The work of preparing Interna
13、tional Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with
14、ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical
15、committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to t
16、he possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20022-5 was prepared by Technical Committee ISO/TC 68, Financial services. This first edition cancels and replaces ISO/T

Click on the link below to take part in the online survey: http:/ BS ISO 20022-5:2013ISO 20022-5:2013(E) vi ISO 2013 All rights reservedIntroduction This International Standard defines a scalable, methodical process to ensure consistent
22、 descriptions of messages throughout the financial services industry. The purpose of this International Standard is to describe precisely and completely the externally observable aspects of financial services messaging in a way that can be verified independently against operational messaging. The tr
23、igger for the creation of this International Standard was the rapid growth in the scale and sophistication of messaging within financial services during the 1990s using ISO 15022. The financial services industry (from here on referred to as “the industry“) created the first version of this Internati
24、onal Standard as the successor to ISO 15022 in response to that trigger. Since ISO 15022, the industry has broadened the scope from securities to the entire industry for this International Standard. This International Standard is based on open technology standards, which historically have evolved mo
25、re rapidly than the industry itself. Consequently, this International Standard adopted a model-driven approach where the model of the industrys messaging can evolve separately from the evolution of the messaging technology standards. The period during which this International Standard has emerged fo
26、llowed the widespread adoption of the World Wide Web (the Web) for business. XML (eXtensible Mark-up Language) emerged as the de facto standard for document representation on the Web and it became the first syntax for ISO 20022. The modelling process is further refined into three levels which, in ad
27、dition to the messaging technology standard, is why this International Standard is based on four levels: the Scope level, the Conceptual level, the Logical level and the Physical level. This four-level approach is based on the first four levels of the Zachman Framework. The remaining two levels of t
28、he Zachman Framework are equivalent to the implementations and the operational levels, respectively. In ISO 20022-1, the first, second and third levels are described in UML (Unified Modelling Language) because it is widely supported and supports multiple levels of abstraction. The models created in
29、accordance with this International Standard are technology independent in that they do not require any particular physical expression or implementation. Such models aim to describe all parts of the message exchange. The models form the definition of the protocol between participants exchanging messa
30、ges. This International Standard defines a method that describes a process by which these models can be created and maintained by the modellers. The models and the Physical level artefacts are stored in a central repository, serviced by a Registration Authority. This International Standards reposito
31、ry is available on the World Wide Web and offers public access for browsing. The Repository is organized into two areas: A DataDictionary containing the industry model elements likely to have further or repeated use. A BusinessProcessCatalogue that contains models describing specific message definit
32、ions and business processes, and physical syntax implementations. This International Standard is organized into the following parts. ISO 20022-1 describes in MOF (Meta-Object Facility) the metamodel of all the models and the Repository. BS ISO 20022-5:2013ISO 20022-5:2013(E) ISO 2013 All rights rese
33、rved vii ISO 20022-2 covers the UML profile, a grounding of general UML into a specific subset defined for this International Standard (to be used when UML is selected to define the models). ISO 20022-3 describes a modelling method to produce models for this International Standard. ISO 20022-4 cover
34、s XML schema generation rules to transform a Logical level model into a Physical level description in the syntaxes. This part of ISO 20022 covers logical model alignment and reverse engineering of existing message syntaxes. ISO 20022-6 covers message transport characteristics that define the quality
35、 of service required by the business process definitions so that they can operate successfully. ISO 20022-7 describes the process of managing the registration of models and physical syntax implementations. ISO 20022-8 gives ASN.1 syntax generation rules to transform a Logical level model into a Phys
36、ical level description in ASN.1. BS ISO 20022-5:2013BS ISO 20022-5:2013INTERNATIONAL STANDARD ISO 20022-5:2013(E) ISO 2013 All rights reserved 1Financial services Universal financial industry message scheme Part 5: Reverse engineering 1 Scope This part of ISO 20022 was prepared to complement ISO 200
37、22-1. The reverse engineering guidelines explain how to extract relevant information from existing IndustryMessageSets in order to prepare the submission to the ISO 20022 Registration Authority of equivalent, ISO 20022 compliant BusinessTransactions and MessageSets. The ISO 20022 Repository will con
38、tain all ISO 20022 compliant BusinessTransactions and MessageSets, as outlined in ISO 20022-1. The approach to be followed for adding ISO 20022 compliant BusinessTransactions and MessageSets to the Repository can be classified according to the following scenarios. a) Case 1: No ISO 20022 compliant B
39、usinessTransactions and MessageSets exist. No IndustryMessageSet exists. EXAMPLE Collective Investment Vehicles. Approach: full development of ISO 20022 compliant BusinessTransactions and MessageSets using ISO 20022-3. b) Case 2: No ISO 20022 compliant BusinessTransactions and MessageSets exist. One
40、 or more IndustryMessagesets exist. EXAMPLE Securities Pre-Trade (FIX MessageSet exists). Approach: conversion of the IndustryMessageSet(s) into ISO 20022 compliant BusinessTransactions and MessageSets, using ISO 20022-5. c) Case 3: ISO 20022 compliant BusinessTransactions and MessageSets exist. One
41、 or more existing IndustryMessageSets exist as well. EXAMPLE Securities Post-Trade (FIX, Omgeo MessageSets exist). BS ISO 20022-5:2013ISO 20022-5:2013(E) 2 ISO 2013 All rights reserved Approach: comparison of the existing IndustryMessageSet(s) with the ISO 20022 compliant BusinessTransactions and Me
42、ssageSets and extension of the ISO 20022 compliant BusinessTransactions and MessageSets as necessary, using ISO 20022-5. This part of ISO 20022 describes the activities of ISO 20022 reverse engineering from the point of view of the user who wants to verify that the business functionality, covered by
43、 his own IndustryMessageSet, is covered by ISO 20022 compliant BusinessTransactions and MessageSets. The intention of this part of ISO 20022 is not to attempt to define a “methodology” for reverse engineering. It describes the following set of required activities. 1) Extract relevant information fro
44、m existing IndustryMessageSets and compare it to the related information in the ISO 20022 Repository. 2) Use the results of this comparison for the development of ISO 20022 compliant BusinessTransactions and MessageSets. 3) Submit the resulting update requests to the Registration Authority. NOTE It
45、is not the intention of reverse engineering to systematically create ISO 20022 compliant versions of all existing IndustryMessageSets. Update requests are always based on a valid business justification. 4) Prepare the migration to the ISO 20022 compliant BusinessTransactions and MessageSets. The mai
46、n objectives of this part of ISO 20022 are to: capture the industry knowledge covered by existing IndustryMessageSets; build upon former standardization efforts in the industry when building ISO 20022 compliant BusinessTransactions and MessageSets; ensure that the resulting ISO 20022 compliant Busin
47、essTransactions and MessageSets cover fully the business scope of existing IndustryMessageSets; maximize interoperability between existing IndustryMessageSets and ISO 20022 compliant BusinessTransactions and MessageSets; support the migration from existing IndustryMessageSets to ISO 20022 compliant
