The message model

This topic introduces the concept of the message model and describes its associated components.

The message model consists of the following components:

See Message modeling concepts for a summary of these components and the relationship between them.

The majority of your model content is described by message files. These files use XML Schema to represent your messages. XML Schema is an international standard which defines a language for describing the structure of XML documents. It is ideally suited to describing the messages which flow between business applications, and it is widely used in the business community for this purpose.

Each message file describes both the logical structure of your messages, and the physical formats that describe the precise appearance of your message bit stream during transmission. The service flow project tools use the MRM domain, which includes physical format information. This tells the parser exactly how to parse the message bit stream.

See Message modeling process to understand the different ways that you create and populate message files. See Physical formats for messages for a description of the physical formats available to you.
