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).
At the time of publication, ISO/IEC 21000-10:2006 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.
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. 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.
Scope
This Part of ISO/IEC 21000, entitled Digital Item Processing (DIP), specifies the syntax and semantics of tools that may be used to process Digital Items. The tools provide a normative set of tools that specify the processing of a Digital Item in a predefined manner.
This technology is specified in one normative clause and three normative annexes:
- Digital Item Methods:
Digital Item Methods (Clause 5) specifies the set of tools enabling Digital Item Users to include sequences of instructions for adding predefined functionality to a Digital Item. Such a sequence of instructions is a Digital Item Method. Digital Item Methods are authored with the Digital Item Method Language (see 5.2) which includes bindings to Digital Item Base Operations (see 5.4). For extended functionality, Digital Item eXtension Operations (see 5.6) allow such processing to be implemented more efficiently in a higher level programming language. Tools for integrating Digital Item Methods into Digital Item Declarations are also specified (see 5.3).
- ECMAScript bindings for Digital Item Base Operations:
Annex A specifies the ECMAScript bindings for the Digital Item Base Operations described in 5.3.
- Java bindings for Digital Item Base Operations:
Annex B specifies the Java bindings for the Digital Item Base Operations described in 5.4.
- Calling Java based DIXOs from Digital Item Methods:
Annex C specifies the mechanism for calling Java based Digital Item eXtension Operations. Digital Item eXtension Operations are described in 5.6.
