ProvenanceQuery provide a set of methods for querying the provenance data. Provenance data can be queried using the traditional SQL queries, SPARQL format, and using the following format to combine both queries: USING (SQL/SPARQL query) EXECUTE (SQL/SPARQL query) or USING (SQL/SPARQL query) UNION (SQL/SPARQL query) The results of the query in the USING clause are used as variable values for executing different instances of the query in the clause EXECUTE or to join their results then the clause UNION is used.
