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
guy's.  This is exactly the same situation with XML Schema.

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
captured?
