I know I am a little late.

We are working with SKOS for a while now using it so long mainly for 
topic hierarchies. I just read the Reference and Primer once again and 
found some points to mention.

  * in the SKOS Primer (2008-08-29) Chap. 2.2.1 last sentence should 
tell "..., it is therefore recommended that no two concepts in the same 
KOS be given the same preferred lexical label --in any two given 
languages-- __in any given language__." (might be a typo)

Well, we cannot apply this recommendation, since we sometimes have 
different concepts with identical prefLabel, e.g. ex:football_(sport) 
and ex:football_(ball) both having skos:prefLabel "football", i.e. we 
don't want to disambiguate these concept by their prefLabel but by 
further characteristics as their definition or altLabel.
Same would apply, when you collect alternative definitions for a term 
resulting in different concepts, e.g. the medical term "sepsis" is 
defined in various variants from "inflammatory infection" over "blood 
poisoning" to "infection with organ dysfunction", and medics use it in 
such various manner.

So please leave it an informal recommendation.

  * in the SKOS RDF (2008-05-xx and 2008-08-29) #prefLabel the comment 
should tell therefore "No two concepts in the same concept scheme 
--may-- __should__ have the same value for skos:prefLabel in a given 
language." (according RFC 2119)

Kind regards
