Re: [OWLAPI-developer] question about example13

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi Claire,

You will need to get the source for these classes from the OWL API  
SVN.  However, I believe that sourceforge are performing maintenance  
on the SVN system so it you might not be able to access SVN until some  
time tomorrow.

Cheers,

Matthew
