Hi Tom,

I agree that conversions are tricky, but isn't an important reason for 
designing SKOS to be able to convert existing thesauri to the Semantic 
Web? I'm not suggesting automated procedures, merely pointers to 
technology/tools/guidelines people might use to design a conversion for 
their specific case.

My suggestion for a "conversion" section is based on the idea that 
people that are interested in the (Quick) Guide, are interested because 
they (a) want to know if there are benefits of an RDF version of a 
thesaurus and (b) aren't experts so would like pointers on how to do 
conversion. So maybe I have a wrong idea of the intended audience, what 
is your view on this?
