Information technology - Multimedia framework (MPEG-21) - Part 3: Digital Item Identification (Adopted ISO/IEC 21000-3:2003, first edition, 2003-04-01)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.
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.
