Issue 5.21 - drop disjointUnion: Resolved Oct 24 telecon
Issue 4.4 - extra-logical feature set: Postponed at Oct 31 telecon
Issue 5.7 Range restrictions ....: Postponed at Oct 31 telecon
New issue: hasValue in OWL Lite?
   http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0196.html
New issue: if or iff for property properties
http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0202.html


** Issue 4.3 Structured datatypes

ACTION: Jonathan Borden to write up a proposal for issue 4.3
DONE
http://lists.w3.org/Archives/Public/www-webont-wg/2002Nov/0037.html


** Issue 4.6 - equivalentTo

Still open and to be discussed - depends in part on formalism issues
(note that we will still need to decide the issue of whether we
offer equivalentTo as well as the sameXXXAs constructions - as well
as whether equivalentTO is limited to same "type")

Proposal to close by Peter P-S
     http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0327.html

Some object, prefer a separate "sameAs" construct, e.g.:
http://lists.w3.org/Archives/Public/www-webont-wg/2002Nov/0027.html


** Issue 5.5 - List Syntax or Semantics

ACTION: Chairs Guus and Jim: discuss 5.5 List syntax or
semantics in RDF CORE, Semantic Web Coordination

Now that RDF Core has a list construct, the question of what it
looks like is resolved, but the issue of whether the semantics are
in RDF or OWL remains.  I assume this will be dealt with in the
formalism document

See Jeremy's message plus follow-up:
http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0203.html


** Issue 5.6 - imports

This has been discussed, and we are working towards resolution.  I
believe we have consensus on the desired behavior, but are
struggling with how to write this up.

OPEN, discussion continues, may require vote.


** 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

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


** Issue 5.9 - malformed D+O restrictions

This is essentially subsumed by the semantic document - we need to
take an action to either withdraw this issue or to declare it closed
- PFPS is issue owner.

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
take extra work.  We need a proposal to close this issue.

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.


** 5.14 - Ontology versioning

Jeff proposed a solution, it engendered much discussion, but we've
not yet reached a concensus.  I believe there might be some
consensus to go with his Backward-compatible and extends, while
there is resistance to Deprecates.  Jeff proposed these as
extra-logical restrictions (i.e. operational rather than formal
semantics) minutes seem to reflect soem resistance on part of some
of WG to this. We need a proposal to move this issue forward.

No change in status


** Issue 5.17 - XML presentation syntax

Peter Patel-Schneider working on this as a document.  We should
CLOSE this issue with resolution to produce the document.

Review by Hori:
http://lists.w3.org/Archives/Public/www-webont-wg/2002Nov/0034.html


** Issue 5.18 - Unique names assumption

ACTION: Dan Connolly to write up the 'all different' proposal for
issue 5.18

Message of De Roo about test for 5.18:
http://lists.w3.org/Archives/Public/www-webont-wg/2002Nov/0021.html

We need a proposal to close this issue.  One possibility is to
accept that the differentThan construct is good enough.  Another is
POSTPONE this issue and to demote the requirement to an
objective. Alternatively, someone could propose a mechanism that the
formal document could endorse - needs action.
Deb McGuinness is issue owner.


** Issue 5.19 - Classes as Instances

ACTION: Guus, Frank: to move the issue forward, will write up 1-d
and 2-d views to make clearer to users.
DONE:
http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0310.html

We have resolved these are included in large owl.  Some discussion
of whether they are allowed in Owl Lite.  Majority reflected
willingness to leave out of OWL Lite, but some dissent.  Someone
needs to suggest a specific action, or we should Close this issue
with resolution that these are allowed in Large OWL (implying they
are not part of Lite).

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 "hasValuue in OWL Lite?"
http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0196.html

http://lists.w3.org/Archives/Public/www-webont-wg/2002Oct/0202.html

Language (OWL) and then reference version (1.1.0).
