RE: [nmrg] RE: Proposed IETF Working Group: sming

["Wijnen, Bert (Bert)" <bwijnen@lucent.com>]

Dave, I am answering this email... but please for further 
discussions, use sming@ops.ietf.org. To subscribe, send
email to majordomo@psg.org, in body say: subscribe sming

Dave, if you want to discuss this further with OPS ADs or IESG
in general, then of course you can also send email to Rany and/or
myself and/or to the iesg@ietf.org mailing list.

The Information Modeling you talk about is a topic of the NIM BOF.
That work has not been defined well enough yet to start a new WG.
We are proposing to move SMI forward to address some of the
issues that have been raised in the last so many years.

Your input for both NIM discussions and for the potential sming WG
are of course very wellcome.

Below, I see that your focus is on CMIP and CORBA.
Our focus for now is on SNMP and COPS.

During the NIM BOF, I heard a lot of scepticism about the feasibility
of trying to define one Information Model that would be able to 
handle all the different technologies and at the same time be
compatible with all the exitsing models.
