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