Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet- Drafts as reference material or to cite them other than as "work in progress." The list of current Internet-Drafts can be accessed at http://www.ietf.org/1id-abstracts.html The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html.

Full Copyright Statement Introduction IETF specifications do not receive formal review until they are submitted to the IESG. Hence, significant problems with a specification often are not detected until considerable effort has been wasted and changes to fix the problems are difficult to add. We can speculate that this problem explains a large part of the long tail in the distribution of IESG document approval times, as well as a perception that the IESG has too much authority. The procedure described in this document is intended to solve, or palliate, a number of related problems that have been observed in the IETF process [PROBLEM]: * overload of the IESG (leading to delay) * perception that authority and influence in the IETF are concentrated in too few hands * submission of documents to the IESG that still have significant problems (leading to delay) * failure to detect fundamental problems and Internet- wide issues at an early stage Particularly because of the last point, it is impossible to resolve all these problems simply by giving additional responsibility to working groups themselves. An additional procedure is needed. The procedure specified here calls for a team of 'sirs' to 'card'. The term 'card' is used for textiles and pubs. The former usage removes detritus from textiles and prepares it for weaving. The latter vets participants at the door. The term also is an acronym for 'Careful Additional Review of Documents.' The carding procedure initially makes no change to the formal process of IETF document development, review, approval, and publication. It is an additional procedure intended to tackle the problems listed above. If successful, it can be transformed into a formal process in due course. The basic model is that the IETF will create a team of Senior IETF Reviewers (SIRs, who need be neither male nor knighted) chosen in a way designed to create trust, and that all documents must receive a certain number of reviews by SIRs, prior to being submitted to the IESG or the RFC Editor for publication. Furthermore, review at a very early stage is strongly encouraged. The model is intended to be compatible with, and complementary to, existing mechanisms such as the various Directorates within the IETF and the MIB Doctor system. The remainder of this document described how the team of SIRs is created and refreshed, how the review process works, and how it is used by document authors and working groups to achieve their objectives. 2. SIRS 2.1. The Body of Senior Internet Reviewers 2.1.1. Initial Set of SIRs With approximately 200 RFCs published per year, and with most of them having existed in multiple Internet Drafts, a large team of SIRs is needed. A target of 100 people is suggested. The goal is to identify a team of people with adequate experience contributing to IETF technical work, who are likely to be trusted as a group to be both technically expert and unbiased. The initial team is defined by objective criteria, to avoid any bias in their selection. It will consist of: * all current IAB members * all former IAB and IESG members, and former WG Chairs, who the Secretariat can contact and who are willing to serve * all current MIB Doctors * all members of existing IETF Directorates * all authors of at least three RFCs, who the Secretariat can contact and who are willing to serve * (other suggestions???) (Current IESG Area Directors are excluded from the pool.) 2.1.2. Addition and Removal of SIRs The team of SIRs is augmented each year [[schedule TBD]] by a public nomination process and a voting procedure (TBD) among the existing SIRs. SIRs who do not produce at least [[five ??]] reviews in a given year will be retired from the team. In extremis, SIR status may be removed by a simple majority vote of the team of SIRs. 2.2. Obtaining SIR Participation For Working Group documents, Working Groups solicit the assistance of SIRs. That is, the general IETF community controls who is authorized as a SIR, but WGs control which specific SIRs provides the formal review that is needed for a given document. A primary goal of this proposal is to ensure that Working Groups benefit from broad experience in the design of Internet technology. Hence it is entirely reasonable that some SIRs reviewing a given document should be subject matter experts. However the full set of input from SIRs is substantially more useful when it includes SIRs from other areas. In particular, cross- area review makes it more likely that architectural and operational impacts outside of the subject matter will be detected. It is therefore strongly recommended that WGs seek a diverse set of SIRs to participate in evaluations, able to cover most if not all IETF Areas between them. Each WG will make its own decision about how its SIRs are selected (e.g. chosen by the WG Chairs, chosen by the document authors concerned, etc.) For individual submissions, the document author(s) will solicit SIR reviews, according to the same principles applied to Working Group documents. There is no fixed number of SIR reviews required prior to submission to the IESG or the RFC Editor. However, it is likely that drafts with at least three positive reviews from SIRs in different areas will experience much shorter IESG review cycles than drafts with fewer positive reviews. Other common sense rules will apply; for example a MIB that has not been reviewed by a MIB Doctor is unlikely to be published. In all likelihood, Drafts without reviews will get worse IESG response time than today, whereas Drafts with reviews will be processed much more rapidly, especially as the IESG's confidence in the SIR procedure increases. 3. CARDING 3.1. Reviewing in Public The current list of SIRs will be available on the IETF web site. All reviews will be published on the web site, with adequate tooling (similar to or linked to the ID Tracker) so that every review can be readily found. In fact, a WG or document author in need of reviews should be able to request them through the web site. 3.2. Form of a Review Each review must start with a summary statement chosen from or adapted from the following list: * This draft is ready for publication as a [type] RFC. * This draft is on the right track but has open issues, described in the review. * This draft has serious issues, described in the review, and needs to be rethought. * This draft has very fundamental issues, described in the review, and further work is not recommended. The length of a review will vary greatly according to circumstances, and it is acceptable for purely editorial comments to be sent privately. All substantive comments must be included in the public review. SIRs should review for all kinds of problems, from basic architectural or security issues, Internet-wide impact, technical nits, problems of form and format (such as IANA Considerations or incorrect references), and editorial issues. As a draft progresses from its initial, "-00" version towards one that is ready for submission, successive SIR reviews should progress from the general architectural level to the editorial level. The intention is that before a draft is submitted by a WG to the IESG, or by an individual to the RFC Editor, it has already benefited from a level of review equivalent to that traditionally applied by the IESG. 3.3. Iterative Carding The carding of textiles is an iterative process, and so is the carding of documents by SIRs. It is not required that every version of an Internet Draft should be submitted for SIR review. However, it is advisable to request reviews at the very beginning (to check for fundamental issues), as major technical issues are resolved, and again just before the document is submitted for IESG approval. Thus three SIR review cycles per document may be considered the minimum. Both Working Groups and individual submitters should realise that carding should start early (to detect and hopefully fix fundamental problems) and be repeated as often as needed (to avoid submitting inadequate documents to the IESG). By these means, it should be possible to avoid most cases where a document spends a long time in IESG review or, worse, is fundamentally unacceptable to the IESG. 4. SECURITY CONSIDERATIONS This document does not directly impact the operational security of the Internet. 5. ACKNOWLEDGEMENTS Your name could go here!
