As Stella pointed out it's not that easy to tell what is a thesaurus,
taxonomy, classification scheme etc. I think it's more relevant what
specific features of a controlled vocabulary you want. I am working on a
general typology of knowledge organization systems based on properties
and features rather instead of types [1] but this is probably still too
vague and informal. With SKOS we should define a set of semantic,
formally defined features. Alistair started with the obvious condition
that should apply for all concept schemes [2].

An additional features of a concept schemes could be that hierarchic
relations do form a tree - then it's a kind of taxonomy or
classification scheme and you can use other presentations than in a
multi-hierarchical concept scheme.

What kind of open source components do you plan?

Greetings,
Jakob
