A topic space mapping allows subscribers on the local topic space to receive messages published in the foreign topic space. You can configure topic space mappings between a local service integration bus and a foreign service integration bus.
A topic space mapping allows subscribers on the local topic space to receive messages published in the foreign topic space. For publications to flow from the local topic space into the foreign bus, an equivalent topic space mapping is required by the foreign bus.
If you want to publish messages from a local bus to a foreign bus that is linked indirectly through a third bus, you must configure topic space mappings between the local bus and the intermediate bus, and between the intermediate bus and the foreign bus. The messages can be for publication to the foreign bus only, or to all three buses. If you want to publish messages only to the local and foreign buses, these two buses must be connected directly.
If you want to publish messages from a local service integration bus to a foreign bus representing a WebSphere® MQ network, you must define topic space mappings on the broker profile associated with the WebSphere MQ link, see Defining topic mappings.
For more details about the foreign bus and publish/subscribe messaging between buses see Foreign buses.
