[Pellet-users] ANN: Owlgres 0.1 (Alpha Release)

[James Howison]

This looks interesting.  Assuming your ontology fits its capabilities,  
the advantage of this over full Pellet, and for example the Jena  
reasoners, would be that because it is using the database there is no  
need to load the whole ontology into memory (because it is using  
postgres?)

Thanks,
James
