Yes, I always point them to the new version, but that is not the point 
here. The point is that our official deliverable of the old W3C XG SSN 
group points to an URI that does not exist anymore and this is why 
loading in the original SSN ontology that we published leads to an error 
message and this happens very frequently namely whenever somebody reads 
our 'Semantic Sensor Network XG Final Report' 
(https://www.w3.org/2005/Incubator/ssn/XGR-ssn-20110628/) as this points 
them to the ontology at https://www.w3.org/2005/Incubator/ssn/ssnx/ssn 
which imports the DUL URI that does not exist any longer and this has 
been a problem for a long time and this is what I said in the the call 
today.

Best,
Krzysztof
