sipcore D. Mongrain Internet-Draft Motorola Solutions Updates: 7866 (if approved) 2 December 2024 Intended status: Informational Expires: 5 June 2025 Updates to SIPREC correcting Metadata Media Type draft-mongrain-sipcore-siprec-fix-mediatype-00 Abstract SIP-based Media Recording (SIPREC) protocol is defined by both RFC 7865 and RFC 7866. Unfortunately both RFCs contradict each other regarding how recording metadata is to be labeled. In addition, neither RFCs registered the new media type. This document updates RFC 7866 to align with RFC 7865 when labeling recording metadata and registers the new media type. About This Document This note is to be removed before publishing as an RFC.

Introduction SIPREC is defined by [RFC7865] and [RFC7866]. The former specifies the use of 'application/rs-metadata+xml' when identifying metadata content whereas the latter uses "application/rs-metadata". And since neither documents registered the media type with IANA, this document does. 2. Conventions and Definitions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 3. Updates to RFC 7866 Everywhere the following text occurs: application/rs-metadata Mongrain Expires 5 June 2025 [Page 2] Internet-Draft Fix SIPREC Metadata Media Type December 2024 Replace with: application/rs-metadata+xml 4. Security Considerations The updates specified in this memo clarifies inconsistencies in published documents with regards to identifying recording metadata. It introduces no new security considerations beyond those listed in [RFC7866]. 5. IANA Considerations 5.1. Media Type Registration [RFC7865] defined a MIME media type for use with specifying recording metadata in XML data. This media type MUST 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 as specified in [RFC7303]. Security considerations: See Section 4. Interoperability considerations: Please note that [RFC7866] specified the use of "application/rs-metadata", which this document corrects. Published specification: [RFC7865] Applications which use this media type: SIPREC Clients (SRC) and Servers (SRS). Fragment identifier considerations: N/A Additional information: Deprecated alias names for this type: N/A Magic number(s): N/A Mongrain Expires 5 June 2025 [Page 3] Internet-Draft Fix SIPREC Metadata Media Type December 2024 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.
