Message Templates

Message templates, also called RAP data stream (RDS) templates, are XML documents that represent the data structure of specific message types.

The Publisher API and subscribers look up information about message formats in a set of RDS templates. The Publisher API uses templates to build the messages it sends to subscribers. Subscribers use templates to parse messages and store them in a database.

There are two ways to integrate RDS templates used by publishers and subscribers with message definitions in the model.

Import a RAP message that is defined in a message template (an RDS template XML file).
Generate RAP template files from RAP messages defined in the model.
