Re: metadata and ontologies

I would add that metadata can be represented using ontologies; and because
ontologies implements many desirable things in this context (restricted
vocabulary; text annotation; concept relationships; query language), they
are really useful.

Also, there are a lot of openly available metadata ontologies, such as the
Dublin Core.
