TripleProv - RDF Provenance

TripleProv is an in-memory RDF database capable to store, trace, and query provenance information in processing RDF queries. TripleProv returns an understandable description of the way the results of an RDF query were derived; specifically it gives a detailed explanation which pieces of data and how were combined to produce the answer of a query. Moreover, with TripleProv you can tailor query execution with provenance information. You can input a provenance specification of the data you want to use to derive the answer.
