PROPOSAL TO CLOSE ISSUES 3.4 AND 4.1 (UniqueProperty and UnambiguousProperty) Welty

Proposal: OWL FunctionalProperty OWL InverseFunctionalProperty

Many: Welty’s proposal is good. Jim: add 1-1 property? Peter: later Jim: straw poll: any objections? Mike: but can be 0-0 or 1-1. Resolution: unanimous. Adopted Chris Welty’s proposal. So, will go with what we have, not yet include 1-1. STATUS: RESOLVED.

See Chris Welty’s proposals: http://lists.w3.org/Archives/Public/www-webont-wg/2002Jul/0170.html http://lists.w3.org/Archives/Public/www-webont-wg/2002Jul/0169.html

See Mike Smith’s Issues document: http://www.w3.org/2001/sw/WebOnt/webont-issues.html#I3.4-UnambiguousProperty

http://www.w3.org/2001/sw/WebOnt/webont-issues.html#I4.1-UniqueProp-BadName

ACTION: Mike Smith will close this out. Jim: someone has to do the TEST case. ACTION: Jeremy to do TEST case. ACTION: Deb, Mike, Peter to reflect this change in their documents, prior to release.

PROPOSAL TO CLOSE ISSUE 2.4 (oneOf)

Ian was invited to discuss this, but nothing much showed up yet. Deb: he is still working on this. Dan: cardinality and oneOf interaction test case? Has anyone else seen this? Jeremy: has seen some, look hairy. Jim: no one has suggested we don’t have oneOf. Should we remove? It’s currently heavily used.

Straw Poll: No objections. No abstentions. PROPOSAL PASSES. Issue is CLOSED. STATUS: RESOLVED.

ACTION: Jim to write up a test case.

Should we have oneOf in OWL-Lite? Jeremy: Feature vs. Issue driven test cases? Dan: just use of oneOf. Entailment test. Jeremy: test cases to be in a hierarchy structure? Prefer to see feature-based test cases higher view. Jim: today we are closing everything that could affect the 3 docs. Next week, talk about next documents. August 15th: semantic issues. Probable cancel of Aug. 8th.

PROPOSAL TO CLOSE ISSUE 4.6 (equivalentTo)

Jim: email looks like other opinions. Is there a consensus? Peter: 2 issues: 1) same individual as (2 names denote same) implies same class as and same property as (follows RDF view). Same property does not denote same individual. Dan: doesn’t affect the documents. ACTION: Peter will send out longer note and people to reply. Peter: by next week. ACTION: Jim will REMOVE proposal to close issue.

Class as instance discussion. Peter: model theory has a weak view of class as instance. Property defined-by attached to class. Average price property? First is not a property of the extension. Jim: can we close 4.6 because it’s subsumed by this issue (classes as instances). No, so just leave separate.

OPENING OF ISSUE 5.20 (SHOULD OWL PROVIDE SYNONYMS FOR RDF AND RDFS OBJECTS?)

Jim: opening this issue, discuss, get feedback, send to email. Peter: nothing substantive; legalistic: D+O pulls into D+O namespace, but RDF will not pull into the RDF/S namespace (but RDF/S does not have capability).

OWL:PROPERTY: same denotation? RDFS:PROPERTY? Not to have the former in the OWL namespace when they’re both equivalent. Issue: will RDF tool understand what OWL:PROPERTY is?

Jim: at the last F2F, no resolution. Namespace of the identifier should be the definitive identifier. If we have a different model theory (different from RDF), then have a different namespace (i.e., OWL namespace). Do we need a separate model theory for OWL? Yes, for things not in the other language. If we extend RDF/s, need to have a model theory for this. Much discussion.

AOB next telecon: Aug. 1 next scribe: Mike Smith

Aug. 8 meeting: cancelled.
