Metadata Contents
The recording metadata contains a set of related elements which define the recording session. A recording session may contain zero or more communication sessions and/or communication session groups. A communication session represents a call instance; a communication session group represents a related group of communication sessions. A recording session is composed of a sequence of complex element types. Not all element types are required to describe a recording session initiated from the Oracle® Enterprise Session Border Controller. The recording session XML schema defines the following element types:
- dataMode - partial or complete metadata description (required)
- group - a collection of related communication sessions
- session - a single communication session of two or more participants (required)
- participant - a SIP endpoint representation (required)
- stream - a media stream
- extensiondata - application specific data outside of the SIPREC scope.
The recording agent generates dataMode, session, participant, and stream elements. Extension data is attached to other elements within the metadata through the use of the parent attribute. The recording metadata is defined as a sequence of element types; therefore all associations between elements are represented as references to element identifiers.
The state of the metadata within a recording session reflects the state of the communication session(s) which is being recorded. SIPREC implements stop-times and reason codes when communication sessions end within a recording session. Once a communication session, participant, or media stream has been marked as 'stopped' and accepted by the SRS, the metadata item is removed from the current metadata state. In addition, media lines within the SDP or the recording session may be re-used/re-labeled for reuse if new communication sessions and media streams are created within the recording session.
The XML schema for the recording metadata is defined in the IETF draft RFC draft-ram-siprec-metadata-format-02 [7].
The ACLI command to show recorded metadata is show rec. For more information on this command see the section, Show rec.
