This third part of MPEG-21 (ISO/IEC 21000-3), entitled Digital Item Identification (DII), specifies How to uniquely identify Digital Items (and parts thereof);- How to uniquely identify IP related to the Digital Items (and parts thereof), for example abstractions;- How to uniquely identify Description Schemes;- The relationship between Digital Items (and parts thereof) and existing identification systems. Annex C contains a list of relevant identification systems. This is not an exhaustive list and is subject to change over time;- The relationship between Digital Items (and parts thereof) and relevant description schemes. Annex C contains a list of relevant description schemes. This is not an exhaustive list and is subject to change over time.ISO/IEC 21000-3 specification does not specify:- New identification systems for the content elements for which identification and description schemes already exist and are in use (e.g., ISO/IEC 21000-3 does not attempt to replace the ISRC, as defined in ISO 3901, for sound recordings;- Normative description schemes for describing content.
