Dear Michael

Thank you for your comments [1,ISSUE-137]:

Property disjointness is not expressible in OWL Full. This should be  
somewhere in the document, I think. Property disjointness is,  
however, planned
to be expressible in OWL 2.


As you point out, there are some constraints in the SKOS data model  
that we are unable to express in OWL (some of these /may/ be  
addressed by OWL 2, but in the current SKOS specification we are  
avoiding reference to work in progress). In such cases, the  
constraints are expressed in prose in the document. Property  
disjointness is precisely one of these cases.

Statements to this effect are made in Section 1.7.1 of the LC draft.  
Do you feel these are sufficient, or do we need to further elaborate  
this point?

The Working Group propose to *postpone* this issue, indicating that  
this may be an area that future groups may wish to return to. Are you  
willing to live with this?
