Uniform Resource Identifier (URI) Schemes

Expert(s)

Registry: Mark Baker (primary), Murray Kucherawy (backup). 
CRI Scheme Number field: Unassigned.

Reference

[RFC7595][RFC Errata 4420][RFC8615][RFC-ietf-core-href-29]

Note

Requests for permanent registration must be preceded by mailing list 
review, per Section 7.2 of [RFC7595].
    

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].
