CSA Preface 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 Standard supersedes CAN/CSA-ISO/IEC 9973:07 (adoption of ISO/IEC 9973:2006). At the time of publication, ISO/IEC 9973:2013 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. 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. Scope This International Standard specifies procedures to be followed in preparing, maintaining and publishing the International Register of Items for any standard whose classes of items are applicable to this register. The items that may be registered fall into several broad categories including: - computer graphics concepts - data structures used by relevant standards - spatial and environmental concepts, and - profiles of relevant standards.
