A set of modules allowing you to export prolog predicates as RDF just by declaring mappings, and access them through a SPARQL end-point.
A match file (such as examples/jamendo_match.pl) specifies how a prolog predicate can translate to RDF. Once written, launch run.pl, load your match file(s), load the Prolog modules defining the predicates you want to export, and run server,entailment(p2r)..
Once your mapping is finalized, and if you want your end point to be faster, you can cache all the potentially derived RDF triples in a local persistent triple store. To do so, just load your match file and corresponding prolog modules, and run init_db,rdf_compile.. Then, when you restart your server, you just have to run init_db., and nothing more.
You can also dump all RDF statements in a RDF/XML file, by running rdf_dump.
