Tom:

Would you like me to check with the NM/OPS AD as well on this point?
They
may have an agreement with the IEEE folks on yang models.

<tp>

Sue

Yes please.

I have posted to Netmod where Rob Wilton thinks that it is fine and
copied it to Scott Mansfield.  My unease is rather vague that the IETF
and IEEE may take separate paths, on YANG, at some point. I see this not
as technical, where IEEE clearly have the skills in 802, but rather as
political or management, noting that the tools do not cope with this, as
Qin has found, that the module does not appear in the IANA registry (and
cannot from 802.1Q as it is RFC Required), that Rob sees the reference
as 801.1Qcp and not 802.1Q and so on.  We are making the IETF dependent
on something we have no control and little influence over.

I would like an AD to say that they can see the issues and are content
that there will be no problem in future (I may turn round in five years
time and say 'I told you so' but that is business as usual, for me).

Tom Petch

Cheerily, Sue

Qin

You had a note in -07 about whether or not to import definitions from
draft-ietf-softwire; and now I see that -09 imports definitions from
IEEE
802.1Q.

Um.  Different.

I have seen this before but in an I-D that AFAICT never progressed.

I am uncertain what the implications of this are, in terms of the
evolution
of the model, of the YANG language and so on, given the different
philosophies of the IETF and IEEE.  I think that it needs a wider review
than it will get on this list so I will flag this to NETMOD and perhaps
again at IETF Last call.
