Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International 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 ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by Technical Committee ISO/TC 68, Financial services, Subcommittee SC 9,
Information exchange for financial services.
This second edition cancels and replaces the first edition (ISO 20022-7:2013), which has been technically
revised.
The main changes are as follows:
— The contents of "Registration Elements" has been harmonized with ISO 20022-1 and ISO/IEC Directives,
Part 1.
— The responsibilities of the Registration Authority have been improved.
— The responsibilities of Submitting Organizations have been updated.
A list of all parts in the ISO 20022 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The ISO 20022 series defines a scalable, methodical process to ensure consistent descriptions of messages
throughout the financial services industry.
The purpose of the ISO 20022 series 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 trigger for the creation of the ISO 20022 series was the rapid growth in the scale and sophistication
of messaging within financial services during the 1990s using the ISO 15022 series. The financial services
industry (hereafter referred to as "the industry") created the first version of the ISO 20022 series as the
successor to the ISO 15022 series in response to that trigger. Since ISO 15022 series, the industry has
broadened the scope from securities to the entire industry for the ISO 20022 series.
The ISO 20022 series is based on open technology standards, which historically have evolved more rapidly
than the industry itself. Consequently, the ISO 20022 series adopted a model-driven approach where the
model of the industry's messaging can evolve separately from the evolution of the messaging technology
standards. The period during which the ISO 20022 series has emerged followed the widespread adoption
of the internet for business. The eXtensible Mark-up Language (XML) emerged as the de facto standard for
document representation on the internet and it became the first syntax for the ISO 20022 series.
The modelling process is further refined into three levels which, in addition to the messaging technology
standard, is why the ISO 20022 series 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
[2]
Framework . The remaining two levels of the 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 Unified Modelling Language (UML) because
it is widely supported and supports multiple levels of abstraction. The models created in accordance with
ISO 20022-1 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 messages. ISO 20022-1 defines a process by
which these models can be created and maintained by the modellers.
The models artefacts are stored in an ISO 20022 Repository (hereafter referred to as "the Repository").
The Repository and physical level artefacts are exposed in a publicly accessible location, such as a website,
serviced by a Registration Authority. The name and contact information of the Registration Authority for
the ISO 20022 series can be found at www.iso.org/maintenance_agencies.
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 definitions and business
processes, and physical syntax implementations.
The ISO 20022 series is organized into the following parts:
— ISO 20022-1 describes the metamodel of all the models and the Repository according to ISO/IEC 19502:2005
(MOF).
— ISO 20022-2 covers the UML profile, a grounding of general UML into a specific subset defined for the
ISO 20022 series (to be used when UML is selected to define the models).
— ISO 20022-3 describes a modelling method to produce models for the ISO 20022 series.
— ISO 20022-4 covers XML schema generation rules to transform a logical level model into a physical level
description in the syntaxes.
— ISO 20022-5 covers business concept model interoperability, and logical model alignment and reverse
engineering.
v
— ISO 20022-6 covers message transport characteristics that define the quality of service required by the
business process definitions so that they can operate successfully.
— This document 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 Physical level
description in ASN.1.
— ISO 20022-9 describes generic guidelines, which are used to define schema generation rules for any
specific syntax.
