Abstract

   This document describes methodologies that have been designed to
   improve and facilitate IETF document flow processing.  It specifies a
   set of procedures under which a working group chair or secretary
   serves as the primary Document Shepherd for a document that has been
   submitted to the IESG for publication.  Before this, the Area
   Director responsible for the working group has traditionally filled
   the shepherding role.

RFC 4858          Document Shepherding to Publication           May 2007


1.  Introduction

   Early in 2004, the IESG undertook several experiments aimed at
   evaluating whether any of the proposed changes to the IETF document
   flow process would yield qualitative improvements in document
   throughput and quality.  One such experiment, referred to as the
   "PROTO process" or "PROTO" (because it was created by the "PROcess
   and TOols" or PROTO [PROTO] team), is a set of methodologies designed
   to involve working group chairs or secretaries more directly in their
   documents' approval life cycle.  In particular, the PROTO team
   focused on improvements to the part of a document's life cycle that
   occurs after the working group and document editor have forwarded it
   to the IESG for publication.

   By the end of 2004, the IESG had evaluated the utility of the PROTO
   methodologies based on data obtained through several pilot projects
   that had run throughout the year, and subsequently decided to adopt
   the PROTO process for all documents and working groups.  This
   document describes this process.

   The methodologies developed and piloted by the PROTO team focus on
   the working group chair or secretary as the primary Document
   Shepherd.  The primary objective of this document shepherding process
   is to improve document-processing throughput and document quality by
   enabling a partnership between the Responsible Area Director and the
   Document Shepherd.  In particular, this partnership has the explicit
   goal of enfranchising the Document Shepherd while at the same time
   offloading a specific part of the follow-up work that has
   traditionally been responsibility of the Responsible Area Director.
   The Responsible Area Director has tens or many tens of documents to
   follow, while the Document Shepherd has only a few at a time.
   Flowing the responsibility to the working group level can ensure more
   attention and more timely response.

   Consequently, the document shepherding process includes follow-up
   work during all document-processing stages after Working Group Last
   Call, i.e., during AD Evaluation of a document, during IESG
   Evaluation, and during post-approval processing by IANA and the RFC
   Editor.  In these stages, it is the responsibility of the Document
   Shepherd to track and follow up on feedback received on a document
   from all relevant parties.

   The Document Shepherd is usually a chair of the working group that
   has produced the document.  In consultation with the Responsible Area
   Director, the chairs may instead decide to appoint the working group
   secretary as the responsible Document Shepherd.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in BCP 14, RFC 2119
   [RFC2119].

3.  Process Description

   The document shepherding process consists of the following tasks:

   o  Providing the Document Shepherd Write-Up accompanying a document
      that is forwarded to the IESG when publication is requested, as
      described in Section 3.1.

   o  During AD Evaluation of the document by the Responsible Area
      Director, managing the discussion between the editors, the working
      group, and the Responsible Area Director, as described in
      Section 3.2.

   o  During an IETF Last Call, if performed for the shepherded
      document, following up on community feedback and review comments.

   o  During IESG Evaluation, following up on all IESG feedback
      ("DISCUSS" and "COMMENT" items) related to the shepherded
      document, as described in Section 3.3.

   o  Following up on IANA and RFC Editor requests as described in
      Section 4 and Section 5.

   The shepherd must keep the document moving forward, communicating
   about it with parties who review and comment on it.  The shepherd
   must obtain the working group's consensus for any substantive
   proposed changes.  The shepherd is the leader for the document and
   for the working group, and maintains a critical and technical
   perspective.  In summary, the Document Shepherd continues to care for
   a shepherded document during its post-WG lifetime just as he or she
   has done while responsible for the document in the working group.

   Before any document shepherding takes place, a single Document
   Shepherd MUST be identified for a document (he or she will be named
   in the Document Shepherd Write-Up).  Frequently, the chairs and the
   Responsible Area Director will decide that the working group will
   adopt the PROTO process for all their future documents.  After that
   decision, the chairs, in consultation with the Responsible Area
   Director, decide on who should act as Document Shepherd for any given
   document.  This is typically and by default one of the chairs of the
   working group.  In consultation with the Responsible Area Director,



Levkowetz, et al.            Informational                      [Page 4]
^L
RFC 4858          Document Shepherding to Publication           May 2007


   the chairs MAY also decide to appoint the working group secretary as
   Document Shepherd for a given document.  The Document Shepherd SHOULD
   NOT be an editor of the shepherded document.

   It is intended that the Document Shepherd role be filled by one
   person during the entire shepherding process.  However, situations
   may occur when the Document Shepherd role may be reassigned to
   different persons during the lifetime of a document.  It is up to the
   chairs and Responsible Area Director to identify situations when this
   may become necessary, and then consult to appoint a new Document
   Shepherd.

   It is important to note that the document shepherding process only
   applies to documents that are the product of a working group.  It
   does not apply to documents that originate elsewhere.  Additionally,
   Section 6 discusses other instances in which the document shepherding
   process does not apply.

3.1.  Document Shepherd Write-Up

   When a working group decides that a document is ready for submission
   to the IESG for publication, it is the task of the Document Shepherd
   to complete a "Document Shepherd Write-Up" for the document.

   There are two parts to this task.  First, the Document Shepherd
   answers questions (1.a) to (1.j) below to give the Responsible Area
   Director insight into the working group process that applied to this
   document.  Note that while these questions may appear redundant in
   some cases, they are written to elicit information that the
   Responsible Area Director must be aware of (to this end, pointers to
   relevant entries in the WG archive are helpful).  The goal here is to
   inform the Responsible Area Director about any issues that may have
   come up in IETF meetings, on the mailing list, or in private
   communication that they should be aware of prior to IESG Evaluation
   of the shepherded document.  Any significant issues mentioned in the
   questionnaire will probably lead to a follow-up discussion with the
   Responsible Area Director.

   The second part of the task is to prepare the "Document Announcement
   Write-Up" that is input both to the ballot for the IESG telechat and
   to the eventual IETF-wide announcement message.  Item number (1.k)
   describes the elements of the Document Announcement Write-Up.

   Some examples of Document Announcement Write-Ups are included in
   Appendix A, and there are many more examples with subject lines such
   as "Protocol Action" and "Document Action" in the IETF-announce
   mailing list archive.

RFC 4858          Document Shepherding to Publication           May 2007


   The initial template for the Document Shepherd Write-Up is included
   below, but changes are expected over time.  The latest version of
   this template is available from the IESG section of the IETF web
   site.

   (1.a)  Who is the Document Shepherd for this document?  Has the
          Document Shepherd personally reviewed this version of the
          document and, in particular, does he or she believe this
          version is ready for forwarding to the IESG for publication?

   (1.b)  Has the document had adequate review both from key WG members
          and from key non-WG members?  Does the Document Shepherd have
          any concerns about the depth or breadth of the reviews that
          have been performed?

   (1.c)  Does the Document Shepherd have concerns that the document
          needs more review from a particular or broader perspective,
          e.g., security, operational complexity, someone familiar with
          AAA, internationalization, or XML?

   (1.d)  Does the Document Shepherd have any specific concerns or
          issues 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.  Has an IPR disclosure related to this document
          been filed?  If so, please include a reference to the
          disclosure and summarize the WG discussion and conclusion on
          this issue.

   (1.e)  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?

   (1.f)  Has anyone threatened an appeal or otherwise indicated extreme
          discontent?  If so, please summarize the areas of conflict in
          separate email messages to the Responsible Area Director.  (It
          should be in a separate email because this questionnaire is
          entered into the ID Tracker.)

   (1.g)  Has the Document Shepherd personally verified that the
          document satisfies all ID nits?  (See
          http://www.ietf.org/ID-Checklist.html and
          http://tools.ietf.org/tools/idnits/.)  Boilerplate checks are
          not enough; this check needs to be thorough.  Has the document

^L
RFC 4858          Document Shepherding to Publication           May 2007


          met all formal review criteria it needs to, such as the MIB
          Doctor, media type, and URI type reviews?  If the document
          does not already indicate its intended status at the top of
          the first page, please indicate the intended status here.

   (1.h)  Has the document split its references into normative and
          informative?  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
          strategy for their completion?  Are there normative references
          that are downward references, as described in [RFC3967]?  If
          so, list these downward references to support the Area
          Director in the Last Call procedure for them [RFC3967].

   (1.i)  Has the Document Shepherd verified that the document's IANA
          Considerations section exists and is consistent with the body
          of the document?  If the document specifies protocol
          extensions, are reservations requested in appropriate IANA
          registries?  Are the IANA registries clearly identified?  If
          the document creates a new registry, does it define the
          proposed initial contents of the registry and an allocation
          procedure for future registrations?  Does it suggest a
          reasonable name for the new registry?  See [RFC2434].  If the
          document describes an Expert Review process, has the Document
          Shepherd conferred with the Responsible Area Director so that
          the IESG can appoint the needed Expert during IESG Evaluation?

   (1.j)  Has the Document Shepherd verified that sections of the
          document that are written in a formal language, such as XML
          code, BNF rules, MIB definitions, etc., validate correctly in
          an automated checker?

   (1.k)  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
             Relevant content can frequently be found in the abstract
             and/or introduction of the document.  If not, this may be
             an indication that there are deficiencies in the abstract
             or introduction.








Levkowetz, et al.            Informational                      [Page 7]

RFC 4858          Document Shepherding to Publication           May 2007


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

          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,
             what was its course (briefly)?  In the case of a Media Type
             Review, on what date was the request posted?

          Personnel
             Who is the Document Shepherd for this document?  Who is the
             Responsible Area Director?  If the document requires IANA
             experts(s), insert 'The IANA Expert(s) for the registries
             in this document are <TO BE ADDED BY THE AD>.'

   The Document Shepherd MUST send the Document Shepherd Write-Up to the
   Responsible Area Director and iesg-secretary@ietf.org together with
   the request to publish the document.  The Document Shepherd SHOULD
   also send the entire Document Shepherd Write-Up to the working group
   mailing list.  If the Document Shepherd feels that information which
   may prove to be sensitive, may lead to possible appeals, or is
   personal needs to be written up, it SHOULD be sent in direct email to
   the Responsible Area Director, because the Document Shepherd Write-Up
   is published openly in the ID Tracker.  Question (1.f) of the
   Write-Up covers any material of this nature and specifies this more
   confidential handling.

   The Document Shepherd Write-Up is entered into the ID Tracker
   [IDTRACKER] as a "Comment".  The name and email address of the
   Document Shepherd are entered into the ID Tracker, currently as a
   "Brief Note" (this may change in the future).  The email address of
   the Document Shepherd MUST also be added to the "State or Version
   Change Notice To" field (typically the email addresses of all working
   group chairs, authors, and the secretary will be added).

   Entering the name and email of the Document Shepherd into the ID
   Tracker is REQUIRED to ensure that he or she will be copied on the
   email exchange between the editors, chairs, the IESG, the IESG
   secretariat, IANA, and the RFC Editor during the review and approval
   process.  There are still manual steps required for these parties to



Levkowetz, et al.            Informational                      [Page 8]
^L
RFC 4858          Document Shepherding to Publication           May 2007


   ensure that they include the Document Shepherd, but it is hoped that
   in the future, automated tools will ensure that Document Shepherds
   (and others) receive necessary communications.

   The contact information for the Document Shepherd is also important
   for the Gen-ART team [GEN-ART], area directorates, and other review
   teams, so they can know to whom to address reviews, in addition to
   the Responsible Area Director.

3.2.  Document Shepherding during AD Evaluation

   The steps for document shepherding during AD Evaluation are as
   follows:

   (2.a)  The Responsible Area Director reads, evaluates, and comments
          on the document, as is the case when not using the document
          shepherding process.  If the Responsible Area Director
          determines that the document is ready for IESG Evaluation, he
          or she indicates this to the Document Shepherd and the
          document shepherding process continues as described in
          Section 3.3.

   (2.b)  If the Responsible Area Director has identified issues with a
          document that must be addressed before IESG Evaluation can
          commence, he or she sends a full evaluation to the Document
          Shepherd and SHOULD also enter the review into the ID Tracker.

   (2.c)  The Document Shepherd reads the AD Evaluation comments, making
          very certain that all comments are understood, so that it is
          possible to follow up on them with the editors and working
          group.  If there is some uncertainty as to what is requested,
          this SHOULD be resolved with the Responsible Area Director.

   (2.d)  The Document Shepherd sends the AD Evaluation comments to the
          editors and to the working group mailing list, in order to
          have a permanent record of the comments.  It is RECOMMENDED
          that the Document Shepherd solicit from the editors an
          estimate on when the required changes will be completed and a
          revised document can be expected.  Working groups that use
          issue tracking SHOULD also record the issues (and eventually
          their resolution) in their issue tracker.

   (2.e)  During the production of a revised document that addresses the
          AD Evaluation comments, it is RECOMMENDED that the editors
          keep a list showing how each comment was addressed and what
          the revised text is.  It is RECOMMENDED that this list be
          forwarded to the Responsible Area Director together with the
          revised document.



Levkowetz, et al.            Informational                      [Page 9]
^L
RFC 4858          Document Shepherding to Publication           May 2007


   (2.f)  In the event that the editors or working group disagrees with
          a comment raised by the Responsible Area Director or has
          previously considered and dismissed the issue, the Document
          Shepherd MUST resolve the issue with the Responsible Area
          Director before a revised document can be submitted.

   (2.g)  The Document Shepherd iterates with the editors (and working
          group, if required) until all outstanding issues have been
          resolved and a revised document is available.  At this point,
          the Document Shepherd notifies the Responsible Area Director
          and provides him or her with the revised document, the summary
          of issues, and the resulting text changes.

   (2.h)  The Responsible Area Director verifies that the issues he or
          she found during AD Evaluation are resolved in the revised
          version of the document by starting the process described in
          this section at step (2.a).

   (2.i)  If the document underwent an IETF Last Call and the AD
          concludes that significant issues were raised during the Last
          Call, then steps (2.b) through (2.h) need to be applied
          addressing the Last Call issues.  This requires the
          Responsible Area Director to present to the Document Shepherd
          those Last Call issues raised only to the IESG.

3.3.  Document Shepherding during IESG Evaluation

   During IESG Evaluation of a document, ADs can bring forward two kinds
   of remarks about a document: DISCUSS items and COMMENT items.  A
   DISCUSS blocks a document's approval process until it has been
   resolved; a COMMENT does not.  This section details the steps that a
   Document Shepherd takes to resolve any DISCUSS and COMMENT items
   brought forward against a shepherded document during IESG Evaluation.

   Note that DISCUSS and COMMENT items are occasionally written in a
   manner that makes their intent unclear.  In these cases, the Document
   Shepherd SHOULD start a discussion with the ADs who brought the items
   up to clarify their intent, keeping the Responsible Area Director
   informed.  If this fails to clarify the intent, the Responsible Area
   Director may need to work towards a clarification inside the IESG.

   (3.a)  Leading up to the IESG conference call, the Document Shepherd
          may see emails about the document from directorate reviewers
          on behalf of one or more ADs and also emailed copies of
          DISCUSS and COMMENT items entered into the ID Tracker.  The
          Document Shepherd SHOULD immediately begin to work on
          resolving DISCUSS and COMMENT items with the ADs who have
          raised them, keeping the Responsible Area Director copied on

          the email exchange, so that he or she is able to support the
          activity during the conference call.  When dealing with
          directorate reviews, the Document Shepherd MUST involve the
          ADs to whom these directorates report to ensure that these ADs
          consider the review comments that need resolving.

   (3.b)  Immediately following the conference call, when the document
          changes state from the "IESG Evaluation" state to one of the
          states requiring Document Shepherd action, e.g., "IESG
          Evaluation: Revised ID Needed" or "IESG Evaluation: AD
          Followup", the Document Shepherd will receive email.  A state
          of "AD Followup" typically signifies the Responsible Area
          Director's hope that a resolution may be possible through a
          continued discussion or (more usually) through a small set of
          changes as "Notes to the RFC Editor".

          Note that there may be very exceptional cases when DISCUSS
          items are registered after an IESG conference call.  In these
          cases, the AD who has raised the DISCUSS MUST notify the
          Document Shepherd about it.  (The notification facility in the
          ID Tracker is very convenient for this purpose and also for
          the cases where the DISCUSS and COMMENT items are updated
          after they are partially resolved.)

   (3.c)  The Document Shepherd then queries the ID Tracker to collect
          the remaining DISCUSS and COMMENT items raised against the
          document.  The Document Shepherd analyzes these items and
          initializes contact with the ADs who have placed them.  The
          Responsible Area Director MUST be copied on all correspondence
          related to active DISCUSS or COMMENT items.  This does not
          place the Responsible Area Director in the critical path
          towards a resolution, but should keep him or her informed
          about the state of the discussion.

   (3.d)  The Document Shepherd then coordinates the resolution of
          DISCUSS and COMMENT items and builds a consistent
          interpretation of the comments.  This step is similar to much
          of the process described in Section 3.2.

              +--------------------------+

   (3.e)  The Document Shepherd then communicates the DISCUSS and
          COMMENT items to the document editors and the working group,
          alerting them of any changes to the document that have
          accumulated during IESG processing, such as "Notes to the RFC
          Editor".  If any changes will be substantive, the Document
          Shepherd, in consultation with the Responsible Area Director,
          as during other stages, MUST confirm working group consensus
          or sometimes even IETF consensus.

   (3.f)  After the editors resolve the DISCUSS and COMMENT items, the
          Document Shepherd reviews the resulting new version of the
          document, which will be a revised document, a set of "Notes to
          the RFC Editor", or both, using his or her technical expertise
          to ensure that all raised DISCUSS and COMMENT issues have been
          resolved.

          Note that the Document Shepherd MAY also suggest resolutions
          to DISCUSS and COMMENT items, enter them into an issue
          tracker, or perform other steps to streamline the resolution
          of the evaluation comments.  It is very important to resolve
          the comments in a timely way, while the discussion is current
          for everyone involved.

   (3.g)  When the Document Shepherd is satisfied that the revised
          document addresses the evaluation comments, he or she
          communicates the resolution to the Responsible Area Director
          and the ADs that had raised the DISCUSS and COMMENT items.

   (3.h)  Each AD who had raised a DISCUSS checks whether the
          communicated resolution addresses his or her items.  If it
          does, the AD will clear the DISCUSS.  If it does not, the AD
          notifies the Document Shepherd and adds information to the ID
          Tracker explaining why the DISCUSS was not resolved.  The
          Document Shepherd informs the working group accordingly.
          (COMMENT items need not be checked and cleared, because they
          do not block the document, but ADs are encouraged to do so.)

          If a DISCUSS was not resolved to the satisfaction of the AD
          that has raised it or the Responsible Area Director, two
          possibilities exist:



Levkowetz, et al.            Informational                     [Page 12]
^L
RFC 4858          Document Shepherding to Publication           May 2007


          (a)  The process returns to step (3.d), or

          (b)  If no progress can be made on the resolution of the
               DISCUSS with the AD who has raised it, despite repeated
               clarifications and discussions, the Responsible Area
               Director should take over continued shepherding of the
               document.  Such a situation may be indicative of larger
               issues that the PROTO process was not designed to handle.

          Once the process above has cleared all DISCUSS items, document
          shepherding continues with step (3.i).

   (3.i)  The Responsible Area Director moves the document to the
          "Approved - Announcement to be sent" state in the ID Tracker.
          If he or she deems the changes to the revised document
          significant, there may be a new WG Last Call, or possibly a
          new IETF Last Call.  The document goes through a new full IESG
          Evaluation process if there is a new IETF Last Call.

4.  Shepherding the Document's IANA Actions

   IETF working group documents often include considerations requiring
   actions by the IANA, such as creating a new registry or adding
   information to an existing registry, perhaps after consulting an
   IESG-appointed Expert.  Sometimes the Document Shepherd must keep
   track of certain IANA actions to be completed by the IESG, such as
   ratifying the appointment of a designated Expert called for in the
   IANA Considerations.  IANA-related processing may also include a
   specified type of Expert review, such as review of proposed MIME
   media types on the designated ietf-types mailing list.

   The IANA reviews IETF documents and requests responses at any or all
   of the following times: in response to IETF Last Call, during the
   IESG Evaluation review of the document, and at the time when the IANA
   performs actions in its web-based registry for the document, usually
   but not always after IESG approval of the document.  More details of
   the IANA process and IETF interaction are found in [RFC2434].

   At the time of this publication, RFC 2434 is under revision
   [RFC2434bis], and the updates are and will be of value to the
   Document Shepherd.  Note that the Document Shepherd MUST determine
   (by individual review and consultation with others) what is the most
   recent and the most applicable IANA information and guidance for his
   or her document, be it the overall guidance, or external documents in
   his or her area, or in other areas.  An example of an external
   document is [RFC4020].





Levkowetz, et al.            Informational                     [Page 13]
^L
RFC 4858          Document Shepherding to Publication           May 2007


   Whenever an IANA request comes, during whatever phase of the
   shepherding process, the requester from IANA MUST ensure that the
   Document Shepherd and the Responsible Area Director both receive the
   request.  The Document Shepherd is responsible for responding as
   rapidly as possible.  He or she should discuss requests that
   introduce any possible concerns with the working group.  The Document
   Shepherd and the Responsible Area Director may decide in consultation
   that an IANA request leads to a change that needs additional review
   or approval.

   In general, the Document Shepherd ensures that the IANA process
   completes, checks that the registry is correct and that the IANA
   Matrix (http://www.iana.org/numbers.html) is complete and consistent,
   and troubleshoots when all is not well.  At the end of IANA
   processing, the Document Shepherd should be sure that the RFC Editor
   has acknowledged IANA conclusion, i.e., that the handoff has been
   made.

   In summary, the task of shepherding the IANA actions is often
   overlooked, but is as important to coordinate and manage as all the
   other document reviews the Document Shepherd has managed.  As with
   those, the Document Shepherd contributes greatly to quality and
   timeliness of the document by effective and responsive shepherding of
   the IANA requests.

5.  Document Shepherding after IESG Approval

   After the IESG Evaluation and resolution described in Section 3.3,
   the IESG approves the document, and the Responsible Area Director
   uses the ID Tracker to ask for any final changes to the Document
   Announcement Write-Up and for it to be issued.  The Document Shepherd
   may have some edits for the Responsible Area Director, such as minor
   "Notes to the RFC Editor", and this is the time to consult and
   provide them.

   The IESG approval announcement goes to the general community and to
   the RFC Editor, and now the Document Shepherd (identified in the
   Announcement Write-Up) continues to shepherd the document through its
   technical publication.  The RFC Editor currently makes a number of
   types of requests to the authors, Document Shepherd and Responsible
   Area Director.  The Document Shepherd SHOULD lead in responding to
   the RFC Editor and shepherd the document during the post-approval
   period to its publication.

   The RFC Editor request types include: editorial queries about
   dangling or missing informative and normative citations (good
   shepherding should try to catch these earlier, but they happen);
   requests for the document source (e.g., XML or nroff); occasional



Levkowetz, et al.            Informational                     [Page 14]
^L
RFC 4858          Document Shepherding to Publication           May 2007


   technical comments; and copy-edits for review and close scrutiny by
   the authors (AUTH48).  For the latter, the Document Shepherd SHOULD
   lead in checking that copy-edits have in no case affected a consensus
   wording of the working group that prepared the document, and SHOULD
   bring speed to this checking by multiple coauthors.  The Document
   Shepherd also consults with the Responsible Area Director on
   reviewing proposed post-approval changes to the document by any
   author.  These may require Area Director approval, and they often
   need to be presented to the working group for consent if not a full
   consensus procedure.

   As in other phases of document shepherding, the Document Shepherd
   provides attentiveness and timeliness by serving as the informed
   representative of the document and helping its advancement and its
   integrity.

6.  When Not to Use the Document Shepherding Process

   As mentioned in Section 3, the Document Shepherd SHOULD NOT be an
   editor of the shepherded document.  If this cannot be avoided by
   making another working group chair or secretary the Document
   Shepherd, the document shepherding process SHOULD NOT be used.  There
   are several other cases in which the document shepherding process
   SHOULD NOT be used.  These include:

   1.  Cases where the Document Shepherd is the primary author or editor
       of a large percentage of the documents produced by the working
       group.

   2.  Cases where the Responsible Area Director expects communication
       difficulties with the Document Shepherd (either due to
       experience, strong views stated by the Document Shepherd, or
       other issues).

   3.  Cases where the working group itself is either very old, losing
       energy, or winding down (i.e., cases where it would not be
       productive to initiate new processes or procedures).

   Finally, note that other cases exist in which using the document
   shepherding process may not be productive.  The final determination
   as to whether or not to use the document shepherding process is left
   to the Responsible Area Director.  If the document shepherding
   process is not used, the Responsible Area Director acts as Document
   Shepherd, per the existing procedures of shepherding by Area
   Directors.

Appendix A.  Example Document Announcement Write-Ups

   This appendix includes two examples of Document Announcement Write-
   Ups.  Many more examples with Subject lines such as "Protocol Action"
   and "Document Action" can be found in the IETF-announce mailing list
   archive.

A.1.  Example Document Announcement Write-Up for
      draft-ietf-avt-rtp-midi-format

   Technical Summary

      These documents define the RTP Payload format for MIDI (Musical
      Instrument Digital Interface), and additional guidelines on
      implementation specifically concerning the timing of reception and
      transmission for best performance in different applications.  MIDI
      is a real-time media, which however is brittle to losses and
      errors.  Therefore the RTP payload format defines recovery
      journals as a way of avoiding persistent audible errors, and
      discusses congestion control handling for these journals.

      The RTP payload for MIDI encodes the broad range of MIDI commands.
      The format is suitable for interactive applications (such as
      network musical performance) and content-delivery (such as file
      streaming).

   Working Group Summary

      There is consensus in the WG to publish these documents.

   Document Quality

      This RTP Payload format has been implemented during the
      development of the specification and successfully tested over an
      IP network between two remote sites, thus showing that the
      technical solution is successfully working.  It has been reviewed
      by the MIDI Manufacturers Association and their comments have been
      addressed.

   Personnel

      Magnus Westerlund and Colin Perkins jointly shepherded this
      document.  Allison Mankin reviewed the document for the IESG,
      including a careful review with the editor of the media types, in
      parallel with ietf-types list review requested on 2006-01-08,
      which raised no issues.

A.2.  Example Document Announcement Write-Up for
      draft-ietf-imss-ip-over-fibre-channel

   Technical Summary

      This document specifies the encapsulation of IPv6, IPv4 and ARP
      packets over Fibre Channel.  This document also specifies the
      methods for forming IPv6 link-local addresses and statelessly
      autoconfigured IPv6 addresses on Fibre Channel networks, and a
      mechanism to perform IPv4 address resolution over Fibre Channel
      networks.  This document (when published as RFC) obsoletes RFC2625
      and RFC3831.

   Working Group Summary

      This document has been reviewed by Fibre Channel experts in
      Technical Committee T11 (Fibre Channel standards organization) in
      addition to members of the IMSS WG.  There is solid support for
      this document both in the WG and from T11.

   Document Quality

      This document replaces and consolidates two separate RFCs on IPv4
      over Fibre Channel (RFC 2625) and IPv6 over Fibre Channel (RFC
      3831).  Most of its technical content is unchanged from those
      RFCs.  The technical changes that have been made are primarily
      based on implementation experience.

   Personnel

      The protocol has been reviewed for the IESG by David L. Black (WG
      chair).  Bert Wijnen has reviewed this document for the IESG.  In
      addition, Brian Haberman has done a review for the INT Area as
      requested by WG-chair (David Black) via Margaret Wasserman.
