Two messages are linked by arrows to illustrate the conversion process. The Messaging Gateway Message consists of an AQ Property, a Canonical Header, and a Canonical Body. The MQSeries Message consists of a Header and a Body.
Arrows labeled Outbound Propagation point from the Messaging Gateway Message to the MQSeries Message, linking AQ Property to Header, Canonical Header to Header, and Canonical Body to Body. Arrows labeled Inbound Propagation form the same links, but pointing in the other direction.
