Re: Access to DUL.owl ontology

Hi Kerry,

My mail was merely a reaction to your claim that there is no broken link 
to DUL in the old SSN. If we are allowed to revisit the old SSN and to 
fix the link, this would be absolutely great and we should try to do 
this as it leads to problems on a regular basis. If this would need 
somebody to volunteer to change that link in the final report and 
ontology, I would be more then happy to do so if it would help all of 
us. Btw, am I correct assuming that 
http://www.w3.org/2005/Incubator/ssn/XGR-ssn/ is the proper link to the 
final report of the incubator group?

Best,
Krzysztof
