Yes, typo.

I'm at https://datatracker.ietf.org/wg/ccamp/documents/ looking at extant WG
documents.
Looks like draft-ietf-ccamp-flexigrid-media-channel-yang expired almost 6
months ago.

Well, colour me confused.
I thought this whole thing came up in debate of the WSON YANG model.
If that debate is now closed, let's all move on and not worry about any of
this any more.

There's an information model in draft-ietf-ccamp-wson-iv-info, but no data
model.
draft-ietf-ccamp-wson-tunnel-model expired almost 6 months ago

draft-ietf-ccamp-mw-topo-yang expired almost 18 months ago

<tp>

Adrian,

The progress of I-D in the routing area can be erratic.  The fact that the IETF has expired the I-D does not mean that it will not come back to life - a whole raft of I-D that were produced in a rush just before the IETF meeting have just expired 6 months later and some are now being resuscitated, others will be in future, others will not.  Some re-appear years later when their time has come.

To me, an expired draft says that someone was interested enough to put in a lot of work and even if that work is not current, then it would be a short-sighted naming convention, although well in keeping with the traditions of the IETF, not to cater for such work in future.

For myself, I like names that start with the most important property and for me, that is WSON. OTN, RSVP and so on, and that is the basis on which I reviewed them, and not the fact that they are te - the rival proposal is for te to be the centre of the universe around which everything revolves, regardless of which WG  - TEAS, CCAMP, ... -it may be in.  I am not a fan of this approach.

Tom Petch

CCAMP is currently working on plenty of YANG models, so it might be worth
stepping back and getting the prefixes consistent across all of our work.
I'm not sure this is the most important thing on our list, and perhaps it
would be better to discuss the colour of the bike shed, but to make sure
that we do this just once, here is my attempt.

My conclusion is that, although it would be nice to be consistent with using
just a suffix of 't' to indicate 'topology', this becomes messy with some of
the longer names, and it is clearer to always use 'topo' (leaving the TE
topology model as the odd one out).

This proposal only extends to CCAMP YANG models, and I don't think this list
can debate the wider scoping of prefixes, but I think it would extend well
enough.

The list shows...
