Hi Alistair,

Very nice summary of these problems!

Some small comments, if you wish to complete your doc (not crucial in my 
opinion):
- the need for annotating owl:Class is not obvious for me (typical 
thesauri in Cultural Heritage do not pretend to be ontologies). Perhaps 
you should link somewhere to the requirement (not mentioned in the list, 
because it's supposed to come with RDF nature of SKOS and OWL) that says 
that skos constructs shall be used in combination with OWL, especially 
because some applications require 'real' ontologies to be considered as 
SKOS concept schemes
- whatever be the solution wrt. the issues on linking and annotating 
labels [1,2] (that is, keeping prefLabel as a datatype property or 
changing it to a object propery linking two resources) the problem 
remains, since object properties cannot be applied to owl:Concept 
without breaking OWL-DL validity.

Cheers,

Antoine
