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?
