The Resource Description Framework Gateway (RDF Gateway) is a distributed data semantic query service.

New query methods other than the traditional centralized model have been made possible by RDF. RDF Gateway employs a RDF logical inference layer (RDF + Inference, or RDFI) operating on RDF triples, on top of an RDF interpreter, which allows the semantics of structured data to be machine understandable via Resource Description Framework Query Language (RDFQL) queries.

RDF Query Service (RDFQS) processes RDFQL queries from applications. RDF Data Service (RDFDS) eposes underlying data via an RDFDS Connection Interface.

The RDF Gateway site also lists several links to other sites covering RDF + Inference information.
