Proposed Standard

> Why is this the proper type of RFC?

The document defines a YANG module.

> Is this type of RFC indicated in the title page header?

Yes

> (2) The IESG approval announcement includes a Document Announcement

>   an indication that there are deficiencies in the abstract 
>   or introduction.


   This document defines a collection of common data types and groupings
   in YANG data modeling language.  These derived common types and
   groupings are intended to be imported by modules that model Traffic
   Engineering (TE) configuration and state capabilities.


> Working Group Summary
>   Was there anything in WG process that is worth noting? For 
>   example, was there controversy about particular points or 
>   were there decisions where the consensus was particularly 
>   rough?

This document was split from the draft-ietf-teas-yang-te to faciliate
document references and interdependencies that are not linked to TE
Tunnels and Interfaces, e.g., draft-ietf-teas-yang-te-topo.  There is
strong interest in this document and seeing it progress.

> Document Quality
>   Are there existing implementations of the protocol? Have a 
>   significant number of vendors indicated their plan to 
>   implement the specification? Are there any reviewers that 
>   merit special mention as having done a thorough review, 
>   e.g., one that resulted in important changes or a 
>   conclusion that the document had no substantive issues? If 
>   there was a MIB Doctor, Media Type or other expert review,

The YANG module document is critical to other TE YANG modules.  Multiple
vendors have stated that they are implementing the dependent modules.
This draft has gone through a YANG Doctor review.

I have reviewed this work as it progressed, from the start of when it
was adopted until the recent WG Last call. I believe it is ready for
publication.

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

No.

> (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.

Yes, the document should and has been reviewed by the YANG doctor
team.  The review comments were addressed in the current version of the
draft.

> (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.

No issues.

> (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.

Yes. See
https://mailarchive.ietf.org/arch/msg/teas/EIksux939vJ_1l8486PYwoFocqs


> (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?   

I think it represent strong consensus among thos in the WG interested in
and working on YANG.

> (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 https://www.ietf.org/tools/idnits/ and the Internet-Drafts
> Checklist). Boilerplate checks are not enough; this check needs to be
> thorough.

None.

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

An early YANG doctor review was requested and the document was updated
based on the received comments.

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

Yes.

> (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?

None.

> (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.

> (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 section was fully reviewed and contains the information
typically included for a new YANG module.

> (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.

Node.

> (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.

YANG validation was reviewed and is available at:
