OPEN, no progress

OPEN, discussion continues, may require vote.

>  Likely consensus to POSTPONE this issue, but waiting to hear from 
>Ziv Hellman who raised it.  Email has been sent, if not replied to 
>by time we need it, we'll postpone the issue

RESOLVED: to POSTPONE (see minutes of today's telecon)

>Issue 5.8 - datatypes
>  I believe we have consensus to use the RDF solution.  We need to 
>call this question.  If we do accept this, we need to decide if 
>cardinality constraints will be expressed as datatypes or as numerals

OPEN - RDF is still not totally done w/datatypes - we cannot do much 
until we know what is happening there.

Peter P-S has sent a proposal to Close
  http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0329.html

>** Issue 5.13 - internet media type for OWL
>  Dan C has provided background document and there has been 
>discussion.  Currently it appears that application/rdf+xml is 
>sufficient, and that creating an application/owl media type would

We expect to request a new MIME type - Jonathan B. actioned to write 
this up.  Still unresolved if we will leave this open or close, but 
either way we will request feedback from public comments.

No change in status

No change in status

A proposal to add a mechanism that may help has been suggested.  Pat 
Hayes will write this up.  (see telecon log for today)

The names OWL LITE, OWL DL and OWL FULL have been resolved to be the 
names of our three langauge subsets.  Proposal not to include Classes 
as Instances in LITE is likely, but not yet approved - see Guus' 
message
  http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0310.html


>[Issue 5.21 - drop disjointUnion
>  This was closed last week, issues list needs to be updated to reflect this]


As yet unnamed issue - HASVALUE
Discussion as to whether hasValue should be included in OWL LITE. 
Discussed, but no resolution.  Discussion continues.
