Re: LSIDs and ontology segmentation

[Benjamin H Szekely]

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

urn:lsid:ncbi.nlm.nih.gov.lsid.biopathways.org:ontologies:MIM

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.
