status of the group

Friends of Modeling:

I haven't seen much traffic on the list other than a few postings last
week. Would someone comment on the status of the group?

In addition to the comments I made last week about TINA/ODP, I also
direct your attention to the SIP/IN interworking initiative ongoing at
IETF. As long as that's still alive, we might as well consider where IN
is heading, namely, TINA. If a NIM is to be developed, it might be a
Good Thing for it to comprehend IN and TINA.

On one axis TINA has four architectures: services/applications, network
infrastructure, computing/middleware, and management. On the other there
are five models and languages in ODP: business/enterprise,
informational, computational, engineering, and technology. Then consider
the 4x5 matrix formed from those two axes. That makes for a lot of
(sub)models. Not that NIM has to use them all but at least we can be
aware of them, use what we can and throw away the rest.  There's no need
to reinvent the wheel ...

BTW there are at least five other axes to consider before we launch a
NIM, one of which is the use of formal methods like first-order theories
and mathematical specification languages, specifically Object Z. But I
suppose we can wait for a more appropriate time to broach that subject
...

--Cheers, TS
