            Updates to SIPREC correcting Metadata Media Type
               draft-ietf-sipcore-siprec-fix-mediatype-05

Abstract

   The SIP-based Media Recording (SIPREC) protocol is defined by both
   Session Initiation Protocol (SIP) Recording Metadata (RFC 7865) and
   Session Recording Protocol (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

   SIP-based Media Recording (SIPREC) protocol 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".  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.

   In addition, as neither document registered the media type with IANA,
   this document rectifies this gap.

2.  Updates to RFC 7866

   Everywhere the following text occurs:

      application/rs-metadata

   Replace with:

      application/rs-metadata+xml

3.  Security Considerations

   The updates specified in this memo clarify inconsistencies in
   published documents with regards 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 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 as specified in [RFC7303].

   Security considerations: See Section 3.

   Interoperability considerations: Please note that [RFC7866] specified
   the use of "application/rs-metadata", which is obsoleted in favour of
   "application/rs-metadata+xml".

   Published specification: [RFC7865] [RFC-to-be]

   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

      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.
