8、Published in SwitzerlandBS ISO 20022-6:2013ISO 20022-6:2013(E)ForewordISO (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 commi
9、ttees. 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 I
10、nternational 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 committees is to prepare International Standards. Draft International
11、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 the possibility that some of the elements of this document may be the su

18、y.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 trigger for the creation of this International Standard was the rapid g
19、rowth in the scale and sophistication of messaging within financial services during the 1990s using ISO 15022. The financial services industry (from hereon referred to as “the industry”) created the first version of this International Standard as the successor to ISO 15022 in response to that trigge
20、r. 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 more rapidly than the industry itself. Consequently, this International S
21、tandard 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 followed the widespread adoption of the World Wide Web (the Web) for busi
22、ness. 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 addition to the messaging technology standard, is why this International S
23、tandard 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 the Zachman Framework are equivalent to the implementations and the opera
24、tional levels, respectively. In this part of ISO 20022, 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 accordance with this International Standard are technology in
25、dependent 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. This International Standard defines a method that descri
26、bes 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 repository is available on the World Wide Web and offers public acces
27、s 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 definitions and business processes, and physical syntax implementati
28、ons.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. ISO 20022-2 covers the UML profile, a grounding of general UML into a specific subset defined for this International Standard
29、 (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 covers XML schema generation rules to transform a Logical level model into a Physical level description in the syntaxes. ISO 20022-5 covers
30、 logical model alignment and reverse engineering of existing message syntaxes. This part of ISO 20022 covers message transport characteristics that define the quality of service required by the business process definitions so that they can operate successfully.iv ISO 2013 All rights reservedBS ISO 2

32、 ISO 20022-6:2013BS ISO 20022-6:2013Financial services Universal financial industry message scheme Part 6: Message transport characteristics1 ScopeThis part of ISO 20022 specifies the characteristics of the MessageTransportSystem required for an ISO 20022 BusinessTransaction and MessageDefinition. C
33、hanges to the value of the MessageTransport Characteristics can affect the BusinessTransaction and MessageDefinition.Each BusinessTransaction in the ISO 20022 Repository is associated with a MessageTransportMode. The MessageTransportMode specifies the values for the MessageTransportCharacteristics.T
34、his part of ISO 20022 specifically does not define the wire-level interoperability of message transports. The overall structure is of a layered specification so that ISO 20022 can be implemented over many message transports. This part of ISO 20022 defines only those characteristics required for inte
35、roperability at the business process and message level.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includi
36、ng any amendments) applies.ISO 20022-1, Financial services Universal financial industry message scheme Part 1: Metamodel3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 20022-1 and the following apply.3.1Business Layerhigher or upper layer of the proto
37、col hierarchy that is used to exchange ISO 20022 MessagesNOTE Two layers are defined: a MessageTransport Layer and a Business Layer. The Business Layer is concerned with the business process independently of the mechanics of messaging; effectively independently of technology. The MessageTransport La
38、yer is concerned with the mechanics of messaging; effectively independently of the business process.3.2MessageInstance Headerfirst logical part of the MessageInstance, required to be processed before the rest of the MessageInstanceNOTE It contains information that is common/relevant to any MessageIn
39、stance; as such, it is independent of the message functionality.EXAMPLE The identification of the sender of the MessageInstance.3.3Messaging Application Layerlayer immediately beneath the bottom layer of ISO 20022NOTE This is the Open System Interconnection (OSI) Layer 7 application that delivers me
40、ssages (see 4.1).INTERNATIONAL STANDARD ISO 20022-6:2013(E) ISO 2013 All rights reserved 1BS ISO 20022-6:2013ISO 20022-6:2013(E)EXAMPLE Examples of applications at the Messaging Application Layer are AMQP, ftp, http and SOAP, WebsphereMQ, or SonicMQ.3.4Nameidentifier of somethingNOTE 1 A Name is “pu
41、re”, that is it shall be used for no purpose other than to identify something.NOTE 2 Business logic shall not be based on anything about a name other than its identity.4 Exchange of messages in ISO 200224.1 Layered protocolThe protocol that is used for exchanging ISO 20022 messages is defined as bei
42、ng in two layers sitting directly above the seven layers of the Open System Interconnection (OSI) model. The higher or upper layer is named the Business Layer and deals with MessageInstances. The exchange of MessageInstances is fully described in the Message Choreography and the structure of the Mes
43、sageInstances is fully described by the MessageDefinitions and related MessageRules, Rules and MarketPractices. All of these shall be registered in the ISO 20022 Repository. The Business Layer is equivalent to adding a Layer 9 to the OSI model. The lower or bottom layer is named the MessageTransport
44、 Layer and deals with TransportMessages. The implementation of the MessageTransport Layer may vary and is therefore outside the scope of ISO 20022. The behaviour and structure of the TransportMessages shall therefore not be registered in the ISO 20022 Repository. The Transport Characteristics apply
45、to the Message Transport Layer. The MessageTransport Layer is equivalent to adding a Layer 8 to the OSI model. The layer immediately beneath and therefore outside the ISO 20022 Protocol is the Application Layer. This is the Messaging Application layer. ISO 20022 allows any Messaging Application that
46、 will support the requirements of the MessageTransport Layer. The Messaging Application Layer is Layer 7 of the OSI model.NOTE ISO 7498-1 is referred to as “OSI” throughout this part of ISO 20022.4.2 Layering principlesA single new MessageInstance is created, by the sending business application, for
47、 each business event, i.e. each interaction in a BusinessTransaction. A MessageInstance adheres to the following principles. A MessageInstance shall not contain information about the MessageTransportSystem or the mechanics or mechanism of message sending, transportation, Address, or receipt. A Messa
48、geInstance shall be comprehensible outside of the context of the Transport Message. That is, the MessageInstance shall not require knowledge of the Transport Message to be understood. A MessageInstance is fully described by its MessageDefinition. A MessageInstance refers to Business Participants by
49、their Name. Each instance of a Business Participant has one Name. The instance of the Business Participant shall not be referred to in the MessageTransport Layer.A new Transport Message is created each time a MessageInstance is published by a sending Message Endpoint. A Transport Message adheres to the following principles. A TransportMessage will have a body which only contains the MessageInstance. A TransportMessage may contain headers, footers and envelopes that are meaningful for th
