  1. SIPRECRecording Metadata Model for SRS(draft-ram-siprec-metadata-04) IETF80 SIPREC MEETING Parthasarathi R On behalf of the team Team: Paul Kyzivat, Ram Mohan R, R Parthasarathi

  2. Agenda • Changes in draft-ram-siprec-metadata from the previous version • Discuss Open items in Metadata Model • Discuss closed items in Metadata Model • Next Steps

  3. Changes from Previous version • Updated draft with the Metadata model-02 (which was presented in interim meeting after IETF-79)

  4. Metadata Model Recording Session(RS) 1 1..* 0..* Communication Session(CS) Group 1 Extension Data 1 1..* 0..* Communication Session(CS) 1 0.. * 2..* Participant 1 0.. * 1.. * receives sends 0..* 0..* 1 1 Media Stream

  5. Metadata Model: Recording Session Open item: • Optional Stop/Start time attribute has to be added? 1 0..* Recording Session (RS) • Recording Requestor ID • Recording Type (Selective/Persistent) Extension Data 1..* 0..* Communication Session Group (CS Group)

  6. Metadata Model: Communication Session Group Recording Session (RS) Open Issue: • Optional Start/stop time attribute has to be added 1..* 0..* 1 0..* Communication Session Group (CS Group) CS Group unique ID Extension Data 1 1..* Communication Session

  7. Metadata Model: Communication Session Communication Session Group (CS Group) Open Items: • Optional Stop/Start time attribute has to be added? • Whether Session state attribute has to be included to indicate: trying, proceed, early, confirmed, terminated 1 1..* 1 0..* Communication Session (CS) • CS Unique ID • Call terminate Reason Extension Data 0..* 2..* Participant

  8. Metadata Model: Participant 0..* 2..* Communication Session Open Items: • Optional Stop/Start time attribute has to be added? 1 0..* Participant • AoR • Name Extension Data 0.. * 1.. * receives sends 0..* 0..* Media Stream

  9. Metadata Model: Media Stream Participant Open item: • Change 4.5.1 3rd bullet as “"Codec params - represents codec description of RS SDP" Closed item: • In case Media is “inactive” from the beginning of the session, start-time is not required to be passed across. The text will be added to clarify 1 0..* Media Stream • Start Time • End Time • Codec (& codec params) • Media Stream Reference Extension Data 0.. * 1.. * receives sends 0..* 0..*

  10. Metadata Model: Media Stream Open items: • Is it required to model media streams that are not recorded[ e.g SRC offered certain media types but SRS choose to accept only subset of them]

  11. Next steps • Request for review of draft-ietf-siprec-metadata-00 in the mailer • WGLC of metadata model draft? • Align metadata format draft with metadata model draft
