Webont meeting at W3C Plenary: March 4, 2003
4:30 PM to 7:00 PM
Scribe: M. K. Smith

1. Named datavalue lists discussion.

See the ugly test case email in January from Jeremy.

<owl:DatatypeProperty rdf:ID="foo">
   <owl:DataRange [rdf:ID="rrr"]>
    <owl:oneOf> ... </owl:oneOf>
   </owl:DataRange >

<owl:DatatypeProperty rdf:ID="bar">
  <rdfs:range [rdf:resource="rrr"]/>

Originally proposed as temporary fix, thus not named. We expect
XML:Schema to ultimately provide a mechanism to support this

So current consensus is NOT to provide a naming mechanism for these in
DL.  If you name it, you are in Full.  But see action.

ACTION: Peter/Ian.  Is it a problem to provide such a name?
ACTION: Guus.       Add words to reference if change.

2. RDF compatibility

Container vocabulary.  S&AS forbids.

rdf:Bag cannot be owl:Class
User could define usr:Bag with same (similar?) properties.

Positive version: Include explicitly.
Neutral version:  Don't dissallow RDF container and reification vocabulary.

ACTION: Peter to check modifying rdf exclusion to a list of excluded

3. rdf:XMLLiteral


1. allow
2. disallow
3. allow only if request to RDF Core is granted.

We believe that accepting XMLLiteral as it is doesn't work.

If our request is granted, then can we make this work.

Peter argues that rdf:XMLLiteral and owl:Literal provide essentially
the same capabilities.

Much discussion revolving around treating XMLLiteral equivalence as
string eq, benefits for general XML related reasoning are obvious.

No agreement reached.

4. User defined XML schema datatypes not in scope given their
lack of names we can reference.

5. ACTION: Peter and Jeremy to discuss unnamed individuals.

6. PROPOSAL: Admit unsupported data types such that they depend on
identitity of URI literals, but no more.

7. ACTION: Peter to allow optional objectProperty typing for special
categories of object properties.

8. ACTION: Peter, Jeremy: Peter to add triple table of Jeremy's after
Jeremy updates.
