Thanks, Hans-Peter. I agree 100%. Talk to you later today! =ppy|

I will attend the call today. In my
view it is best to first concentrate on reaching consensus on the basis
of the "master" CLIF ontology that Pat is developing, bringing
in concepts / thoughts as captured in the various OWL ontologies, i.e.
using them as a kind of check list to validate that all needed concepts
can be and are properly represented in the CLIF ontology. This is already
enough of a challenge and I think we would only confuse each other unnecessarily
by working with multiple ontology representations concurrently. Also many
concepts can be represented in different ways that are equally "correct"
but differ mainly in modeling style, where modeling style may be personal
It is important that each of us tries
to overcome / look beyond such "modeling style" issues, although
this may be hard at times, because the modeling style is often related
to the application domain of the standard. Speaking for myself, the QUDV
model for SysML is meant to support Model-Based Systems Engineering representations
and tries to be as much as possible compatible with UML2, so it is very
much oriented towards engineer end-users and much less towards experts
in formal logic / mathematical set theory.
I guess one of my challenges is to find
a way to relate (ideally through an executable formal mapping) the OWL2
DL ontology that will comply with the formal QUOMOS master ontology in
CLIF to a "QUDV next version" one that can still be understood
and effectively used by engineer end-users in a SysML context (and any
other engineering modeling languages/notations for that matter).
Best regards, Hans Peter
Dear Hans, Rob, and Chip,
I’m writing in the hope that you will be able to attend
the call on Thursday, Jan. 7 (see http://ontolog.cim3.net/cgi-bin/wiki.pl?UoM_Ontology_Standard/ConferenceCall_2010_01_07)
where we will be wrapping up the Ontolog phase of this activity in preparation
for the first official OASIS committee meeting scheduled for January 21st.
In particular, we’re hoping to hear what you might have
to say regarding the OWL draft (recognizing that it is tightly linked to
the CLIF version that Pat Hayes is working on). The call is at 6:30pm GMT,
or 10:30am PST. Hope you can make it!
