I appreciate your enthusiasm, but going beyond simple broader,  
narrower, and related would demand a full-blown re-analysis of the  
ontological entries.   Frankly, updating content, getting the old  
entries into rough correctness and legibility was already enough work.

Sounds like extended SKOS is so OWLish, that those wanting real  
ontological info would be happy to have the OWL version (which one  
could slowly mold into the right ontological form).   The bare-bones  
SKOS looks like a token list to me, and that's all I'm interested at  
first.

How about micro-OWLness as a start?  Again, if someone would tell me  
explicitly what OWL-ish entries you like......
