DAML+OIL (March 2001)
Frank was swamped this week, and didn't get to update the walkthru and reference yet.
There was consensus that it was worth waiting for this to be complete.
The walkthru is critical -- the reference could potentially wait,
but we should note that it's forthcoming rather than release an out-of-date version.
Peter asked that we preserve the CVS file modification dates
when publishing the release to
http://www.daml.org/2001/03/.
ACTION (Mike): Update the nightly update script.
ACTION (Mike): Add
Dublin Core
annotations to daml+oil.daml and
daml+oil-ex.daml.
There was some discussion of which portions of the release were normative:
the reference text, the model-theoretic semantics, and/or the axiomatic semantics.
Future releases should make this clear.
It would be desirable to have someone formally check the consistency between
the model-theoretic and axiomatic semantics.
It's estimated that this would take about a week's work.
This might be a good project for a graduate student.
ACTION: Pat Hayes volunteered to try this.
Jim noted that people are using both versions of
the semantics, and believes there are advantages to keeping both
for the long term.
RESOLVED: We should generally avoid use of the .xsd suffix in namespaces
referring to built-in or user-defined XML Schema types.
Knowledge Technologies 2001
Dan Connolly made his
trip report
available.
DAML was well received.
Other highlights of the conference included:
- Cycorp
announced
OpenCyc,
which will be released in DAML.
- lots of discussion of RDF vs. Topic Maps
W3C RDF IG Meeting (continued from 27 February)
Stefan reported on the closing session of the
RDF Interest Group face-to-face meeting.
Items of particular interest to DAML:
It has been proposed that the next face-to-face meeting of the
RDF Interest Group be held in
conjunction with the
Semantic Web Workshop
at Stanford in July.
Upcoming Meetings (continued from 27 February)
The following items were suggested as possible major topics for upcoming
telecons:
- rules, including the work by the
RuleML
folks,
Tim's
Closed World Machine (cwm),
and Stefan's
Triple.
The consensus was that we'd prefer to get a formal proposal that
details integration with the current language.
- tagging and other forms of well-behaved reification.
ACTION (Jeff Heflin, Jim Hendler): write up SHOE experience.
- DAML imports
- non-monotonicity
- tools supporting DAML:
implementation experience, experimental results,
theoretical papers, algorithms, starting points,
etc.
- user perspective: what features are most important (e.g. inverse
properties vs. instances)
Next Week
ACTION (everyone): review Tim's on-going
work
with rules in N3 and cwm,
and be prepared to discuss it.
