Joint Committee Minutes 7-8 December 2000

This page summarizes the meeting of the Joint US/EU Committee on Agent Markup Languages held at the BBN Rosslyn office on Thursday, 7 December 2000, and Friday, 8 December 2000. These minutes were prepared by the chairman, and were approved during the 19 December telecon.

Discussion details and action items can be found in the Links below.



Key contributors to SHOE, RDF, and OIL presented some of their retrospective and lessons learned, focusing on material not already in the published literature:


Ian Horrocks gave a demo of OilEd.

Deb McGuinness gave a demo of Chimaera's diagnostics for DAML-ONT and OIL ontologies.

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 from W3C. After considerable discussion, our current plan is
  1. We anticipate that W3C will convene a Working Group (probably the RDF Schema Working Group) to develop an ontology language
  2. We will package up our then-current language specification (more below) and contribute it to the Working Group
  3. We anticipate that W3C will convene a public Interest Group (probably www-rdf-logic) to focus longer-term on rules and logic.
  4. We will proceed in parallel with the Interest Group, 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.
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.

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.

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 on

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 the holidays, except that there will be no telecon on Tuesday, 26 December 2000.
