Semantically rich metadata is foreseen to be pervasive in tomorrow’s cyber world. People are more willing to store metadata in the hope that such extra information will enable a wide range of novel business intelligent applications. Provenance is metadata which describes the derivation history of data. It is considered to have great potential for helping the reasoning, analyzing, validat-ing, monitoring, integrating and reusing of data. In this paper, we introduce Butterfly, a provenance management system, which offers the modeling, storage, and query of provenance.
