Open Provenance Model Tutorial Session 7: Open Provenance Model Vocabulary

OPMV

• The goal• The rationale• Overview of the vocabulary• Overview of existing type modules• Tools and examples• Future development

Our Goal

• Enable “responsible” data publication, 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

ARTIFACT

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

The Rationale

• Grounded upon existing SW technologies– Do not explicitly define a graph, OPMGraph– Named Graphs

• Reuse existing vocabularies• Lightweight

– 3 classes and 12 properties– Reuse 3 classes from the W3C Time Ontology

Overview of the Vocabulary

• Defined as a vocabulary expressed using OWL• Implement the core concepts of the Open

Provenance Model• No specific granularity prescribed• Partitioned into:

– The Core Module– Other typed modules: common, xml, gate, sparql

Example: OPMV

pc1:p5 rdf:type opmv:Process ;rdfs:label "Reslice 1" .

pc1:a3 rdf:type opmv:Artifactopmv:wasGeneratedBy [

rdf:type opmv:Process;opmv:used pc1:p1

].

pc1:p1 rdf:type opmv:Artifact .

Example: OPMV + Named Graphs

pc1:gr_273 {pc1:p5 rdf:type opmv:Process ;

rdfs:label "Reslice 1" .

pc1:a3 rdf:type opmv:Artifactopmv:wasGeneratedBy [ rdf:type opmv:Process; opmv:used pc1:p1

].

pc1:p1 rdf:type opmv:Artifact .}

Comparison with OPM OWL

• A more intuitive OWL ontology and RDF representation

• Take full advantage of SW technologies• Lack of explicit semantics for graph

membership• Not too much for reasoning• (Probably) a less complete implementation of

the OPM Specification

Publishing OPMV Provenance

• ProvenanceJS (Hands-on session)

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 information
