Hi Antoine,

I am not sure I understand. Are you saying that it is a problem that a 
separate URI would be assigned to the same term in the terms-as-class 
solution, while this would not happen in the current solution because 
they are just labels?

Then this is just a problem that either (a) there is an 'error' in the 
thesaurus anyway because the term is repeated (b) the conversion just is 
a little bit harder because we'd have to detect if the term already 
exists, or is really different.

I don't see this as a reason not to go for the term-as-classes solution, 
as any existing RDF Schema can be used wrongly.

Yep, very right. But there are some other 'errors' or constraints that 
the SKOS schema itself does not prevent/enforce, e.g. 'No two concepts 
in the same concept scheme may have the same value for skos:prefLabel in 
a given language.' We could include just one more constraint or 
'warning' rule.

Lastly, like I said earlier, I think it is more important to flag the 
issue in the Change Proposal/Issue list than to try to solve it now. 
(Although I enjoy discussing it very much!)
