This topic and its subtopics describe the terminology that you
need to be aware of when working with WS-Notification in WebSphere Application
Server:
Note: The WS-Notification specifications define a
TopicNamespace as
a grouping of topic trees for administrative purposes. Service integration
technologies defines a similar term
topic space as a destination
used for publish and subscribe messaging. Although these concepts are similar,
they are not identical. For example it is possible for there to be a 1-1 relationship
between a WS-Notification topic namespace and a service integration bus topic
space, but in many situations this is not the case. For more information, see
Options for associating a permanent topic namespace with a bus topic space.
