The "raw" translation simply translate each triple RDF in a ternary relation where each of the concept nodes of the relation will represent the RDF triple elements. It ensures soundness and completeness of homomorphism. However, this translation is not visual or in the spirit of Conceptual Graphs as such (the support is flat).

The raw translation of a triple:


raw mode use a predefined vocabulary:




This mode is interesting to demonstrate some properties but in practice, it cannot be used with big graphs because the application of all rules on the sum graphs of imports plus rdf(s) axioms quickly increases the graph size. To be used to find homomorphisms, this mode requires to add RDF and RDFS axioms as facts and to apply several RDF and RDFS rules. This facts and rules can be automatically created during importation. Check corresponding boxes on the wizard option panel:
