TripleProv

TripleProv is a new system extending a native RDF store to efficiently handle provenance inside data stores.

Storing, Tracking, and Querying Provenance in Linked Data

In our work we presented a system named TripleProv 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 querywere 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. For example, if you are interested with articles about “Obama”, but you want the answer to come only from sources attributed to “US News”.
