[RFC6838][RFC4855]

Note

[RFC2046] specifies that Media Types (formerly known as MIME types) and Media
Subtypes will be assigned and listed by the IANA.

Procedures for registering Media Types can be found in [RFC6838], [RFC4289], 
and [RFC6657]. Additional procedures for registering media types for transfer 
via Real-time Transport Protocol (RTP) can be found in [RFC4855].

Per Section 3.1 of [RFC6838], Standards Tree requests made through IETF
documents will be reviewed and approved by the IESG, while requests made by
other recognized standards organizations will be reviewed by the Designated
Expert in accordance with the Specification Required policy. IANA will verify
that this organization is recognized as a standards organization by the
IESG.

The following is the list of Directories of Content Types and Subtypes. 

Note

Some early registrations have no registration template. The absence of a 
template does not imply a different or reduced registration status.

Note

Per Section 12.5.1 of [RFC9110], use of the "q" parameter name to control 
content negotiation would interfere with any media type parameter having the 
same name. Hence, the media type registry disallows parameters named "q".
