Thanks you all, Nicolas, John, MichaelM & MichaelG. How we've got
our program team together ... I bow out now, so that you can
continue the prep work. (01)
Please continue the dialog on this thread, and capture
significant progress under the ?prep page at:
http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2005_10_20 (02)
At an appropriate time, please move salient portions of that work
(confirmed panelists, abstract, framing-of-the-issues, ... a
consensus set of questions we like to address within that 2-hour
session, ... etc.) over to the session page proper, at: (03)
http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2005_10_20/Prep (04)
Feel free to solicit other suggestions and comments from the rest
of the community too. (05)
Cheers. =ppy
