Last Week's Minutes
The minutes from October 30 were approved by those present.
We'll defer review of the November 6 minutes to next week.
All the required information has been collected. Even the
Lucent lawyers have responded. The pieces had passed the W3C
style checkers and pass the ones that are working today. Peter
re-submitted the package at 2pm EST today!
W3C Web Ontology Working Group
had its initial (mostly administrative) telecon yesterday,
with about 40 participants.
The next telecon will be
in about two weeks. The first face-to-face meeting is scheduled at Bell
Labs 14 and 15 January 2002.
No action from Benjamin and Ian yet. Benjamin is supposed to be
doing something. Harold says that
is progressing, and
moving from a DTD to an XML Schema base. There are
to be overcome, particularly with inheritance in XML
Schema. There are opportunities with respect to providing meaning
for XML Schema and DTDs.
Harold, Benjamin, and others will have a
Rule Markup Techniques.
Richard thinks that rules + DAML is a high priority and is
wondering why it is not progressing. What can be done to
jump-start this? Several problems came to mind, including lack of
concentrated effort and basic philosophy. Pat thinks that there
are easy ways to progress, maybe not the best ways, however.
Harold suggested a layered approach, which Ian says has problems.
The general consensus is that rules will take quite a while,
particularly as there is little time pressure. One possibility,
suggested by Richard is for the Joint Committee to put together an
Richard's issue list
got considerable response from Pat and there
Pat raised the issue of blank responses and what
sort of existentials they are (i.e, how to scope these variables
over multiple queries).
Ian was concerned about the difficulty of inference, even with
simple queries, particularly if counting is enabled. There was a
long discussion on what a query processor has to do, i.e., will the
query system be implementable at all. Richard thinks that many
queries will be simple. Several different points on this issue
The next challenge is to devise a query system that can handle the
simple cases without going off the deep end.
Richard wants responses.
We'll plan to discuss the XML Query Data Model
and further discuss Richard's issue list.
