Uniform Resource Identifier (URI) Schemes

Expert(s)

  • Registry: Mark Baker (primary), Murray Kucherawy (backup)
  • CRI Scheme Number field: Henk Birkholz, Marco Tiloca

Reference

Note

Requests for permanent registration must be preceded by mailing list review, per Section 7.2 of RFC 7595.

Note

Schemes for which the primary reference is an Internet-Draft are generally considered to be provisional until the I-D is approved by the IETF for RFC publication, even when the specification requests permanent registration.

Note

The CRI Scheme Number column registers numeric identifiers for the URI Schemes registered. Registrants for the Uniform Resource Identifier (URI) Schemes Registry may indicate that there are special requirements on the CRI scheme number to be assigned for the new URI Scheme.

If that is not the case, IANA will assign a value autonomously. If there is a special requirement, the value will be allocated via Expert Review by the Designated Expert for the "CRI Scheme Number" column.

Registrants that want to indicate special requirements on a CRI Scheme Number for a new URI-Scheme assignment are encouraged to notify the core-parameters@ietf.org mailing list of these requirements early. For more information, see RFC-ietf-core-href-29.
