** Next Telecon
DECISION: Meet again same time, next week.
** Review of Completed Actions
All actions were considered completed.
** Progress on Primer Subgroup
EricM explained he spent some time putting together an outline,
pointing to core documents. He hopes to have people to meet
together on a telecon. DanC thought it'd be fine if it was
discussed on the normal RDF Core time. The time Eric proposed
was Wednesday at 10AM, which did not work for at least one of
the primer subgroup members (Aaron).
ACTION 2001-09-21#1: Eric Miller / Try to publish a TOC of primer stuff
ACTION 2001-09-21#1: Eric Miller / Organize telecon if needed,
and all interested parties can participate, if not, ask for
telecon time
** Issue: rdfs-no-cycles-in-subClassOf
Sergey decided that he was OK with dropping this restriction.
DECISION: To resolve issue rdfs-no-cycles-in-subClassOf by
deleting the restriction prohibiting cycles of subClassOf
properties. The meaning of a cycle of subClassOf properties
being an assertion that the classes involved have the same
members. A more formal specification of the meaning will be
given in the model theory.
Pat agreed to bring this decision back to the DAML Joint
Committee. We decided to put off approval of the test case until
next week when we had a better handle on how to structure the
test case directories. We decided next week we should look at
removing the restriction on subPropertyOf when Frank puts
together a similar proposal together.
ACTION 2001-09-21#3: Dan Connolly / Place
rdfs-no-cycles-in-subClassOf in proper place in directory
structure once that place is decided.
ACTION 2001-09-21#4: Pat Hayes / Take the subClassOf decision
back to DAML Joint Committee.
ACTION 2001-09-21#5: Frank Manola / Present similar proposed
resolution and test case for subPropertyOf cycles
** Model Theory Working Draft
We discussed that this doesn't change the current set of specs
any more than decisions the WG has already made, but merely
formalizes the text of the specs. We also agreed that this does
not mean we've formally agreed on everything in the draft,
merely that we feel it is ready to stay on the Web forever, and
that we're obliged to accept comments on that.
DECISION: Publish the Model theory Working Draft (with possible
minor cosmetic changes)
ACTION 2001-09-21#6: Dan Connolly / Act as staff contact for
publication of Model Theory Working Draft
** RDF Schema Status
While DanBri was absent, we noted that he reported by email that
he planned to have the WD next Wednesday for review. It might be
too late for us to review it by Friday, but it will go on the
agenda if it arrives.
** Propose test case
wg/2001Sep/0109.html
Jeremy explained that this was an XML error to catch those that
didn't use established MXL infrastructure. A number of people
looked at the test case and said it was fine.
ACTION 2001-09-21#7: Jeremy Carroll / Add a comment to explain
the error in
wg/2001Sep/att-0109/01-error001.rdf
DECISION: Approve
wg/2001Sep/att-0109/01-error001.rdf with above caveat
ACTION 2001-09-21#8: Art Barstow / Update
url/test001.rdf to include an explanation of the test case
(especially for those whose browsers convert & to & for
them).
DECISION: Approve
tests/rdfcore/amp-in-url/test001.rdf with above caveat
** Test cases that don't fit the RDF/XML -> N-Triples paradigm
Jos volunteered to write up a proposal of entailment tests, he
felt that it was a simple problem. Jan Grant suggested we use an
RDF manifest (manifest.rdf) of the tests to explain things to
automated tools.
ACTION 2001-09-21#9: Jos de Roo / Write up something to describe
these entailment tests (with help from Pat)
ACTION 2001-09-21#10: Jan Grant / Write up proposal for an RDF
test case manifest
ACTION 2001-09-21#11: Art Barstow / Collect the above materials
for inclusion the RDF Test Cases WD
** parseType QNames
Bill explained he was writing up another version of his
proposal, which should be on the list Monday. We should have a
yes/no vote on Friday. He explained the proposal only affected
future parseType's. There was some discussion about
incompatibility with some daml:collection parsers, but we seemed
to agree this was a minor point. (Note to those who have
daml:collection parsers, please make your parsers understand
this as a QName, not a fixed literal.)
ACTION 2001-09-21#11: Bill DeHora / Take proposal to the list
next week on parseType QNames
** Other discussions
ACTION 2001-09-21#12: Bill DeHora / Annoy Pat Hayes until
there's a Model Theory section in the primer

the decision, that is)
14:23:31
change it's name...
