Benoit,
You describe the situation really well, but as next step we have to get more
organized and more coordination in modeling work. We have to make sure that
there is not too much overlap between efforts, not too waste resources
... and inconsistencies between data models, which is my primary concern.
Let's take one example: policies. I see policies in many YANG models. How do we
make sure the policie definitions are consistent and extensible? How can we
coordinate this (huge) effort? Who is in charge? The collective responsibility
might not be enough…
Coordination is only one issue: its operational efficacy that is also of
paramount importance here. We should do what we’ve done in NETMOD's “design
teams”: pair up people that are truly implementing functionality in real or
virtual devices with operators to ensure that the models created are grounded
in the realities of implementation and deployment.
I agree with you on operational efficacy, but as there are more and more
models, I see some duplication work, so I really see a need to get a meta
architecture asap, so that the teams can be more efficient.

and as well create an architecture description document, where the relationship
between models will be described. With that we can see which models can be
reused as base model in other models.
Good example of coordination is the rtg-coord-yang mailing list, but we need
one for all IETF, to be able to find what are other the teams working on.
Right.
Regards, Benoit
We should not let this momentum go away and with few simple steps (like
improving coordination and system meta architecture), continue to feed positive
energy into this situation.
