1.  Introduction

   Code related to existing IETF standards and ongoing standardization
   efforts may exist and be publicly accessible in many places.  One
   common place is GitHub (https://github.com/), but there are many
   others.  The relationship of the code to corresponding IETF standards
   efforts may be direct, as in the case of a client or server that
   supports protocol defined by an Internet-Draft (I-D)
   (https://www.ietf.org/standards/ids/).  It may be indirect, as in a
   utility that helps analyze network traffic corresponding to this same
   protocol.  The maturity and status of the code may vary considerably,
   including something written quickly as a proof of concept during a
   hackathon, a well established and supported implementation, or a
   legacy project no longer actively developed or maintained.  The code
   must be publicly available, and preferably open source, though other
   terms of use may exist as well.  In all cases, the code may be of
   interest and beneficial to people contributing to the definition,
   implementation, or deployment of an existing or evolving IETF

   standard.  This document provides a set of practices that make it
   easier to identify and find such code.

2.  Existing IETF Processes and Procedures

   The idea that code related to IETF standards is valuable is not new.
   Most IETF participants are familiar with the phrase "rough consensus
   and running code" from the IETF Tao (https://www.ietf.org/tao.html).
   The existence of multiple independently developed and interoperable
   implementations was explicitly required by [RFC1264] for internet
   standards on routing protocols.  Subsequent updates relaxed this
   requirement, but the value of running code is still appreciated, and
   several current RFCs define processes and procedures related to
   running code.

2.1.  Implementation Status

   A simple process that allows authors of I-Ds to record the status of
   known implementations by including an Implementation Status section
   is defined in [RFC7942].  The intent of this section is to allow the
   reader to assign due consideration to I-Ds that have the added
   benefit of running code, which may serve as evidence of valuable
   experimentation and feedback that make the protocols and
   corresponding documents more mature.  However, it is stated that the
   Implementation Status section should be removed from I-Ds before they
   are published as RFCs.  As a result, the value of the code is limited
   to that required to develop the standard, and the mechanism does not
   help find the code once the RFC is published.

2.2.  GitHub

   The IETF chartered the GitHub Integration and Tooling (GIT)
   (https://datatracker.ietf.org/wg/git/about/) working group to
   establish and document practices and policies for use of GitHub by
   working groups for managing their work.  This resulted in [RFC8874],
   which provides a set of guidelines for working groups that choose to
   use GitHub for their work, and [RFC8875], which specifies a set of
   administrative processes and conventions for such working groups.
   Within the working group, the concept of work is limited to the
   development of I-Ds that may eventually become RFCs.  Any concept of
   code is limited to that which appears as text within these documents.
   In many cases, there is additional code that is closely associated
   with the documents but not contained within them.  This code may be
   of interest to the community of people contributing to the
   development of the documents or to the implementation or deployment
   of eventual standards defined by the documents.

2.3.  Hackathon

   The IETF Hackathon [RFC9311] encourages the IETF community to
   collaborate on running code related to existing and evolving Internet
   standards.  Each Hackathon has a wiki that provides a brief
   description of each project.  It is common for there to be one of
   more I-Ds or RFCs associated with each project, and for there to be
   one or more related code repositories.  These resources are often
   listed on the wiki, but they are documented and shared with project
   teams in other ways as well.  After the Hackathon, the wiki remains
   available, but the information within it is typically not updated or
   maintained.

3.  Proposal

   This section specifies a set of practices that use existing
   mechanisms to associate code with an I-D or RFC.  Following these
   practices makes it easier for others working with the I-D or RFC to
   find such code.

3.1.  GitHub Repository

   A GitHub repository (https://docs.github.com/en/github/getting-
   started-with-github/quickstart/create-a-repo#create-a-repository)
   should be setup for an I-D, as outlined in Section 3.2 of RFC 8874
   (https://www.rfc-editor.org/rfc/rfc8874.html#section-3.2).  The
   i-d-template (https://github.com/martinthomson/i-d-template) can be
   used to get started.  It provides useful features, including
   integration with the Datatracker (see Section 3.3).  The resulting
   repository should be associated with the I-D using the Datatracker
   github_repo tag.  This should be done even if GitHub is not to be
   used to collaborate on the I-D.

   A GitHub repository typically exists within a GitHub organization
   (https://docs.github.com/en/organizations/collaborating-with-groups-
   in-organizations/about-organizations).  This is not always the case
   (e.g., a repository in a personal GitHub account), and even when it
   is, the GitHub organization may not be appropriate to associated with
   the I-D.  In the event there is an appropriate GitHub organization,
   it should be associated with the I-D using the Datatracker github_org
   tag.  Examples of such GitHub organizations are:

   *  IETF HTTP Working Group (https://github.com/httpwg)

   *  IETF QUIC Working Group (https://github.com/quicwg)

   *  Internet Architecture Board (https://github.com/intarchboard)

Internet-Draft                  find-code                   January 2023

3.2.  README

   The GitHub repository associated with the I-D should include a README
   (https://docs.github.com/en/github/creating-cloning-and-archiving-
   repositories/creating-a-repository-on-github/about-readmes).  The
   README should include information about the repository, whether or
   not it is being used to collaborate on the I-D, and any code
   associated with the I-D.  The latter may be achieved by including
   direct links to such code or by including links to other resources
   that include information about such code.  These resources may be a
   file, folder, or wiki (https://docs.github.com/en/communities/)
   within the GitHub repository or the GitHub organization associated
   with the I-D.  The QUIC Working Group's Implementations wiki
   (https://github.com/quicwg/base-drafts/wiki/Implementations) is an
   example.

3.3.  Datatracker

   The IETF Datatracker (https://datatracker.ietf.org/) supports the
   association of Additional Resources with a Document (e.g., an I-D or
   RFC) or a Group (e.g., working group (https://datatracker.ietf.org/
   wg/), research group (https://datatracker.ietf.org/rg/)).  An
   Additional Resource can be, among others things, a GitHub
   organization or a GitHub repository.

   It is recommended that this Datatracker mechanism be used to
   associate an appropriate GitHub organization and repository with an
   I-D.  Ideally the organization and repository are setup per the
   guidelines in [RFC8874] and [RFC8875].  In the event the working
   group or research group is not using GitHub, or the I-D has not yet
   been adopted by the group, another GitHub organization or repository
   may be used instead.  A GitHub organization is associated with the
   I-D using the github_org tag.  A GitHub repository is associated with
   the I-D using the github_repo tag.

3.4.  Implementation Status

   An Implementation Status section, as defined [RFC7942], should be
   added to an I-D.  It should state any GitHub organization or GitHub
   repository associated with the I-D.

3.5.  Inline Errata

   In the event an I-D becomes an RFC, people looking for code are less
   likely to reference the Datatracker, and the Implementation Status
   section may have been removed or outdated.  Any GitHub organization
   or GitHub repository associated with the RFC should be made available
   as inline errata (https://mailarchive.ietf.org/arch/msg/edm/
   ku3cd5xTla7tbtohVYWWW7-XTIg/).  An example of this is RFC 3261 with
   inline errata (https://www.rfc-editor.org/rfc/inline-errata/
   rfc3261.html).

3.6.  Known Limitations

   Known limitations of this proposal, and ongoing efforts to address
   them, include the following:

   *  The ability within the Datatracker to associate Additional
      Resources with an I-D or RFC is not well known or used.

      -  The IETF Tools Team (https://www.ietf.org/about/groups/tools/)
         has made the ability to view and edit Additional Resources more
         prominent in the Datatracker.

      -  The functionality is promoted in IETF Hackathons.

   *  The ability and procedure to submit errata is not well known or
      used, and errata that is submitted is not always processed in a
      timely fashion.

      -  An experiment with collaborative annotations (https://rfc-
         annotations.research.icann.org/) for RFCs related to DNS has
         been sponsored by ICANN.

4.  Implementation Status

   The practices proposed in this document are followed by [RFC9311].

5.  Security Considerations

   TBD.

6.  IANA Considerations

   This document has no IANA actions.
