Topic mapping

This text describes the topic mapping used for publishing and subscribing between WebSphere Application Server and a WebSphere MQ network.

A topic is a character string that describes the nature of the data for publication or subscription. A topic mapping is an association (specified when the administrator creates or updates the WebSphere MQ link) that defines which messages published in WebSphere Application Server or one of the message brokers in the WebSphere MQ network, should be forwarded to the other publish/subscribe system. For example, if a topic mapping is set up for "stock/IBM" with a direction from the WebSphere Application Server service integration bus to WebSphere MQ, the publish/subscribe bridge attaches as a subscriber to the relevant topic space and so receives messages when they are published to the topic. The publish/subscribe bridge then attaches as a publisher to, for example, the WebSphere Business Integration Event Broker, and republishes the message into the WebSphere MQ network where it can be received by message broker subscribers.
