Re: Hosted Triple Store Oracle RDF DM - and access to BioRDF examples in general

Many thanks, Sean.

I understand the need for a resolver, but I'd thought I'd remembered  
last Spring actually using this LSID plugin to look at the fruits of  
all that wonderful work Eric had done on RDFizing UniProt, but I  
guess that's just a memory phantom.  ;-)

By the way, I'm still not able to simply paste these lsid's into my  
Firefox URL line.  I just noticed in the LSID plugin Preferences I'm  
set to "Use Biopathways for DNS lookup".  Do I need to add Authority  
Mappings in order to reach the proper resolvers for those "working"  
LSIDs?

Thanks again for the remedial assistance.  I'm trying to move many  
tasks forward in parallel here and have to pick my troubleshooting  
battles carefully.  ;-)

Cheers,
Bill
