Polyflow: a Polystore-compliant Mechanism to Provide Interoperability to Heterogeneous Provenance Graphs

Many scientific experiments are modeled as workflows. Workflows usually output massive amounts of data. To guarantee the reproducibility workflows, they orchestrated by Workflow Management Systems (WfMS), that capture provenance Provenance represents lineage a data fragment throughout its transformations activities in workflow. traces represented graphs. These graphs allows scientists to analyze and evaluate results produced However, each WfMS has proprietary format for do it different granularity levels. Therefore, more complex scenarios which scientist needs interpret generated multiple WfMSs challenge arises. first understand research landscape, we conduct Systematic Literature Mapping, assessing existing solutions under several lenses. With clearer understanding state art, propose tool called Polyflow, is based on concept Polystore systems, integrating databases heterogeneous origin adopting global ProvONE schema. Polyflow query an integrated way. was evaluated experts using collected from real generate phylogenetic trees through The experiment suggest viable solution interoperating WfMSs, both usability performance standpoint.
