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

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

ARTIFACT 

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

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

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

Comparison with OPM OWL

•  Take full advantage of SW technologies
