Shepherd writeup

Writeup for draft-ietf-mpls-ldp-yang-06.txt

(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?

Proposed Standard - Standards Track indicated on the title page.
This RFC is intended to define a YANG module to manage the MPLS LDP protocol.

(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

From the Abstract:
This document describes a YANG data model for Multi-Protocol Label
Switching (MPLS) Label Distribution Protocol (LDP).  The model also
serves as the base model to define Multipoint LDP (mLDP) model.

Working Group Summary

The Working Group has reached consensus that this document is useful and should be published. This document went through multiple reviews within the working group over the course of its development. Multiple revisions were done as part of making the module adhere with the NMDA structure.
The current document represents a proper management framework for the most commonly deployed MPLS LDP features covered in various RFCs. The design of this module also takes future extensions/augmentations into considerations.
Document Quality

Expert review was done by YANG Doctors and by multiple WG members. All comments have been addressed, and there are currently no open issues. 


Tarek Saad is the Document Shepherd.
Deborah Brungard is the Responsible Area Director.

(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.

The document shepherd has reviewed the specification during WG last call and subsequently checked all diffs. Comments on the mailing list were addressed in the last version. The document shepherd believes that the document is ready for publication.

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

The shepherd has no concerns about the depth and breadth of the reviews that were performed.

(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.

The document still needs to be reviewed by the relevant directorates

(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.

The shepherd does not have any concerns about the document.

(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.


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

Yes. There were no specific discussions or conclusions in the WG.

(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?   

There is consensus of all people who have reviewed and contributed to the document.

(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.) 


(11) Identify any ID nits the Document Shepherd has found in this
document. (See and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be

None errors found.
2 warnings for longer pages exceeding 58 lines per page.
1 warning for document not using any RFC 2119 keywords, yet RFC 2119 boilerplate text.
a number of warnings due to "line has weird spacing:" - it's not clear what's the warning about. It seems a tool issue
1 outdated informational reference: A later version (-06) exists of draft-ietf-mpls-mldp-yang-05
These nits should be addressed the next time the document is updated.

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

Appropriate expert reviews, including Yang doctors, have been done.

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

(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?


(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. 


(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.

There will be no status change of any other documents when this document is published.

(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 IANA considderation are clearly stated in the document.

(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 IANA registries are being defined.

(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 reviews necessary.
