Within the context of KOSs, I understood that skos:prefLabel should be used for the 'term' or 'word' that had traditionally been used as the concept identifier. That is the reason for the cardinality constraint.
Is there the same notion for a ConceptScheme?
I don't think so, and would be included to use dc:title since that is the element used most widely for a generic label.

OTOH the elaboration below appears to focus more on nesting and hierarchies, or perhaps governance? (i.e. subsets with different governance arrangements) in which case I don't see the merit in using skos:prefLabel as I think it was designed for an orthogonal concern.

Hi Alistair:

Yes, basically this is my question. Thinking primarily in an
application where a KOS can be represented with several Conceptscheme.
A response from Christophe I understand the need to use DC to describe
each Conceptscheme as a resource. I would also add SKOS labels for
querying and browsing the KOS.

For now, the solution I implemented in the KOS Management System, I am
developing is:

* Each Concept, Conceptscheme and Collection, must be labeled with at
least one prefLabel.

Bear in mind that a resource should only have one prefLabel per language tag [1], so the above is fine as long as you meant to have all the prefLabel's in different language tags.

* Optionally, the user can add Dublin Core Metadata.

To describe the taxonomies in Drupal 7, we use dc:title to label ConceptScheme resources and skos:prefLabel/rdfs:label to label Concept resources, but there seem to be no strict guideline on this.

So, I think it would be best to label a Conceptscheme with at least
one prefLabel, and optionally add DC.

What do you think?
