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 SCC Mirror Committee (SMC) 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). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC TR 15944-6\" throughout. This Standard supersedes CAN/CSA-ISO/IEC TR 15944-6:15 (adopted ISO/IEC TR 15944-6:2009). At the time of publication, ISO/IEC TR 15944-6:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. Scope This part of ISO/IEC 15944 discusses and describes the following three topics of eBusiness modelling: fundamentals of business transaction modelling that describe the conceptual aspects of eBusiness; principles of eBusiness modelling that specify the semantic aspect of business transactions and their components and relationships involved in the business transaction; classification scheme of Open-edi scenarios based on eBusiness modelling.
