3.2. Updating Existing Registrations

3.2. Updating Existing Registrations​

Even after a number has been assigned, some types of registrations contain additional information that may need to be updated over time.

For example, MIME media types, character sets, and language tags typically include more information than just the registered value itself, and may need updates to items such as point-of-contact information, security issues, pointers to updates, and literature references.

In such cases, the document defining the namespace must clearly state who is responsible for maintaining and updating a registration. Depending on the registry, it may be appropriate to specify one or more of:

  • Letting registrants and/or nominated change controllers update their own registrations, subject to the same constraints and review as with new registrations.

  • Allowing attachment of comments to the registration. This can be useful in cases where others have significant objections to a registration, but the author does not agree to change the registration.

  • Designating the IESG, a designated expert, or another entity as having the right to change the registrant associated with a registration and any requirements or conditions on doing so. This is mainly to get around the problem when a registrant cannot be reached in order to make necessary updates.
