Quite.  Some systems using ontologies (for example, the GALEN project at
University of Manchester*) make this distinction explicit.  In such systems,
one component reasons about the ontology and a different component
translates queries and results between the internal representation and one
or many systems of signs**.  This allows eg. multilingual querying and
results.  I'd argue that a system is incomplete if it does not provide a
many-to-one mapping between signs and objects within the ontology, but
that's a contentious view :-).

To me, a language for exchanging ontologies is just another system of signs.

*I've no doubt there are better examples, but I used to work on GALEN so
that's the one I know.

** I'm a programmer who's interested in using ontologies in practical
systems.  I have comparatively little logical or philosophical background;
is this the correct term?  If not, what is?
