RFC 8126/BCP 26, "Guidelines for Writing an IANA Considerations Section in RFCs", defines a framework to ensure that the IANA Considerations section in a document is clear and addresses the various issues that are likely in the operation of a registry. This is a critical function in many protocol frameworks. The current version of BCP 26 was published in 2017 and is the third generation of this document. Given the evolving needs of the IETF community, it is due for an update. The IANABIS working group will consider proposed revisions to BCP 26, given experience gained since the publication of RFC 8126, and ultimately produce a revision for that document. This is the only expected output for the working group. Issues it will consider include: * Additional stipulations around what constitutes valid references for “Specification Required” registries; * Stronger requirements around advice to Designated Experts; * Requirements for the use of Expert Review mailing lists; * Standardizing terms like “registry group,” “registry,” “subregistry”; * Specifying process and restrictions around early allocations; * Adjustments based on IANA’s experience with registries over the past seven years; * Amend and update registry terminology; * Additional registration policies that can allow more flexibility for encouraging and accepting registrations; * Combinations of registration policies with choices by WGs or registrants for specific cases; * A registration policy between FCFS and “Specification Required”, and * A process for using the Internet-Drafts system to create permanent references.
