Advice from W3 publications teams was to ont point to this from WDs

Item 8: Congratulations on a swathe of new WDs:
Champagne and strawberries all round.


Item 9: Outstanding issues: 9 left:
	rdfms-duplicate-member-props moved to AOB


Item 10: Issue rdf-charmod-resources

Jeremy: there's a new datapoint on this: the XML namespace group appears
to be using US-ASCII. We should clarify this, and proceed in the light
of that clarificaion.

ACTION 2002-05-03#1 (bwm) to review charter over this issue.

ACTION 2002-05-03#2 (jjc) to ask xml-namespace editors directly how
	xmlns="andre'" and xmlns="andr%xx" are related

AOB: rdfms-duplicate-member-props


Item 11: Issue rdfs-isDefinedBy-semantics

	http://www.w3.org/2000/03/rdf-tracking/#rdfs-isDefinedBy-semantics
	http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Apr/0478.html

Aaron's proposed resolution:

 - isDefinedBy is a Property
 - it has no further semantics in the RDF Model Theory

 - further subclasses of it may be created by others
 - it is out of scope for RDF Core to create these subclasses

No dissent.
ACCEPTED: tihs proposal was accepted.

ACTION 2002-05-03#3 (em) to ensure the primer covers the techniques
	of using isDefinedBy to point to schemas

ACTION 2002-05-03#4 (em) to liase with danbri to ensure primer and
	schema stay in sync over the isDefinedBy issue


Item 12: Issue rdfs-clarify-subClass-and-instance

Proposal: the WG resolves that -
 - subClassOf and rdf:type are defined in the RDF Model Theory
 - the RDF Schema spec and RDF Primer provide adequate descriptions of
	these properties

No dissent.
ACCEPTED.

ACTION 2002-05-03#5 (bwm) to close the issue, respond to the issue
	raiser with explanatory text (taken from the primer)


Item 13: Syntax Doc: serializing b-nodes
Postponed in the absence of the document editor.


Item 14:  Issue: rdf-namespace-change
	http://www.w3.org/2000/03/rdf-tracking/#rdf-namespace-change

It was felt that the WG would be seen as setting a precedent with this
decision. We should effectively communicate how hard we've deliberated
over this issue, and how we've struggled to keep from feature-keep and
deprecation in order to justify keeping the namespaces.

ACTION 2002-05-03#6 (bwm) to take the lead on the closure of rdf-namespace-change


Item 15: defining literal equality
Postponed in the absence of Pat Hayes.


Item 16: daml:collection

DanC's thread:
	http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Apr/0334.html

Some discussion at length on this. DanC, Jos both indicated that
first/rest-style processing was much simpler in their LP systems.
DanC indicated that WebOnt didn't like the "longhand" format.

ACTION 2002-05-03#7 (danc) summarise to the list the options for
	collections, with the objections that've been raised (or
	likelihood that "they'll fly")


AOB#1: http://www.w3.org/2000/03/rdf-tracking/#rdfms-duplicate-member-props

The question posed was: should an RDF parser reject the following as
illegal?

	<rdf:Bag rdf:about="http://example.org/foo">
		<rdf:_1 rdf:resource="http://example.org/a" />
		<rdf:_1 rdf:resource="http://example.org/b" />
	</rdf:Bag>

It was decided (no dissent) -
RESOLUTION: the WG resolves that this is syntactically legal RDF

ACTION 2002-05-03#10 (jang) add a test case to the suite reflecting this
	decision (rdfms-duplicate-member-props)


AOB#2: isDefinedBy - futhter discussion

The difference between seeAlso and isDefinedBy was discussed.
FrankM: we're not looking at reopening this, we're soliciting advice as
to what to say in the primer.


AOB#3: test cases seeking approval

JanG: heads up, there are more taht need approval.
ACTION 2002-05-03#8 (jang) push omre of the pending test cases through
	formal approval


AOB#4: schedule to going to last call.

DanC: I'm keen that "last call" shouldn't be "first call". We need to
keep pushing the community to read the WDs.

ACTION 2002-05-03#9 (em) dash off a quick 5-minute email with list of
	potential groups to colicit feedback from in Hawaii


The meeting closed.
