Charter and Committee Evolution
Mike Dean presented a draft
charter for the committee.
Tim Berners-Lee and Dan Connolly shared the
Semantic Web Activity proposal
After considerable discussion,
our current plan is
The W3C groups probably won't be formed before March 2001.
Most of our activity until then will be focused on
preparing our current work for transition.
In particular, our "Rules Subcommittee" will be put on hold.
- We anticipate that W3C will convene a Working Group (probably the RDF Schema Working Group)
to develop an ontology language
- We will package up our
then-current language specification (more below) and contribute it to the
- We anticipate that W3C will convene a public Interest Group (probably www-rdf-logic)
to focus longer-term on rules and logic.
- We will proceed in parallel with the
providing it with drafts and experimental results as they become available.
Many committee members are likely to join the Interest Group.
Since the W3C Interest Group would be public,
membership in the Joint Committee can be limited to government funded
US and EU Semantic Web participants plus invited experts.
Other groups and activities may similarly contribute to the W3C Interest Group.
Many people felt we should still have a charter.
This will be developed as plans unfold (schedule TBD).
There was consensus that the committee should be able to invite
others to join the committee.
Those present voted unanimously to invite Peter Patel-Schneider to join the committee.
We will package a "major" language release over the next couple weeks.
The name DAML+OIL was chosen to acknowledge the major contributors
while differentiating the result from the previous DAML-OIL proposal.
- DAML+OIL will primarily consist of the DAML-OIL proposal as modified by committee discussion.
- Synonyms for RDF/RDFS Property and Class and so forth
will appear in the DAML+OIL namespace,
but "best practice" may dictate to refer to the original namespaces.
These synonyms may be deprecated as XML Namespace mechanisms evolve.
- Both Frank's
presentation syntax (link TBD)
and Dan's n4 presentation syntax (link TBD)
will be included as examples,
but neither will be made official.
- Updated versions of the formal semantics developed by
Deb McGuinness and Richard Fikes
Ian Horrocks and Peter Patel-Schneider
will be included,
but neither will be made official.
- DAML+ONT is not expected to include on-going work with concrete types.
Ian Horrocks will serve as editor for the DAML+OIL release.
All committee members will be listed as co-authors.
Since roles are evolving slightly,
we'll merge the Editors and Members lists
DAML+OIL is expected to be the last major release until we package
a contribution for the W3C Working Group.
We will proceed with our normal Tuesday telecon schedule through
except that there will be no telecon on Tuesday, 26 December 2000.
