5. IANA Considerations

5.1. The Well-Known URI Registry

This specification updates the registration procedures for the "Well-Known URI" registry, first defined in [RFC5785]; see Section 3.1.

Well-known URIs are registered on the advice of one or more experts, with a Specification Required (using terminology from [RFC8126]).

The experts' primary considerations in evaluating registration requests are:

Conformance to the requirements in Section 3
The availability and stability of the specifying document
The considerations outlined in Section 4

IANA will direct the senders of any incoming registry requests to this document and, if defined, the processes established by the expert(s); typically, this will mean referring them to the registry Web page.

Per this document, IANA has:

Updated the registration procedure to Specification Required.
Added a Status column to the registry and marked all of the existing registrations as permanent.

5.2. The Uniform Resource Identifier (URI) Schemes Registry

This specification adds a field to the registration template of the "Uniform Resource Identifier (URI) Schemes" registry, with the name "Well-Known URI Support" and a default value of -.

If a URI scheme explicitly has been specified to use well-known URIs as per Section 3, the value changes to a reference to that specification. Initial values not equal to - are given in Table 1.
