I'm wondering if Nepomuk can support, maintain, and import thesauri - NOT a flat 'dictionary' thesaurus like Roget (implemented in, say, KThesaurus), but a structured metadata schema / taxonomy with, at least, hierarchical relationships (Broader - Narrower terms).

Ideally, I want to be able to tag documents using a thesaurus, eg, Function (Broad Term) - Activity (Narrow term) - Transaction (Narrowest Term) - (document / file name).

I also want to be able to maintain the thesaurus (add / remove terms), as well as import it.
