We have proposed a mapping between RDF(S) and Conceptual Graphs (CG), available in the proceedings of ICCS 2000 (Darmstadt, August 2000). We map RDFS resource class and property types onto CG support (resp to Concept and Relation types) and RDF statements on CG. We then exploit the projection operation to query the RDF/CG base. The projection takes advantage of the resource and property hierarchies in order to find specializations of given types. Surprisingly, we can use RDF itself as a query language because as RDF statements are translated into CG, an RDF query statement is translated into a CG query. We have developped a prototype, called Corese, with F. Southey's Notio CG platform and ICS Forth VRP RDF parser. A Web page is available at : http://www.inria.fr/acacia/soft/corese.html The Corese engine hence enables to query an RDF metadata base and to find appropriate documents annotated by these metadata.
