[protege-owl] problem loading galen.owl with protege 3 and protege 4

Thanks for checking this out. 

1. "very strange RDF"

 I am trying to use open-Galen in a project.  I believe it is Alan Rector 
(group) or Ian Horrocks at Manchester did the owl version of the Galen 
ontology, the original OWL file is at  I 
link I provided in my previous email is a copy at bioportal (same copy). 
Indeed, it looks strange in the class view in protege.  But I am 
interested in knowing what you meant by your above statement.   I am 
mostly interested in anatomy and pathology terms and relationships, and 
they can be found under "topcategory".

2. proptege 4 version;

4.0_alpha, downloaded this morning.  I used the option of "open OWL 
ontology".   When starting protege program, it has the following warning 
message about 'could not be found for logger'. 

3. not enough memory

After the "parsed: 220000 triples" line, there is no more displaying 
message.  the protege java process went on for about 1-2 minutes, then the 
system went to idle mode. 

I tried to change the memory size to 1G by changing the number in run.bat. 
 But it didn't do the trick for me. 

4. Loading in protege 3. 

yes, after increasing the heap size, I was able to load galen.owl file in 
protege 3. 

Do I need to change other settings in protege 4 in order to load this

One more thing.  This seems to be *very* strangely formatted RDF - do 
you know how it was created?
