           The details of a provenance query service is an implementation choice, but for interoperability between different providers and users we recommend use of SPARQL [[RDF-SPARQL-PROTOCOL]] [[RDF-SPARQL-QUERY]].  The query service URI would then be the URI of a SPARQL endpoint  (or, to use the SPARQL specification language, a <a href="http://www.w3.org/TR/rdf-sparql-protocol/#conformant-sparql-protocol-service">SPARQL protocol service</a>).  The following subsections provide examples for what are considered to be some plausible common scenarios for using SPARQL, and are not intended to cover all possibilities.
