Metadata is a non homogeneous collection of data about data without an overarching scheme of data organization structures.

 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.

Simply put:
Metadata is easy; ontologies are hard ;-)

Sorry.

But maybe because:
Metadata is something you can't much argue about the values of;
if it is an ontology you can argue, and probably will.

For example:
I can tell you what my mother's Maiden Name was; and I could tell you what her Birth Name was.
That's metadata.
But if you started to discuss whether they were the same (they weren't), you would have moved beyond the world of metadata.

No pointers, I'm afraid, but examples.
