CAN/CSA-ISO/IEC 21000-9:07 (R2017)

This National Standard of Canada is equivalent to International Standard ISO/IEC 21000-9:2005. 1 Scope This International Standard specifies the MPEG-21 file format, in which an MPEG-21 XML document (e.g. Digital Item Declaration (DID)) and some or all of its referenced content can be placed in a single "content package" file. This enables the interchange, editing, and "playback" of MPEG-21 documents.
