2. Our Goal
● Integrate provenance metadata into the Web of
data to enable information quality assessment
● Vocabulary to describe provenance of Linked
Data on the Web
● Easy to use
● By people who provide Linked Data
● By developers of Linked Data publishing tools

3. Overview of the Vocabulary
● Defined as an OWL ontology
● Partitioned into:
● Core ontology
● Supplementary modules: types, integrity verification

5. Example
< > a prv:DataItem ;
foaf:primaryTopic <http://example.org/gene/0030840> .
prv:createdBy [
a prv:DataCreation ;
prv:performedAt "2010-03-01...00:00"^^xsd:dateTime ;
prv:performedBy <http://example.org/triplify> ;
prv:usedGuideline _:a ;
prv:usedData _:b ] .
<http://example.org/triplify> a prv:NonHumanActor ;
rdfs:comment "Instance of Triplify V0.5" ;
prv:operatedBy <http://olafhartig.de/foaf.rdf#olaf> .
The data item was created by a process, performed at a given time and
performed by a service ex:triplify that was operated by myfoaf:olaf.

6. Example cont.
_:a a prvTypes:TriplifyConfiguration , prv:CreationGuideline;
prv:createdBy [ a prv:DataCreation ;
prv:performedBy <http://olafhartig.de/foaf.rdf#olaf> ] .
_:b a prv:DataItem ;
prv:retrievedBy [
a prv:DataAccess ;
prv:performedAt "2010-03-01T12...00:00"^^xsd:dateTime ;
prv:performedBy <http://example.org/triplify> ;
prv:accessedService [
a prv:DataProvidingService , prvTypes:JDBCService ;
foaf:homepage <http://flybase.org/> ]
].
The source data item _:b –used to create the data item described before–
was retrieved by ex:triplify by accessing a public JDBC access point.

7. Design Principles
● Usability and understandability
● No specific granularity prescribed
● void:Dataset rdfs:subClassOf prv:DataItem
● rdf:Statement rdfs:subClassOf prv:DataItem
● Other vocabularies for more detailed
descriptions of certain aspects
● OPMV, PML, HTTP vocab, Changeset, etc.
● Schema-level links to related Vocabularies
● e.g. prv:Actor owl:equivalentClass foaf:Agent

8. Provenance-enabled Publication
● Metadata components
for widely used Linked
Data publishing tools
● Triplify
● Pubby
● D2R Server
● Automatic generation
of provenance metadata
● Simple configuration

9. Future Work
● Alignment with other provenance-related
vocabularies and models
● Additional modules for specific aspects that
are not covered by other vocabularies
● Integration in other publication tools
