CSA ISO/IEC 15944-20:16 (R2021)
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 15944-20 throughout.
At the time of publication, ISO/IEC 15944-20:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA 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 TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
1.1 Statement of scope
ISO/IEC 15944-20 specifies the properties of Base Functional Specification View (FSV) Standards in order to best meet the requirements of the Business Operational View (BOV) with interoperable implementations. Base FSV standards exhibiting these properties support business transactions beyond those that are in compliance with Open-edi scenarios (OeS). Additional beneficial business transactions may also be supported between a given IT system and IT system(s) outside of the Open-edi scenarios for which they were designed.
These base FSV standards address those aspects of interoperability between IT systems used among Parties of the Open-edi Community participating in the scenario. Examples of such standards include the choreography of interchanges among systems, and the foundational structure and syntax used to express Information Bundles (IB) in the interchanges.
ISO/IEC 15944-20 does not specify the properties of FSV implementations related to the interfaces of the Open-edi support infrastructure (OeSI) to the technology of the Information Processing Domain (IPD) in which they are being used. Those are the interfaces of the services offered to Decision Making Applications (DMA), and to the inter-working of the Open-edi support entities (OeSE) of the OeSI. How these OeSEs interact are self-contained within a Party's IPD and have no interworking relationship with those OeSEs of other IT system(s) in the scenario.
The Open-edi Reference Model (ISO/IEC 14662:2010, Clause 0.3) observes the following regarding interoperability:
Only the external behaviour of Open-edi Parties affects the interoperability of Open-edi Systems.
