Hi All,
    What Mark points out, quoted below, is absolutely correct.  In the 
NCBI prototype ontologies, every OWL Class and Property has its own LSID 
and resolves to the small amount of RDF that encapsulates it.  As an 
example, resolve the LSID for the OMIM ontology


in Firefox Launchpad via: 
lsidres:urn:lsid:ncbi.nlm.nih.gov.lsid.biopathways.org:ontologies:MIM. One 
can navigate the entire ontology by surfing the LSID metadata associated 
with each ontology node.
