            Updates to SIPREC correcting Metadata Media Type
               draft-ietf-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.

1.  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

   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
