Introduction

GB/T 27926 defines a scalable and systematic process to ensure the consistency of message descriptions in the entire financial industry. The purpose is fine

Describe the externally observable method of message delivery in the financial industry accurately and completely. This method can be independently verified with running message delivery.

The production of ISO.20022 is based on open technical standards. Usually, the development speed of technical standards is faster than the industry itself. because

Therefore, the document adopts a model-driven approach, in which the industry message collection model can be independently separated from the development of message technology.

ISO.20022 emerged with the widespread commercial adoption of the World Wide Web. Extensible Markup Language (XML) in the form of document representation on the Web

The de facto standard appeared and became the first grammar of ISO.20022.

GB/T 27926 consists of the following parts.

---Part 1.Metamodel;

---Part 2.Overview of UML;

---Part 3.Modeling Guidelines;

---Part 4.XMLSchema generation;

---Part 5.Reverse Engineering;

---Part 6.Message transmission characteristics;

---Part 7.Registration;

---Part 8.ASN.1 generation.

Compared with GB/T 29726-2011, 5 parts were revised and 3 parts were added. The new parts are.

---Part 2.Overview of UML;

---Part 6.Message transmission characteristics;

---Part 8.ASN.1 generation.

part.

In addition to the message technical standards, the modeling process is further refined into three layers, which is why this document is based on four layers. scope layer, concept

Layer, logical layer and physical layer. The first, second and third layers are described in the Unified Modeling Language (UML) because it has been widely used

Support and support multiple layers of abstraction. The models created from this document are technology-independent, as they do not require any specific physical tables

Express or achieve. These models are designed to describe all parts of the message exchange and constitute the definition of the agreement between the participants in the message exchange. This article

The software defines a method that describes the process by which modelers create and maintain these models.

ISO.20022 aims to build a standardized and complete message development plan to improve the efficiency of information exchange and development in the financial industry and reduce message movement.

The maintenance cost of the bank is planned to be composed of the following parts.

---Part 1.Metamodel. The meta-models of all models and libraries are described in the Meta Object Tool (MOF), the purpose is to introduce the modeling method

Method summary, summary of library content, abstract description of the input and output of the library acceptable to the registrar.

---Part 2.Overview of UML. Covers UML profile, which is the basis of a general UML, which is defined by this standard

Specific subset (used when UML is selected to define the model). The purpose is to describe the definition, overall structure, and meta-model of the extension set

Metaclass attributes involved in each layer to UML implementation, so that message developers can better understand the UML extension set and its various levels

UML implementation.

---Part 3.Modeling Guidelines. Describes the modeling method used to generate the model for this document. The purpose is to explain the message model to the modeler

The steps of model establishment ensure the consistency of business components/elements, message components/elements, business transactions and message definitions. This part

It is aimed at the concrete realization of the business of modeling in Part 1 and Part 2.

---Part 4.XMLSchema generation. The purpose is to introduce XMLSchema generation rules, which are used to transform the logical layer model

It is the physical layer of the grammar description.

---Part 5.Reverse Engineering. Covers logical model alignment and reverse engineering of existing message syntax. The purpose is to introduce reverse engineering

The main stages in the process and the inputs, outputs and activities of each stage.

---Part 6.Message transmission characteristics. The purpose is to introduce the parameters of the message transmission system required for business transactions and message definitions.

Confirm the parameter difference in different transmission modes of the message.

---Part 7.Registration. Describes the process of management model registration and physical grammar realization. The purpose is to indicate the applicant institution and registration

Responsibilities and registration process of both parties.

---Part 8.ASN.1 generation. This part gives the ASN.1 grammar generation rules, so that the logical layer model can be integrated through ASN.1

Converted to physical layer description.

General Message Solution for Financial Services and Financial Industry

Part 6.Message Transmission Characteristics

1 Scope

This document specifically clarifies the parameters of the message transmission system required for business transactions and message definitions. Changes in message transmission parameters can affect

Influencing business transactions and message definitions.

Each business transaction module in the ISO.20022 library is related to a message transmission mode, and the message transmission mode determines the message transmission

The value of the parameter.

This document does not clearly define the interoperability at the physical level of message transmission. The overall structure is a layered specification, so ISO.20022 can be

Realized on multi-message transmission. This document only defines the features required for interoperability at the business process and message level.

3 Terms and definitions

The terms and definitions defined in ISO.20022-1 and the following apply to this document.

3.1

Businesslayer

It is used for the exchange of ISO.20022 message information at the upper or upper protocol level.

Note. This document defines two levels, namely the message transmission layer and the business layer. The business layer focuses on the business process and has nothing to do with the message sending mechanism.

Doesn't rely on technology at all. The message transmission layer focuses on the message sending mechanism and does not rely on business processes at all.

3.2

Messageinstanceheader

The first logical part of the message instance module is the part that needs to be processed prior to other parts of the message instance module.

Note. The message instance module covers common or related information of all message instance modules, and does not depend on the message in function.

Example. The identity certificate of the sender of the message instance.

3.3

Messageapplicationlayer

Located at the bottom of the ISO.20022 message standard.

Note. It is the seventh layer used for message transmission in the Open System Interconnection Reference Model (OSI) 7 layers. the application layer (see 4.1).

Example. The protocol of the message application layer includes AMQP, ftp, http, SOAP, WebsphereMQ or SonicMQ, etc.
