RE: [ontolog-forum] Wordnet Representations - XSD/RDF/OWL

Hi Mike,    (01)

Looks mighty interesting!     (02)

re. OWL - (I assume you mean OWL DL) I'm not entirely sure of the pros/cons 
overall, but I'd be tempted to define the schema/ontology using owl:Class 
rather than rdfs:Class and so on to start with, it should be easier to loosen 
later than tighten. It should be fun in the reasoners too ;-)    (03)

There's some related material (you've probably seen before, but just in case!) 
around the recent ESW RDF Thesaurus work:     (04)

http://esw.w3.org/topic/RdfThesaurus    (05)

Cheers,
Danny.    (06)
