended Terms (5/5):prov:Bundleprovenance of provenance with a single Class! @timrdf http://bit.ly/prov-at-iswc-12

  19. Qualifying Terms • Starting point and Expanded relations are binary: • But we may want to provide more details about that use, or association… • When and wheredid the Activity use the Entity? • How did the Agent perform in the Activity? @timrdf http://bit.ly/prov-at-iswc-12

  20. QualifyingUsage @timrdf http://bit.ly/prov-at-iswc-12

  21. QualifyingAssociation @timrdf http://bit.ly/prov-at-iswc-12

  22. Qualifying Association:prov:hadRoleandprov:hadPlan (blank nodes for illustration ONLY!) (prov:had* naming convention*) @timrdf http://bit.ly/prov-at-iswc-12

  23. The Qualification Pattern Influence Derivation Quotation Revision PrimarySource Start End Usage Communication Generation Invalidation Association Attribution Delegation @timrdf http://bit.ly/prov-at-iswc-12
