Is there an NCBI taxonomy in OWL ?

Hi,

I was looking for an NCBI Taxnomoy in OWL, but I didn't find it (or  
better, could find fragment from other projects...)

What is strange though, is that on the obo foundry website  
(berkeleybop.org/ontologies) there are notes on the ncbi taxonomy  
representation in owl... but not the representation itself.

Does anybody have some hint about where I can fin an OWL version ? Or  
even an RDF version ? Even better would a sparql endpoint containing  
it...

best,
Andrea Splendiani
