Hi Lada,

I still think that it makes sense to do YANG Next, on the assumption that it
will take a couple of years to work out, maybe longer if the work doesn't
properly get started until the YANG versioning work has progressed further.

When I look at the YANG Next issue list, I think that there are quite a lot
of things on that list (some of which are quite small) that would be good to
do, and will help modelling efforts.

Thanks,
Rob

Subject: [netmod] YANG next

Hi,

this morning I attended the side meeting "Next Step of IETF YANG". I was
somewhat misled into thinking that it would be about future evolution of
YANG the language, which was not the case at all. However, my personal
conclusion from the meeting is that it would be a total disaster to throw in
a new version of YANG within the next few years or so.

The operators and equipment vendors are busy putting together YANG modules
and tools, filling the gaps, coping with NMDA, schema mount, IETF versus
OpenConfig etc. A new YANG version (and modules written in it) would IMO be
extremely counter-productive at this rather turbulent stage.

So, if we want to continue the yang-next discussion, I think we first have
to figure out how to evolve YANG without making waves in the current YANG
pond and let the operators and vendors do their work, without which YANG can
never succeed.

Lada
