Shepherd writeup

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?

Informational looks appropriate for registering new LDAP attributes and object classes to be used for storing XMPP JIDs. The registry is "Expert Review", but having an RFC would improve 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

   The Extensible Messaging and Presence Protocol (XMPP) identifies
   users by use of JID (Jabber IDs).  Lightweight Directory Access
   Protocol (LDAP) enables provision of a white pages service with
   schema relating to users and support for internet protocols.  This
   specification defines schema to enable XMPP JIDs to be associated
   with objects in an LDAP directory so that this information can be
   used with white pages applications.

Working Group Summary

   This document was not considered by any WG, as there are no active
   LDAP or XMPP WGs at the moment. However it was reviewed by
   both LDAP and XMPP experts.

Document Quality

   NATO and UK MoD representatives expressed interest in using
   the schema. As no new LDAP attribute syntaxes are proposed,
   adding this to schema of existing LDAP servers is easy,
   as it just requires adding corresponding OID and attribute syntax name
   to schema files.

   The document was also reviewed by LDAP (e.g. Kurt Zeilenga)
   and XMPP experts (e.g. Peter Saint-Andre).

   The document was improved in response to IANA questions and comments from NATO.


   Alexey Melnikov is the document shepherd. Ben Campbell is the responsible AD.

(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.

   I verified references and checked LDAP schema against LDAP IANA registries.
   I also checked ID-nits.

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


(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 interested community has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here.

   I raised the issue of differences in matching rules between LDAP and XMPP. The new text in the latest version
   addressed my concerns to my satisfaction.

(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. There are no IPR on this document.

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


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

   There is sufficient support for this proposal from both LDAP and XMPP experts.

(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 thorough.

   None found.

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

   IANA has requested LDAP Expert review for this document. I believe the review has been completed and comments from Designated Expert were responded to.

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

   Yes. All references in the document are Normative.

(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?

   All normative references point to existing RFCs.

(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 interested community considers it unnecessary.

   This document doesn't affect existing RFCs.

(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).

   IANA registration section requests registration of 1 new object class and 1 new attribute. IANA is requested to assign an OID, that will be used as a prefix for both of these registrations.

(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 created by this document.

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

   The document doesn't include ABNF, XML or MIBs.
