Colin,

Procedurally, the IETF lacks authority over IRTF documents, just as the IETF lacks authority over IAB documents and the IETF lacks authority over Independent Submission documents.  

— This all was well understood when I was on the IAB about 20 years ago.  

— No subsequent process document has changed the above as the correct process.

That noted, the IRTF Chair (or IRSG) could make RFC-5050 (or any other IRTF track RFC) obsolete, and the IRTF process for doing so is WILDLY simpler — an email from IRTF Chair would be sufficient to make it happen.

E.g., see RFC 3940(*) and RFC 5740.  That, of course, doesn’t mean the *experiment* is “obsolete”, the experiment is done and was a great success, and has led to the standards-track protocol.

Disagree — based on the I* community's actual process documents.

However, the end result is easily accomplished, an email from you in your role as IRTF Chair would be sufficient to make RFC-5050 obsolete and would maintain compliance with the correct procedure.

To me, it is obvious that the DTN WG was set up to do exactly that, and there were a few years to stop this process if this outcome wasn’t desired.

It doesn’t seem problematic for a standards track RFC published on the IETF stream to obsolete an experimental RFC published by the IRTF, provided there’s coordination between the RFC stream managers and agreement that such a status change is appropriate. I’d expect the IESG to check with the IRTF Chair and IRSG before approving such a draft, for example.

Existing correct process would not merely “expect”, but would actually “require”, such coordination.  Further, the authority to obsolete an IRTF document procedurally rests with the IRTF Chair and/or IRSG, not with the IETF or IESG.  In practice, I imagine it is unlikely for the IESG to request anything silly of the IRTF Chair or IRSG, but PLEASE let us follow the correct process.  It is EASY to follow the correct process here.

IRTF is not a subsidiary of the IETF.  The IRTF is a subsidiary of the IAB.  The IAB also is not a subsidiary of the IETF — indeed, the IAB has to review and approve/disapprove IESG nominations coming from NOMCOM.  

And for the avoidance of doubt, that IAB review & approve/disapprove responsibility is NOT a rubber stamp.  I personally know of more than 1 case where the IAB declined to confirm a NOMCOM nomination of someone for the IESG.  I believe this is rare, but it has happened for particular cases where that decline really was the correct answer.

I assume that the ISOC folks who approve/disapprove of NOMCOM nominations for the IAB take equal care in deciding whether to approve/disapprove particular candidates.

> I’ve not read the documents in question, so I won’t comment on this specific case. 

In the specific case, I concur with the numerous folks who believe that RFC-5050 ought to be obsoleted by the publication of the standards-track RFC(s).

If the DTN WG chairs believe, after they decide this thread is finished, that there is WG consensus to obsolete RFC-5050, then I’d suggest that the DTN WG chairs ask the IRTF Chair (with CC: to the IESG) to obsolete RFC-5050 while noting the WG consensus to do so.  If that request were made, then I would hope the IRTF Chair then would do so.

It is EASY to follow the correct process here.  We need not leave the well trod path and go bushwhacking to create a new path.

Yours,

Ran
