All,

Picking up on Juergen's comment:

I agree that the objects should be defined in a separate module.  The
request, as I understand it, is for there be an "ietf-hardware-state"
module defined in the Appendix of this draft.  I believe that doing
so is consistent with the NMDA guidelines:

   (b) Models that require immediate support for "in use" and "system
   created" information SHOULD be structured for NMDA.  A non-NMDA
   version of these models SHOULD exist, either an existing model or a
   model created either by hand or with suitable tools that mirror the
   current modeling strategies.  Both the NMDA and the non-NMDA modules
   SHOULD be published in the same document, with NMDA modules in the
   document main body and the non-NMDA modules in a non-normative
   appendix.  The use of the non-NMDA model will allow temporary
   bridging of the time period until NMDA implementations are available.

Of course, we should ask, for how long is it that the IETF (SDOs in 
general) should publish these -state modules?   During the discussion
at the beginning of the first session in Singapore, I said something
along the lines of "so long as there is market demand for it", which
seems a bit too open-ended for my taste.   I recommend that we set a 
date, perhaps a couple years out, after which we (the IETF) will no 
longer publish or maintain such foo-state modules.

Thoughts?

===== original message ======

Bart,

I think the reason for the difference is that the interfaces model was
published as an RFC before while the hardware model is new and hence
it seems to look a bit odd to define new deprecated objects.

If these deprecated objects are essential for BBF (please confirm),
then it might be better to define them in a separate module that then
can silently die while systems move to NMDA (and so we do not have the
deprecated objects with us in the hardware module forever - or at
least as long as we use YANG 1.1).
