Hi Akbar,

Talk to your chairs and consider that the requirements went from 
publication requested (i.e., on the way to the IESG) back to the WG 
(i.e., not on the way to the IESG).

The same is true for the architecture draft.

> - We did have one lunch meeting in Vancouver with Martin and the chairs but that was publicly announced and open to all in the WG.  At that meeting, I recall Martin asking the attendees if there was industry interest for the DECADE work.  From what I recall, everyone there did express various levels of interest and support.  I didn’t hear anyone say that DECADE was a "wasted effort". So, frankly I was surprised and disappointed to see the WG shut down so suddenly.  If there really is no community support to continue with the activity, then so be it.  But you cannot conclude that there is not interest without first having an open discussion.

To be honestly, but expressing interest and transforming interest to 
technical progress are two very distinct actions.

I have seen a lot of 'expressing interest', but the technical progress 
was and is just not there.

I also told at the lunch meeting in Vancouver that I want to see actions 
on the two main drafts in the WG, i.e., the requirements and the 
architecture. Yes there has been action, but the technical quality of 
the drafts is far from being useful for any further protocol development.
See also my email with 2 examples on issues not addressed in neither the 
requirements nor the architecture draft.

> - In terms of the document quality.  The first draft of the Architecture I-D was in March 2011.  Since then we have gotten extensive comments from various excellent reviewers.  But as is often the case when you have multiple reviewers, you sometimes get conflicting directions.  Some reviewers wanted a high level abstract architecture that avoided all "implementation" details.  Other reviewers wanted a more detailed approach that got more into the details of the protocols and inner workings of the nodes.  I personally tried in a good faith effort to address all the comments and to try to strike a balance in addressing the philosophies of the different reviewers.

The architecture drafts clearly fails to show the architecture of the 
DECADE protocols. See my AD review.

You have indeed received extensive reviews, but it is up to date not 
clear if and how they were addressed.

You can see also this, as the draft talks about the DECADE system which 
is not equal to the protocols.

> - I agree with Kostas that many documents in other WGs go through similar issues but at the end still managed to produce good work.

Yes and no. There are examples in both directions, so it doesn't help 
here in this particular case.

> - To conclude, I devoted in good faith a fair amount of my energy to participate in advancing the topics in the WG since the first session back in Anaheim.  I defer to the higher powers to make the decision on closing the DECADE WG or not.  However, I clearly want to state that I think it was unfortunate to also suddenly terminate the DECADE Architecture I-D which was being extensively revised whenever we got reviewer comments.  I understand if people are saying that more work has to be done to get it to publication state.  But that does not warrant, in my opinion, to just shut down the work.  Honestly, if you use that criteria there would be many WG documents in other groups that should also be abruptly shut down.

I wonder why there is so much care about other groups? This is about 
DECADE not any other arbitrary group somewhere else.

With respect to the energy:
If people still believe in DECADE, take the documents, address the 
reviews, get reviews and go for the Independent Stream submission with 
the RFC editor.

It's too late and, in the end, irrelevant at this stage. But there's an order of magnitude more people on this mailing list than in the author line of all drafts together. I would consider this a breakdown in communication between the inner- and outer-circle. This was far from what, in general, I would call a "graceful teardown".
