Well, if you want your RDF to interoperate, it needs to have a
consistent schema or a mapping between your RDF schema and the other

Using "explicate" where "explain" would do is not very "explicative".
In any case, I don't exactly understand the point.  Are you saying that
it is impossible to come up with a schema until all knowledge has been
