Hi Tom,

If memory serves me well originally we had the optical-path-computation draft only, and then we asked the authors to split into optical and OTN drafts.
That should be right since the optical draft was first uploaded in Oct 2022 while the OTN draft in Jun 2022, but please correct me if I'm wrong.

In the Datatracker it's possible to mark a draft as the replacement of another. That's usually done in the adoption process but saying that an individual document replaces another individual document is less common.
Nevertheless we can do that if there is such need.

My problem here would be to say which draft replaces which one. The OTN doesn't replace the original optical draft, it has just been branched from it but doesn't replace it. Neither does the optical one, which is just an evolution of the original draft with the OTN part being removed.

What are you suggesting as a name change once/if the drafts will be adopted?

<tp>
My primary concern is that if an AD or anyone else wants to track the history of the YANG module for OTN, then there is nothing in draft-gbb-ccamp-otn-path computation-00 or anything thereafter to say that this unadopted -00 is not the first version of the YANG module - which as I said I have seen ADs stumble over.
So my first concern is that such text is present in draft-ietf-ccamp-otn-path-computation up to and including Last Call (since I cannot see a good way of putting this detail into the datatracker).  If this means generating a -03 to include the text before adoption, then yes, that works for me.:-)

My lesser concern is that optical-path-computation has lost one third of its content with no explanation why so I think that that I-D also needs text adding to explain that.  I normally dislike name changes at adoption since they make it hard to track development but here, it would for me point out that there has been a substantial change since the pre-adoption -00.

At present it is all very obvious - a year or two down the line an AD might be hunting through minutes to find out why who did what.

<tp>
ps
I went back to the minutes to see what they said since I read them at the time and would have expected to notice a split of  an I-D with multiple YANG modules.

IETF114  talks of keeping alignment but not of the split.
IETF113 talks of the number of documents being decided by dependency but does not for me suggest a consensus.

Anyhow, I think that an AD looking for a reason would be disappointed which is fine, it just makes me keener on having something in the I-Ds themselves e.g. in ccamp-otn-path-computation-yang

'This YANG module was first published in 
draft-gbb-ccamp-optical-path-computation-yang-00 '
