        Document Writeup for Working Group Documents

        As required by RFC 4858, this is the current template for the Document Shepherd Write-Up.

        Changes are expected over time. This version is dated 24 February 2012.

        (1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header?

Standards Track.  While this is a simple registration of a response
code, proper usage of this response code influences interoperability.

        (2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections:

        Technical Summary:

   A CoAP server can experience temporary overload because one or more
   clients are sending requests to the server at a higher rate than
   the server is capable or willing to handle.  This document defines
   a new CoAP Response Code for a server to indicate that a client
   should reduce the rate of requests.

        Working Group Summary:

While this seemed to be a simple housekeeping document (based on other
SDOs' requests) at first, the WG process did unearth a few fine points
that have been taken care of in the current document.  WGLC was passed
July 16, 2018 (right before the CoRE meeting in Montreal), there was
no dissent on advancing this.

        Document Quality:

While no formal review was sent to the list, both Jim Schaad and Klaus
Hartke sent comments based on an in-depth review and later indicated
that their comments had been resolved in -04.  Implementers indicated
intent to implement this.  No formal languages in the document.

        Personnel:

        Who is the Document Shepherd? Who is the Responsible Area Director?

* Shepherd: Carsten Bormann
* Responsible AD: Alexey Melnikov

        (3) Briefly describe the review of this document that was performed by the Document Shepherd. If this version of the document is not ready for publication, please explain why the document is being forwarded to the IESG.

Shepherd did review ahead of WGLC and followed the comments and their resolution.

        (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed?

For the simple document this is, review was quite appropriate.

        (5) Do portions of the document need review from a particular or from broader perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that took place.

N/A

        (6) Describe any specific concerns or issues that the Document Shepherd has with this document that the Responsible Area Director and/or the IESG should be aware of? For example, perhaps he or she is uncomfortable with certain parts of the document, or has concerns whether there really is a need for it. In any event, if the WG has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here.

Shepherd is comfortable with this going forward.

        (7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why?

Author declared "I'm not aware of any IPR related to
draft-ietf-core-too-many-reqs." in E-Mail to WG chairs on July 24.

        (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures.

No.

        (9) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it?

Of the people who care about the area addressed in this document,
everyone agreed this should go forward.

        (10) Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarise the areas of conflict in separate email messages to the Responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.)

No.

        (11) Identify any ID nits the Document Shepherd has found in this document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough.

No ID nits found.

        (12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, media type, and URI type reviews.

While there were no formal review criteria, the response code
registration was discussed with the designated expert for other CoAP
parameters, who assented.

(The policy for this registry is

   The IANA policy for future additions to this sub-registry is "IETF
   Review or IESG Approval" as described in [RFC5226].

as per section 12.1.2 of RFC 7252; we still like to make sure that all
registrations to CoRE are being looked at by a single DE.)

        (13) Have all references within this document been identified as either normative or informative?

Yes, and correctly so.

        (14) Are there normative references to documents that are not ready for advancement or are otherwise in an unclear state? If such normative references exist, what is the plan for their completion?

No.

        (15) Are there downward normative references references (see RFC 3967)? If so, list these downward references to support the Area Director in the Last Call procedure.

No.

        (16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in the Abstract and Introduction, explain why, and point to the part of the document where the relationship of this document to the other RFCs is discussed. If this information is not in the document, explain why the WG considers it unnecessary.

No; this is just a registration to an existing registry (from RFC 7252).

        (17) Describe the Document Shepherd's review of the IANA considerations section, especially with regard to its consistency with the body of the document. Confirm that all protocol extensions that the document makes are associated with the appropriate reservations in IANA registries. Confirm that any referenced IANA registries have been clearly identified. Confirm that newly created IANA registries include a detailed specification of the initial contents for the registry, that allocations procedures for future registrations are defined, and a reasonable name for the new registry has been suggested (see RFC 5226).

The main point of this document is the IANA registration of a response
code for CoAP.

        (18) List any new IANA registries that require Expert Review for future allocations. Provide any public guidance that the IESG would find useful in selecting the IANA Experts for these new registries.

No new registries (just a registration to an existing registry).

        (19) Describe reviews and automated checks performed by the Document Shepherd to validate sections of the document written in a formal language, such as XML code, BNF rules, MIB definitions, etc.

No formal languages.
