Re: [core] 10 years of CoRE today!

Hi Carsten,
It was indeed a treasured learning experience for me to interact with you during the journey of RFC 7967 (no-response option). Unfortunately we could not got that through the WG. But it was under your Chair-ship when we were able to discuss this in the WG for significant duration over several meetings and, undoubtedly, those discussions and feed backs helped the draft smoothly pass through the independent submission track. Appreciate all the guidance you provided in tough times.

Thank you!

Thomas is right, it's 10 years now (or will be later today:
  Subject: WG Action: Constrained RESTful Environments (core)
  Date: Tue,  9 Mar 2010 11:00:02 -0800 (PST)
).  I wonder if there is a way we can have a face-to-face celebration
soon, so I'll resort to supplying some background here on the list.

The protocol work was already started in 2009 (under the name of
6lowapp) by Zach Shelby, then of Sensinode fame (acquired by ARM
later), several others, and me.  Klaus Hartke came in by 2010, first
with the Observe idea and spec, and then as a main author on the CoAP
spec itself.

http://tools.ietf.org/html/draft-bormann-6lowpan-6lowapp-problem-00 is
one of the very early documents from 2009.  We held a rather memorable
"Bar BOF" at IETF75 in Stockholm (not at a bar, but with actual beer!
-- thanks to Zach Shelby and his company) crammed in before the
social, see
http://trac.tools.ietf.org/area/app/trac/wiki/BarBofs/IETF75/6LowApp
(and of course my slide set referenced from there)
-- that was probably the most productive birthday party I ever had...

In that Bar BOF, the decision was taken to start work on an
application layer protocol for constrained node networks; the
assumption was that work on a constrained transport protocol would
take a decade (so it would be finished today :-).

We had our IETF BOF at IETF76 in Hiroshima, November 9, 2009.
On December 24th, 2009, the -00 of the requirements document was
published.  We became the CoRE WG on 2010-03-09, right before IETF77
in Anaheim.

Only 4 years after the Bar-BoF, the CoAP specification was approved
with 8 Yes votes (!) in the IESG (and then had to wait another year in
the RFC editor queue before some security area squabble was settled
that affected a normative reference).

During the ten years of the CoRE WG so far, I shared the chair
position with a number of co-chairs: Cullen Jennings to 2012, Andrew
McGregor to 2016, Jaime Jiménez since, and now Marco Tiloca as well.
Responsible ADs included Lisa Dusseault who chartered us, Peter
Saint-Andre from 2010, Barry Leiba from 2012, and Alexey Melnikov from
2016, with another handoff coming this month.  (If you want a visual:
https://ietf.org/proceedings/95/slides/slides-95-core-0.pdf#page=8 .)

In total, we have published 12 RFCs in those first ten years, one
experimental (RFC 7390 groupcomm), and 11 standards-track (among
these: RFC 6690 link-format, the core set 7252, 7641, 7959; RFC 8132
fetch/patch, RFC 8323 over TCP/TLS; RFC 8613 OSCORE).  Quite a few
more specifications are almost done or have already left the WG, being
processed by the IESG (4) or in the RFC editor queue (1).

Of course, it's the working group that is doing the work, not the WG
chairs.  But among the latter, we now have two on board that I believe
are below the IETF median age, which is a good thing going forward.

Those who have worked with me a bit longer may know that I have this
idiosyncrasy: I'm trying not to do the same thing in the same way for
more than ten years.  That is not a hard and fast rule, but it has
generally served me well.

So I'm stepping down as a CoRE WG chair today.

I'm not completely leaving the building though, sorry about that.
First, I'm staying on as shepherd on a few drafts, as you can see in
https://datatracker.ietf.org/group/core/documents/ -- right column.

But more importantly, I am a co-author on a few drafts (both in the WG
and in the related IRTF T2TRG) I really want to develop to maturity,
and I'll now be able to focus on document writing (as opposed to
managing the conflict between being a chair and a document author).

So I'll still do the same things, just not in the same way!

Grüße, Carsten
