it is difficult to comprehend an issue when one is party to just one  
side of the conversation. i suppose i could follow the archive, but  
that would be rather cumbersome. i proceed as you suggest.

thank you.

yes i have. my concern could be addressed by adding a normative  
appendix which specified an ontology profile for each of the three  
use cases that i described, below. i did read, that there are  
categories of terms - on one hand basic/extended/qualified and on the  
other subclasses of respective category, but there is
a, no indication that a compliant provenance information source may  
provide just a subset,
b, no coherent subset is describe for any of these use cases, and
c, it may be, that some cross section of those categories is  
appropriate to achieve coherence for these use cases, and, in  
particular, perhaps a different one for each case.

the working group may feel, that this is not within your mandate, but  
rather it is the responsibility of a sparql working group. to that, i  
can only reiterate my observation, that the two sparql/rdf  
implementations evident in the w3c list did not share a view of what  
those profiles should be, which certainly does not contribute to your  
group's interoperability goal.

best refards, from berlin,
