Hi Helen,

Regarding Protege 4.

> I downloaded protege 4 and trying to open a local copy of galen.owl  
> [1].  The owl file is about 21M..  After loading 220,000 triples  
> (message on console), the system hung forever (I have to kill the  
> process after more than 30 minutes waiting).
> This is the same problem with protege 3.2.
> Can anyone share his/her experience in loading large ontology in  
> protege?  Is there a place where I can specify a larger memory  
> space for loading large ontology?

This ontology loads in a few seconds in Protege 4 for me. Some  
questions for you

What build of Protege 4 are you using?

How are you stating Protege 4?

Are you loading the ontology directly from the web?
