CSA ISO/IEC 14568:00 (R2019)

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 JTCI) for the Standards Council of Canada (SCC), the I S 0 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 lnfo Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope This International Standard specifies the semantics and syntax of DXL. DXL is a language for exchanging tree-structured charts among CASE tools. DXL is applicable to: 1. exchanging ISO/IEC 8631 compliant 1ree-structured charts (examples of which are shown in annex A (informative) of ISO/IEC 8631); 2. exchanging program flowcharts defined in ISO/IEC 5807 if they are well-structured and don't have data defined in ISO/IEC 5807;  and 3. describing procedure oriented algorithms. This International Standard does not specify: 1. graphical information about a chart, such as the shape, size, and location of symbols; 2. configuration information of a chart, such as its version, author, and file name; or 3. information about the data used in the algorithm described by DXL, such as its structure, reading and writing, and declaration.
