Re: OWL Documents and new WG (was Re: New draft charter (was Re: Responses to "Draft of charter for NextWebOnt (Proposed) Working Group"))

My concern is that the group that has defined OWL 1.1 to date is not 
necessarily the same group that will be in the Working Group.  Thus 
the "decisions" have not been made yet and may need to be revisited - 
the charter could propose that the documents so far should be the 
basis of the new work, but they are not yet WG documents, and the 
features in this draft need to be approved by members of the WG who 
may not yet have joined or participated.  The decisions and features 
will need to be revisited, voted on, etc.  There might be new 
suggestions not yet in the documents (allDisjointList for example) 
and the new otganizations joining the WG might decide that some of 
those proposed are not appropriate for their needs, meaning new 
consensus would need to be reached.
   So I still worry about whether the scope and the time frame are 
appropriate, but I've made my points.  However, do remember that the 
documents to date are suggestions, not deliverables.
