Updates to SIPREC correcting SIP-Based Media Recording (SIPREC) to Correct Metadata Media
Type
draft-ietf-sipcore-siprec-fix-mediatype-06
Abstract
The SIP-based Media Recording (SIPREC) protocol is defined by both
Session
"Session Initiation Protocol (SIP) Recording Metadata Metadata" (RFC 7865) and
Session
"Session Recording Protocol Protocol" (RFC 7866). Unfortunately, both RFCs
contradict each other regarding how recording metadata is to be
labeled. In addition, neither RFCs RFC registered the new media type.
This document updates RFC 7866 to align with RFC 7865 when labeling
recording metadata and also registers the new media type.

1. Introduction
The SIP-based Media Recording (SIPREC) protocol is defined by
[RFC7865] and [RFC7866]. The former specifies the use of 'application/rs-
metadata+xml'
"application/rs-metadata+xml" when identifying metadata content,
whereas the latter uses "application/rs-metadata". Since [RFC7865]
defines SIPREC metadata, it was identified as normative, and
[Err7987] was created against [RFC7866] to report the issue. This
document resolves the
errata. erratum.
In addition, as neither document registered the media type with IANA, IANA;
this document rectifies this gap.
2. Updates to RFC 7866
Everywhere
Each instance of the following text occurs: in [RFC7866]:
| application/rs-metadata
Replace
Is replaced with:
| application/rs-metadata+xml
3. Security Considerations
The updates specified in this memo clarify inconsistencies in
published documents with regards regard to identifying recording metadata.
They do not introduce new security considerations beyond those listed
in [RFC7866].
4. IANA Considerations
4.1. Media Type Registration
[RFC7865] defined defines a media type for use with specifying recording
metadata in XML data. This media type is to be used when specifying
recording metadata in SIPREC.
Type name: application
Subtype name: rs-metadata+xml
Required parameters: N/A
Optional parameters: N/A
Encoding considerations: Same as encoding considerations of
application/xml
"application/xml" as specified in [RFC7303].
Security considerations: N/A
Interoperability considerations: Please note that [RFC7866] specified
specifies the use of "application/rs-metadata", which is obsoleted has been
replaced by "application/rs-metadata+xml" in favour of
"application/rs-metadata+xml". RFC 9806.
Published specification: [RFC7865] [RFC-to-be] [RFC9806]
Applications which that use this media type: SIPREC Session Recording Clients (SRC)
(SRCs) and Session Recording Servers (SRS). (SRSs).
Fragment identifier considerations: N/A
Additional information:
Deprecated alias names for this type: N/A
Magic number(s): N/A
File extension(s): N/A
Macintosh file type code(s): N/A
Person & email address to contact for further information: IETF
SIPCORE Working Group (sipcore@ietf.org)
Intended usage: COMMON
Restrictions on usage: There are no restrictions on where this media
type can be used.
