SWI-Prolog owl logoClioPatria: the SWI-Prolog Semantic Web Server

SWI-Prolog offers an extensive library for loading, saving and querying Semantic Web documents called the semweb package. Internally, the query language is `Prolog', building on top of an efficient implementation of a predicate rdf/3 expressing the content of the triple store.

ClioPatria provides a ready-ro-run web-server on top of this infrastructure. The web-server contains a SPARQL endpoint, user management and web-based tools to help the developer analysing the loaded RDF.
