Experiencing PROV-Wf for Provenance Interoperability in SWfMSs

Analyzing disperse and heterogeneous provenance data usually requires using higher-level tools which scientists need to learn. In our view, scientists should be able to analyze provenance in the SWfMS of their choice. In this paper, we propose Gefyra, an architecture based on the PROV-Wf model, which provides a way to capture heterogeneous provenance data from different SWfMSs into a single format. Gefyra exports and imports provenance data to/from different SWfMSs, allowing scientists to use the system of their choice.
