2. OPMV
• The goal
• The raBonale
• Overview of the vocabulary
• Overview of exisBng type modules
• Tools and examples
• Future development

3. Our Goal
• Enable “responsible” data publicaBon, in order
to trace the responsible agents and to
reproduce results
• Enable to describe provenance of any types of
data
• Easy to use and extend
– By people who publish Linked Data
– By developers of Linked Data publishing tools

4. ARTIFACT
Immutable piece of state, which may have a physical
embodiment in a physical object, or a digital
representaAon in a computer system.

5. The RaBonale
• Grounded upon exisBng SW technologies
– Do not explicitly define a graph, OPMGraph
– Named Graphs
• Reuse exisBng vocabularies
• Lightweight
– 3 classes and 12 properBes
– Reuse 3 classes from the W3C Time Ontology

6. Overview of the Vocabulary
• Defined as a vocabulary expressed using OWL
• Implement the core concepts of the Open
Provenance Model
• No specific granularity prescribed
• ParBBoned into:
– The Core Module
– Other typed modules: common, xml, gate, sparql

7. OWL Ontology for OPM

opm:account pc1:black ;
opm:label "Reslice 1" .
pc1:an1_p5 a opm:Annotation .
pc1:pr_18 a opm:Property ;
opm:uri "http://openprovenance.org/primitives#primitive" ;
opm:value "http://openprovenance.org/primitives#reslice" .
pc1:an1_p5 opm:property pc1:pr_18 .
pc1:p5 opm:annotation pc1:an1_p5 .
pc1:u_103 a opm:Used ;
opm:effect pc1:p1 ;
opm:role pc1:r_102 ;
opm:cause pc1:a3 ;
opm:account pc1:black .

opm:hasAccount pc1:black ;
opm:hasProcess pc1:p5 , ...;
opm:hasArtifact pc1:a25p, ...;
opm:hasDependency pc1:u_103, ...

10. Example: OPMV
pc1:p5 rdf:type opmv:Process ;
rdfs:label "Reslice 1" .
pc1:a3 rdf:type opmv:ArBfact
opmv:wasGeneratedBy [
rdf:type opmv:Process;
opmv:used pc1:p1
]
.
pc1:p1 rdf:type opmv:ArBfact .

11. Example: OPMV + Named Graphs
pc1:gr_273 {
pc1:p5 rdf:type opmv:Process ;
rdfs:label "Reslice 1" .
pc1:a3 rdf:type opmv:ArBfact
opmv:wasGeneratedBy [
rdf:type opmv:Process;
opmv:used pc1:p1
]
.
pc1:p1 rdf:type opmv:ArBfact .
}
pcl:gr_273 rdf:type <hgp://www.w3.org/2004/03/trix/rdfg‐1/Graph> .

12. Comparison with OPM OWL
• A more intuiBve OWL ontology and RDF
representaBon
• Take full advantage of SW technologies
• Lack of explicit semanBcs for graph
membership
• Not too much for reasoning
• (Probably) a less complete implementaBon of
the OPM SpecificaBon

17. Example

18. Publishing OPMV Provenance
• ProvenanceJS (Hands‐on session)

19. Future Development
• More typed modules
• A guide on how to publish provenance
– Where and how much
– What is the minimum provenance
– How to represent the informaBon
