One more precision related to my sentence:

If the semantics of relationalConceptSignature and
functionalConceptSignature are not hard-coded in the inference engines,
hence if role types cannot be used in the place of relation types
when making statements (as in: [Person:Mary]->(Father)->[Person:John]),
then the relation types must be generated (at least) when they are used
in statements (as in: [Person:Mary]->(father)->[Person:John]).
