RDF to Conceptual Graphs Translations Calculating Shatterproof Transponds

In this paper we will discuss two different translations bet ween RDF (Resource Description Format) and Conceptual Graphs (CGs). These translations will allow tools like Cogui and Cogitant to be able to import and export RDF(S) documents. The first translation is sound and complete from a reasoning view point but is not visual nor a representation in the spirit of C onceptual Graphs (CGs). The second translation has the advantage of being natural and fully ex- ploiting the CG features, but, on the other hand it does not apply to the whole RDF(S). We aim this paper as a preliminary report of ongoing work looking in detail at different pro and the cons of each approach.
