Introduction BCP 9 [RFC2026] has been the basis for the IETF standards process for many years. RFC 2026 has been in force since 1996, and has proved robust and adequately flexible for the main part. However, some provisions have led to practical difficulties or lack clarity. The changes defined here are intended to tackle those issues. This document is organized as follows. Firstly, there is an overview of the changes. Then, the substantive changes are listed and explained in textual sequence, illustrated with extracts from RFC 2026. Even single-word changes are listed if they are considered substantive. Then, the mandatory sections of any RFC are included. Finally, an Appendix lists purely editorial changes in RFC 2026. 2. Overview of Changes This section summarizes the changes made to RFC 2026. Additional explanation is included below, among the details of the changes. o Rationalize the way in which standards are referenced and numbered, by: 1. Assigning acronyms and numbers to standards at each stage of the standards track, not just at the final stage; 2. Clarifying in all indexes that more recent standards obsolete older ones regardless of their respective stages on the standards track; 3. Formally abolishing the "STD 1" RFCs. o Tidy up terminology and explanatory text in the standards track definition. The changes are based on the existing three stage standards track, with goal of adjusting the rules to make it fully workable. o Place responsibility for initiating the advancement or deprecation of stalled documents back in the community rather than expecting the IESG to do it. o Formalize the reality that non-Working Group documents of any kind may be processed by the IETF and approved by the IESG. o Clarify the description of Applicability Statements. o Collate in one place the principles about normative references. o Give the IESG explicit authority to define the granularity of interoperability testing. o Simplify the variance process. o Clarify that the appeals process applies to all decisions. Additionally, there are several smaller changes that are intended only for clarification and alignment with reality. An Appendix lists purely editorial changes. Carpenter Expires July 19, 2008 [Page 3] Internet-Draft RFC 2026 Changes January 2008 3. Detailed Changes Extracts from RFC 2026 are presented verbatim in quotation marks, preceded and followed by these markers: "---------Begin Extract--------- -----------End Extract---------" Proposed changes are presented as plain text. 3.1. Change to Section 1.1 Internet Standards "---------Begin Extract--------- The Internet Standards Process described in this document is concerned with all protocols, procedures, and conventions that are used in or by the Internet, whether or not they are part of the TCP/IP protocol suite. In the case of protocols developed and/or standardized by non-Internet organizations, however, the Internet Standards Process normally applies to the application of the protocol or procedure in the Internet context, not to the specification of the protocol itself. -----------End Extract---------" CHANGE: Replace the last sentence by: In the case of protocols developed and/or standardized outside the IETF, the Internet Standards Process may be applied to the use of the protocol in the Internet context. Similarly, IETF protocols may be cited in specifications developed elsewhere. The IETF will not normally modify protocols developed elsewhere, and does not normally permit its protocols to be modified elsewhere. RATIONALE: The previous text did not allow for the complexity of interaction between IETF and non-IETF protocols, nor set the proper context for liaison relationships. 3.2. Changes to Section 2.1 Requests for Comments (RFCs) "---------Begin Extract--------- The status of Internet protocol and service specifications is summarized periodically in an RFC entitled "Internet Official Protocol Standards" [1]. This RFC shows the level of maturity and other helpful information for each Internet protocol or service specification (see section 3). -----------End Extract---------" Carpenter Expires July 19, 2008 [Page 4] Internet-Draft RFC 2026 Changes January 2008 CHANGE: Delete this paragraph and all other references to STD1. RATIONALE: This was written before a hyperlinked index was available on line. "---------Begin Extract--------- Some RFCs document Internet Standards. These RFCs form the 'STD' subseries of the RFC series [4]. When a specification has been adopted as an Internet Standard, it is given the additional label "STDxxx", but it keeps its RFC number and its place in the RFC series. (see section 4.1.3) -----------End Extract---------" CHANGE: Replace the last sentence by: When a specification has been approved for publication on the standards track, it is assigned a Standard Number (e.g. 10) and a Standard Acronym (e.g. SMTP), independent of its RFC number and its place in the RFC series. As a specification changes status within the standards track, its Standard Number remains the same, and is associated with the most recent version of the specification, regardless of its maturity level. Historically, RFCs that document Internet Standards formed the 'STD' subseries of the RFC series [4]. Acronyms may comprise sub-acronyms (e.g. SMTP/Submission) in the case of multipart standards. RATIONALE: The fact that only full Standards receive an STD number, and possibly an acronym, is today a major source of confusion to users of the standards, since these numbers and acronyms are not associatd with PS and DS documents. Users do not, in fact, know where to look for the latest standard, since a DS may obsolete an STD, and a PS may obsolete either. It would be much less confusing if a new or existing acronym was assigned as part of the initial standards action (thus RFC 2821 would have been associated with SMTP). Similarly, the STD number should be assigned at PS stage for simpler tracking - thus RFC 2821 would also be known as PS10, replacing the older RFC 821 previously known as STD10. (Also see comments on section 4.1.3.) "---------Begin Extract--------- Carpenter Expires July 19, 2008 [Page 5] Internet-Draft RFC 2026 Changes January 2008 Not all specifications of protocols or services for the Internet should or will become Internet Standards or BCPs. Such non-standards track specifications are not subject to the rules for Internet standardization. Non-standards track specifications may be published directly as "Experimental" or "Informational" RFCs at the discretion of the RFC Editor in consultation with the IESG (see section 4.2). -----------End Extract---------" CHANGE: Replace this paragraph by: Not all specifications of protocols or services for the Internet should or will become Internet Standards or BCPs. The various paths to publication are defined in [RFC4844]. Non-standards track IETF specifications may be published as "Experimental" or "Informational" RFCs if approved by the IESG. When non-standards track specifications are produced within the IETF, they are subject to the rules of the IETF except those specific to Section 5 and Sections 6.1 through 6.4 of [RFC2026]. RATIONALE: IETF Experimental or Informational RFCs are distinct from independent submissions to the RFC Editor, which are now processed under [RFC4846] and [RFC3932], and from IAB [RFC4845] and IRTF documents. Also, we want all IETF documents to be subject to many of our rules, such as the IPR rules and the appeals process. 3.3. Changes to Section 2.2 Internet-Drafts "---------Begin Extract--------- During the development of a specification, draft versions of the document are made available for informal review and comment by placing them in the IETF's "Internet-Drafts" directory, which is replicated on a number of Internet hosts. This makes an evolving working document readily available to a wide audience, facilitating the process of review and revision. An Internet-Draft that is published as an RFC, or that has remained unchanged in the Internet-Drafts directory for more than six months without being recommended by the IESG for publication as an RFC, is simply removed from the Internet-Drafts directory. -----------End Extract---------" CHANGE: Replace 'recommended' by 'considered'. RATIONALE: Expiry is inhibited when a draft enters IESG consideration, not when it is approved. Carpenter Expires July 19, 2008 [Page 6] Internet-Draft RFC 2026 Changes January 2008 CHANGE: Add the following two paragraphs: Internet-Drafts are also removed from the directory after publication as an RFC. However, all versions of all Internet-Drafts are retained in the IETF archive for legal reasons and may be subject to subpoena. Authors should be aware that expired Internet-Drafts are unofficially available in many places. Authors may request expired Internet- Drafts to be removed from such availability, but this is outside the control of the IETF. The published RFC will not be textually identical to the final version of the Internet-Draft. Not only will the required boilerplate text be finalized; the RFC Editor will also make editorial corrections, and apply minor technical changes approved by the sponsoring Area Director or the IESG. RATIONALE: Aligning with reality. 3.4. Changes to Section 3.1 Technical Specification (TS) "---------Begin Extract--------- A Technical Specification is any description of a protocol, service, procedure, convention, or format. -----------End Extract---------" CHANGE: Add the following paragraph: Thus a TS is not limited to defining a protocol; it may for example define an Application Programming Interface (i.e. a convention) or a data definition such as a MIB or an IANA registry (i.e. a format). However, a TS must be both implementable and testable. RATIONALE: Although clearly within the intended scope of RFC 2026, these types of TS have been a source of debate and deserve clarification. Also see later comments on implementation reports. "---------Begin Extract--------- A TS shall include a statement of its scope and the general intent for its use (domain of applicability). Thus, a TS that is inherently specific to a particular context shall contain a statement to that effect. However, a TS does not specify requirements for its use within the Internet; these requirements, which depend on the particular context in which the TS is incorporated by different system configurations, are defined by an Applicability Statement. Carpenter Expires July 19, 2008 [Page 7] Internet-Draft RFC 2026 Changes January 2008 -----------End Extract---------" CHANGE: Delete the 3rd sentence. RATIONALE: The last sentence very unclear. Is it saying that a TS doesn't contain operational guidelines? Quite often, the Operations Area comments on a draft TS are, in effect, asking for operational guidelines. If a TS refers to a timeout or some other behavioural parameter, Operations people may insist on specifying a default value and guidance about when to change the default. But the above sentence could suggest that this belongs in a separate AS. In practice, few authors separate such things from the basic specification. The simplest resolution is to drop the whole sentence. 3.5. Changes to Section 3.2 Applicability Statement (AS) "---------Begin Extract--------- An Applicability Statement specifies how, and under what circumstances, one or more TSs may be applied to support a particular Internet capability. An AS may specify uses for TSs that are not Internet Standards, as discussed in Section 7. -----------End Extract---------" CHANGE: Insert the following after this paragraph: The following description refers to an AS as if it were a separate document. In practice, the applicability information is commonly embedded in the relevant TS. RATIONALE: The community really doesn't have the habit of writing separate AS documents; it's rare, and very rare in WG charters. Such a document has more significance than an Informational document, but can only be placed on the standards track along with relevant TSs, because it can't be implemented and tested in itself. "---------Begin Extract--------- The broadest type of AS is a comprehensive conformance specification, commonly called a "requirements document", for a particular class of Internet systems, such as Internet routers or Internet hosts. -----------End Extract---------" CHANGE: Delete this paragraph. Carpenter Expires July 19, 2008 [Page 8] Internet-Draft RFC 2026 Changes January 2008 RATIONALE: Firstly, this is not the community's normal understanding of a conformance specification, which generally refers to product certification. Secondly, in the IETF today, we use the word "requirements" much more broadly, typically for an Informational document describing the problem to be solved by one or more TS documents. "---------Begin Extract--------- An AS may not have a higher maturity level in the standards track than any standards-track TS on which the AS relies (see section 4.1). For example, a TS at Draft Standard level may be referenced by an AS at the Proposed Standard or Draft Standard level, but not by an AS at the Standard level. -----------End Extract---------" CHANGE: Move this paragraph to a new general section on normative reference requirements, and rewrite as: A standards-track document should not have a higher maturity level in the standards track than any standards-track document on which it relies normatively. RATIONALE: There is nothing specific to ASes in this rule; it is applied globally wherever normative references occur. See comment below on 4.2.4. 3.6. Changes to Section 3.3 Requirement Levels "---------Begin Extract--------- An AS shall apply one of the following "requirement levels" to each of the TSs to which it refers: -----------End Extract---------" CHANGE: Replace by: A specification or BCP shall apply one of the following "requirement levels" to each specification or BCP to which it refers: CHANGE: Throughout the following clauses (a) through (e), read "referenced specification or BCP" for each occurrence of "referenced TS", and "referring specification or BCP" for each occurrence of "AS". RATIONALE: There is nothing specific to AS vs TS vs BCP in these Carpenter Expires July 19, 2008 [Page 9] Internet-Draft RFC 2026 Changes January 2008 requirement levels. "---------Begin Extract--------- The "Official Protocol Standards" RFC (STD1) lists a general requirement level for each TS, using the nomenclature defined in this section. This RFC is updated periodically. In many cases, more detailed descriptions of the requirement levels of particular protocols and of individual features of the protocols will be found in appropriate ASs. -----------End Extract---------" CHANGE: Replace the first two sentences by: The RFC Editor web site displays the current maturity level of each standards track document, as well as the status of all RFCs. RATIONALE: Aligning with reality. 3.7. Changes to Section 4.1.1 Proposed Standard "---------Begin Extract--------- Implementors should treat Proposed Standards as immature specifications. It is desirable to implement them in order to gain experience and to validate, test, and clarify the specification. However, since the content of Proposed Standards may be changed if problems are found or better solutions are identified, deploying implementations of such standards into a disruption-sensitive environment is not recommended. -----------End Extract---------" CHANGES: 1. Rename PS as Preliminary Standard. 2. Add the following text: Preliminary Standard is indeed the preliminary level. Implementors should be aware that a PS may be revised or even withdrawn. However, it is nevertheless common to use PS implementations operationally. Many documents spend their entire active life as PS. Certain types of specification, e.g. data formats such as MIBs, are likely to be recycled at PS as they evolve rather than being promoted. This may be a result of complexity, or due to intrinsic difficulties in interoperability testing and normative dependencies. Carpenter Expires July 19, 2008 [Page 10] Internet-Draft RFC 2026 Changes January 2008 RATIONALE: It is well known that to a large extent the warnings about PS have been ignored, and that the Internet "runs on Proposed Standards." Also, as the MIB doctors have observed, some types of specification may benefit from being recycled at this level rather than being "promoted." The name change makes the status more immediately obvious. 3.8. Changes to Section 4.1.2 Draft Standard CHANGE: Rename as Deployable Standard. RATIONALE: Just as "proposed" standard is effectively interpreted as "preliminary", "draft standard" is effectively interpreted as much more than a draft. Also we have the problem of confusion with "Internet-Draft." The name change reduces this risk of confusion and clarifies the factual status. "---------Begin Extract--------- A specification from which at least two independent and interoperable implementations from different code bases have been developed, and for which sufficient successful operational experience has been obtained, may be elevated to the "Draft Standard" level. For the purposes of this section, "interoperable" means to be functionally equivalent or interchangeable components of the system or process in which they are used. If patented or otherwise controlled technology is required for implementation, the separate implementations must also have resulted from separate exercise of the licensing process. Elevation to Draft Standard is a major advance in status, indicating a strong belief that the specification is mature and will be useful. The requirement for at least two independent and interoperable implementations applies to all of the options and features of the specification. -----------End Extract---------" CHANGE: Add the following paragraph: The IESG is empowered (subject to community consensus) to define the level of granularity required in interpreting this requirement, and how to demonstrate interoperability for specifications that do not define protocols or have a single-ended nature. RATIONALE: At least the four significant questions below arise repeatedly in interpreting this rule. It seems best to leave this to the IESG and its assessment of community consensus, rather than to set rigid rules. Carpenter Expires July 19, 2008 [Page 11] Internet-Draft RFC 2026 Changes January 2008 1. What is a "feature"? This can be interpreted in many ways. For a TLV field is every separate type code a feature? Is every use of a normative keyword [RFC2119] a feature? 2. Is it acceptable if features A and B are shown to be interoperable between implementations X and Y, and features C and D are shown to be interoperable between implentations P and Q? In that case we have shown interoperability of features A, B, C and D but have not shown that any implementation successfully interoperates with all of them. Since the goal is to use running code to verify that the specification in question enables interoperability, not to test whether the implementations comply, the answer appears to be yes. Also note that as far as validating the specification is concerned, all features must be tested, regardless of whether they are optional, recommended or mandatory to implement or to use. 3. Is it acceptable if both implementations X and Y show interoperability with implementation Q, but the implementor of Q is not party to the tests and does not make any statements about features supported? In other words Q has merely served as an active mirror in the tests. 4. How should we handle the issue of "single-ended" technical specifications such as data formats, where there is no new protocol whose interoperation we can verify? A practical solution for MIBs has been documented [RFC2438] and some generalisation of this seems to be needed. "---------Begin Extract--------- In cases in which one or more options or features have not been demonstrated in at least two interoperable implementations, the specification may advance to the Draft Standard level only if those options or features are removed. The Working Group chair is responsible for documenting the specific implementations which qualify the specification for Draft or Internet Standard status along with documentation about testing of the interoperation of these implementations. The documentation must include information about the support of each of the individual options and features. This documentation should be submitted to the Area Director with the protocol action request. (see Section 6) -----------End Extract---------" CHANGE: Add this sentence: The Area Director and the IESG must be satisfied that the the level Carpenter Expires July 19, 2008 [Page 12] Internet-Draft RFC 2026 Changes January 2008 of detail in such implementation reports is sufficient to satisfy the interoperation requirements. RATIONALE: Examining the database of reports collected over the years at , the quality is highly variable and some are very sparse and uninformative. 3.9. Changes to Section 4.1.3 Internet Standard "---------Begin Extract--------- A specification that reaches the status of Standard is assigned a number in the STD series while retaining its RFC number. -----------End Extract---------" CHANGE: Replace by: A specification that reaches the status of Standard is assigned the same Standard number as its predecessors at PS and DS status, as well as an RFC number. RATIONALE: see above re section 2.1. 3.10. Changes to Section 4.2.2 Informational "---------Begin Extract--------- An "Informational" specification is published for the general information of the Internet community, and does not represent an Internet community consensus or recommendation. The Informational designation is intended to provide for the timely publication of a very broad range of responsible informational documents from many sources, subject only to editorial considerations and to verification that there has been adequate coordination with the standards process (see section 4.2.3). -----------End Extract---------" CHANGE: Add: In practice, some Informational and Experimental RFCs that are published following IESG Approval are very close to being a TS or AS and are evaluated almost as carefully. Others are more general. RATIONALE: Aligning with reality. In particular, requirements documents that will guide future work deserve more careful review by the IESG than other Informational RFCs. Carpenter Expires July 19, 2008 [Page 13] Internet-Draft RFC 2026 Changes January 2008 "---------Begin Extract--------- Specifications that have been prepared outside of the Internet community and are not incorporated into the Internet Standards Process by any of the provisions of section 10 may be published as Informational RFCs, with the permission of the owner and the concurrence of the RFC Editor. -----------End Extract---------" CHANGE: Replace by: As mentioned above, some RFCs are published outside the IETF process; see [RFC4844] and [RFC4846]. RATIONALE: Should not duplicate this material, to avoid inconsistency. 3.11. Changes to Section 4.2.3 Procedures for Experimental and Informational RFCs "---------Begin Extract--------- Unless they are the result of IETF Working Group action, documents intended to be published with Experimental or Informational status should be submitted directly to the RFC Editor. -----------End Extract---------" CHANGE: Replace by: Documents intended to be published with Experimental or Informational status via the IETF process, that are not the result of IETF Working Group action, must be sponsored by an Area Director, in the same way as a standards track or BCP document that is not the result of IETF Working Group action, using procedures defined by the IESG. Documents intended to be published independently of the IETF with Experimental or Informational status should be submitted directly to the RFC Editor. RATIONALE: Aligning with reality. "---------Begin Extract--------- Carpenter Expires July 19, 2008 [Page 14] Internet-Draft RFC 2026 Changes January 2008 The RFC Editor will publish any such documents as Internet-Drafts which have not already been so published. In order to differentiate these Internet-Drafts they will be labeled or grouped in the I-D directory so they are easily recognizable. The RFC Editor will wait two weeks after this publication for comments before proceeding further. The RFC Editor is expected to exercise his or her judgment concerning the editorial suitability of a document for publication with Experimental or Informational status, and may refuse to publish a document which, in the expert opinion of the RFC Editor, is unrelated to Internet activity or falls below the technical and/or editorial standard for RFCs. -----------End Extract---------" CHANGE: Replace by: The RFC Editor will publish any such documents in accordance with [RFC4846]. RATIONALE: Should not duplicate this material, to avoid inconsistency. "---------Begin Extract--------- To ensure that the non-standards track Experimental and Informational designations are not misused to circumvent the Internet Standards Process, the IESG and the RFC Editor have agreed that the RFC Editor will refer to the IESG any document submitted for Experimental or Informational publication which, in the opinion of the RFC Editor, may be related to work being done, or expected to be done, within the IETF community. The IESG shall review such a referred document within a reasonable period of time, and recommend either that it be published as originally submitted or referred to the IETF as a contribution to the Internet Standards Process. -----------End Extract---------" CHANGE: Replace by: To ensure that the independent submissions track is not misused to circumvent the Internet Standards Process, the IESG, the IAB and the RFC Editor have agreed that the RFC Editor will refer to the IESG any document submitted for Experimental or Informational publication which, in the opinion of the RFC Editor, may be related to work being done, or expected to be done, within the IETF community. The IESG shall review such a referred document within a reasonable period of time, and recommend a course of action to the RFC Editor [RFC4846], Carpenter Expires July 19, 2008 [Page 15] Internet-Draft RFC 2026 Changes January 2008 [RFC3932]. RATIONALE: Aligning with reality. 3.12. Changes to Section 4.2.4 Historic "---------Begin Extract--------- A specification that has been superseded by a more recent specification or is for any other reason considered to be obsolete is assigned to the "Historic" level. (Purists have suggested that the word should be "Historical"; however, at this point the use of "Historic" is historical.) -----------End Extract---------" CHANGE: Replace this paragraph by: A specification that has been superseded by a more recent specification or is for any other reason considered to be obsolete may be assigned to the "Historic" level by the IESG. (Purists have suggested that the word should be "Historical"; however, at this point the use of "Historic" is historical.) RATIONALE: Aligning with reality. "---------Begin Extract--------- Note: Standards track specifications normally must not depend on other standards track specifications which are at a lower maturity level or on non standards track specifications other than referenced specifications from other standards bodies. (See Section 7.) -----------End Extract---------" CHANGE: move this paragraph to the new section proposed in the comments on section 3.2. Also add there: Standards track and BCP documents must, and other documents should, distinguish between normative and informative references. Normative references are those that are required reading to correctly understand and implement a specification. Procedures exist to allow normative references to less mature documents [RFC3967], [RFC4897]. RATIONALE: we need to clarify and collate the rules about normative references. Carpenter Expires July 19, 2008 [Page 16] Internet-Draft RFC 2026 Changes January 2008 3.13. Change to Section 5. BEST CURRENT PRACTICE (BCP) RFCs "---------Begin Extract--------- While it is recognized that entities such as the IAB and IESG are composed of individuals who may participate, as individuals, in the technical work of the IETF, it is also recognized that the entities themselves have an existence as leaders in the community. As leaders in the Internet technical community, these entities should have an outlet to propose ideas to stimulate work in a particular area, to raise the community's sensitivity to a certain issue, to make a statement of architectural principle, or to communicate their thoughts on other matters. The BCP subseries creates a smoothly structured way for these management entities to insert proposals into the consensus-building machinery of the IETF while gauging the community's view of that issue. -----------End Extract---------" CHANGE: Add: Such BCPs are subject to the normal process of IETF review and IESG approval. RATIONALE: Important clarification. 3.14. Change to Section 6.1.1 Initiation of Action "---------Begin Extract--------- A specification that is intended to enter or advance in the Internet standards track shall first be posted as an Internet-Draft (see section 2.2) unless it has not changed since publication as an RFC. It shall remain as an Internet-Draft for a period of time, not less than two weeks, that permits useful community review, after which a recommendation for action may be initiated. A standards action is initiated by a recommendation by the IETF Working group responsible for a specification to its Area Director, copied to the IETF Secretariat or, in the case of a specification not associated with a Working Group, a recommendation by an individual to the IESG. -----------End Extract---------" CHANGE: Replace second paragraph by: A standards action is initiated by a recommendation by the IETF Carpenter Expires July 19, 2008 [Page 17] Internet-Draft RFC 2026 Changes January 2008 Working group responsible for a specification to an Area Director, copied to the IETF Secretariat or, in the case of a specification not associated with a Working Group, an agreement by an Area Director to recommend a specification to the IESG. The IESG defines the procedures for this. An Area Director will normally be recused from sponsoring a document to which he or she has made a substantial contribution. RATIONALE: Aligning with reality. 3.15. Changes to Section 6.1.3 Publication "---------Begin Extract--------- An official summary of standards actions completed and pending shall appear in each issue of the Internet Society's newsletter. This shall constitute the "publication of record" for Internet standards actions. -----------End Extract---------" CHANGE: Delete this. RATIONALE: Pointless since the web came along. "---------Begin Extract--------- The RFC Editor shall publish periodically an "Internet Official Protocol Standards" RFC [1], summarizing the status of all Internet protocol and service specifications. -----------End Extract---------" CHANGE: Delete this. RATIONALE: Pointless since the web came along. 3.16. Changes to Section 6.2 Advancing in the Standards Track "---------Begin Extract--------- Carpenter Expires July 19, 2008 [Page 18] Internet-Draft RFC 2026 Changes January 2008 Change of status shall result in republication of the specification as an RFC, except in the rare case that there have been no changes at all in the specification since the last publication. Generally, desired changes will be "batched" for incorporation at the next level in the standards track. However, deferral of changes to the next standards action on the specification will not always be possible or desirable; for example, an important typographical error, or a technical error that does not represent a change in overall function of the specification, may need to be corrected immediately. In such cases, the IESG or RFC Editor may be asked to republish the RFC (with a new number) with corrections, and this will not reset the minimum time-at-level clock. -----------End Extract---------" CHANGE: Add this: Note that the RFC Editor maintains errata for published RFCs. RATIONALE: Important clarification. "---------Begin Extract--------- When a standards-track specification has not reached the Internet Standard level but has remained at the same maturity level for twenty-four (24) months, and every twelve (12) months thereafter until the status is changed, the IESG shall review the viability of the standardization effort responsible for that specification and the usefulness of the technology. Following each such review, the IESG shall approve termination or continuation of the development effort, at the same time the IESG shall decide to maintain the specification at the same maturity level or to move it to Historic status. This decision shall be communicated to the IETF by electronic mail to the IETF Announce mailing list to allow the Internet community an opportunity to comment. This provision is not intended to threaten a legitimate and active Working Group effort, but rather to provide an administrative mechanism for terminating a moribund effort. -----------End Extract---------" CHANGE: Replace this by: In normal practice, the IESG may be requested to advance any standards-track specification that has been long enough in grade, or to replace or deprecate any IETF document, by the relevant Working Group if it exists, or by one or more individual participants if not. Additionally, when a standards-track specification has not reached Carpenter Expires July 19, 2008 [Page 19] Internet-Draft RFC 2026 Changes January 2008 the highest level, but has remained at the same maturity level for at least the required minimum period plus one year, any participant may request the IESG to review the viability of the standardization effort responsible for that specification and the usefulness of the technology. Such a request should include a proposed action, with a justification and suitable Internet-Drafts if appropriate. Following each such request, the IESG shall approve termination or continuation of the development effort. At the same time the IESG shall decide whether to maintain the specification at the same maturity level or to move it to Historic status. This intention shall be communicated to the IETF by electronic mail to the IETF Announce mailing list to allow the Internet community an opportunity to comment. This provision is not intended to threaten a legitimate and active Working Group effort, but rather to provide an administrative mechanism for reviving or terminating a moribund effort, and for marking obsolete specifications as such. RATIONALE: This shifts the responsibility to initiate advancement or deprecation of specifications to the community. No IESG has ever had the cycles to initiate such actions, and it is much better practice to delegate this responsibility. It also clarifies the difference between normal advancement and the handling of moribund efforts. 3.17. Changes to Section 6.5 Conflict Resolution and Appeals "---------Begin Extract--------- Disputes are possible at various stages during the IETF process. As much as possible the process is designed so that compromises can be made, and genuine consensus achieved, however there are times when even the most reasonable and knowledgeable people are unable to agree. To achieve the goals of openness and fairness, such conflicts must be resolved by a process of open review and discussion. This section specifies the procedures that shall be followed to deal with Internet standards issues that cannot be resolved through the normal processes whereby IETF Working Groups and other Internet Standards Process participants ordinarily reach consensus. -----------End Extract---------" CHANGES: Add the following after the above paragraph: All decisions taken by the IESG and by Working Group chairs and other persons appointed to IETF roles by the IESG are subject to these procedures. RATIONALE: It's possible to read the current sub-section 6.5 as applying only to WG and IESG actions described in section 6. The Carpenter Expires July 19, 2008 [Page 20] Internet-Draft RFC 2026 Changes January 2008 IESG and IAB have preferred to read it as applying to any decision whatever. 3.18. Change to Section 8. NOTICES AND RECORD KEEPING "---------Begin Extract--------- As a practical matter, the formal record of all Internet Standards Process activities is maintained by the IETF Secretariat, and is the responsibility of the IETF Secretariat except that each IETF Working Group is expected to maintain their own email list archive and must make a best effort to ensure that all traffic is captured and included in the archives. -----------End Extract---------" CHANGE: Replace by: As a practical matter, the formal record of all Internet Standards Process activities is maintained by the IETF Secretariat, and is the responsibility of the IETF Secretariat. Each IETF Working Group must maintain an email list archive, which may be that maintained by the Secretariat, and must make a best effort to ensure that all relevant and applicable traffic is captured and included in the archives. It is legitimate to delete irrelevant traffic such as unsolicited commercial email. RATIONALE: Aligning with reality. 3.19. Change to Section 9. VARYING THE PROCESS "---------Begin Extract--------- The proposed variance must detail the problem perceived, explain the precise provision of this document which is causing the need for a variance, and the results of the IESG's considerations including consideration of points (a) through (d) in the previous paragraph. The proposed variance shall be issued as an Internet Draft. The IESG shall then issue an extended Last-Call, of no less than 4 weeks, to allow for community comment upon the proposal. -----------End Extract---------" CHANGE: Add the following text: Alternatively, the proposed variance may be included in the document concerned, in a separate section named "Process Variance". The extended Last-Call requirement will still apply. Carpenter Expires July 19, 2008 [Page 21] Internet-Draft RFC 2026 Changes January 2008 RATIONALE: The present process is clumsy. Why should the variance not be built into the document that will benefit from it? 4. Security Considerations This document has no security implications for the Internet. 5. IANA Considerations This document requires no action by the IANA. 6. Acknowledgements This document was initially constructed on the basis of an earlier draft, draft-carpenter-rfc2026-critique. Useful comments on that draft were made by Eric Gray, Luc Pardon, Pekka Savola, Magnus Westerlund, Jeff Hutzelman, Mike Heard, Alfred Hoenes and others. Later comments and suggestions were made by Douglas Otis, Robert Sayre, Robert Elz, and others. Russ Housley made a very thorough review. Many suggestions in the present document are far from original and many people deserve acknowledgement. Discussions in the former NEWTRK working group and various drafts written in the context of that WG or following its closure, and in the former PESCI design team, were particularly influential. A bibliography of those drafts has not been provided, since they have all expired under Section 2.2 of [RFC2026]. This document was produced using the xml2rfc tool [RFC2629]. 7.

"---------Begin Extract--------- Abstract This memo documents the process used by the Internet community for the standardization of protocols and procedures. It defines the stages in the standardization process, the requirements for moving a document between stages and the types of documents used during this process. It also addresses the intellectual property rights and copyright issues associated with the standards process. -----------End Extract---------" The last sentence is obsolete (see comment on Section 10). "---------Begin Extract--------- 1.1 Internet Standards The Internet, a loosely-organized international collaboration of autonomous, interconnected networks, supports host-to-host communication through voluntary adherence to open protocols and procedures defined by Internet Standards. There are also many isolated interconnected networks, which are not connected to the global Internet but use the Internet Standards. -----------End Extract---------" "Host-to-host" is strictly accurate, but today we tend to emphasise the need for "end-to-end" communication. Also, our experience is that isolated networks tend to get connected sooner or later. However, these are subtle questions and it is proposed to delete the architectural summary from this process document. "---------Begin Extract--------- Carpenter Expires July 19, 2008 [Page 24] Internet-Draft RFC 2026 Changes January 2008 2.1 Requests for Comments (RFCs) Each distinct version of an Internet standards-related specification is published as part of the "Request for Comments" (RFC) document series. This archival series is the official publication channel for Internet standards documents and other publications of the IESG, IAB, and Internet community. RFCs can be obtained from a number of Internet hosts using anonymous FTP, gopher, World Wide Web, and other Internet document-retrieval systems. -----------End Extract---------" Remove the reference to gopher. "---------Begin Extract--------- The RFC series of documents on networking began in 1969 as part of the original ARPA wide-area networking (ARPANET) project (see Appendix A for glossary of acronyms). RFCs cover a wide range of topics in addition to Internet Standards, from early discussion of new research concepts to status memos about the Internet. RFC publication is the direct responsibility of the RFC Editor, under the general direction of the IAB. -----------End Extract---------" Add citations of [RFC4844] and [RFC4071]. "---------Begin Extract--------- The rules for formatting and submitting an RFC are defined in [5]. -----------End Extract---------" Note that [I-D.rfc-editor-rfc2223bis] is applied today. It would probably be better to restate this sentence as: The rules for formatting and submitting an RFC are defined by the RFC Editor. "---------Begin Extract--------- Carpenter Expires July 19, 2008 [Page 25] Internet-Draft RFC 2026 Changes January 2008 3.3 Requirement Levels ... (c) Elective: Implementation of the referenced TS is optional within the domain of applicability of the AS; that is, the AS creates no explicit necessity to apply the TS. However, a particular vendor may decide to implement it, or a particular user may decide that it is a necessity in a specific environment. For example, the DECNET MIB could be seen as valuable in an environment where the DECNET protocol is used. -----------End Extract---------" Update the last sentence: For example, the MIB for a given protocol could be seen as valuable only in an environment where that protocol is used. "---------Begin Extract--------- ... Although TSs and ASs are conceptually separate, in practice a standards-track document may combine an AS and one or more related TSs. -----------End Extract---------" It would be much clearer to the reader if this was said at the beginning of this section. "---------Begin Extract--------- 4.2.3 Procedures for Experimental and Informational RFCs ... Documents proposed for Experimental and Informational RFCs by IETF Working Groups go through IESG review. The review is initiated using the process described in section 6.1.1. -----------End Extract---------" Move up front in this section.
