State of the art SPARQL query engines for PROV-O?

Greetings,
 As part of this summer's DataONE internship, we are interested in cataloguing SPARQL query engines, with or without triple store back ends (e.g. ARQ / Jena does not require one), that the PROV community has been using to manage and process PROV-O documents.

Any insight from the PROV-O superusers in this group?

Thanks —Paolo
