Description

Data provenance is the history of derivation of a data artifact from its original sources. As the real-life provenance records can likely cover thousands of data items and derivation steps, one of the pressing challenges becomes development of formal frameworks for their automated veri fication. In this paper, we consider data expressed in standard Semantic Web ontology languages, such as OWL, and de fine a novel verifi cation formalism called provenance speci fication logic, building on dynamic logic. We validate our proposal by modeling the test queries presented in The First Provenance Challenge, and conclude that the logic core of such queries can be successfully captured in our formalism.
