Re: ssn: action-155

Hi Kerry,

Sure. One of the reasons to include DUL in the original SSN was the need 
for a stronger semantic anchoring of the classes and relationships 
defined in SSN. One problem we faced was that terms such as Sensor, 
System, Observation, were under-specific to a degree where a major part 
of the intended interpretation of these classes was encoded in terms of 
their labels. DUL gave us additional axioms to further refine what was 
meant by 'Sensor', 'Observation' and so forth. Removing DUL, will leave 
us with the same problem as we had before, and, thus, I proposed to make 
use of the power of OWL2 to add a stronger axiomatic foundation to SSN
