Adding power and flexibility to the WebSphere Service Registry and Repository subscription and notification framework

You can subscribe to objects in WebSphere Service Registry and Repository (WSRR) and be notified when these objects change. WSRR releases have added power and flexibility to the subscription and notification framework, both in the scope of objects you can subscribe to, and the ways in which you can be notified. This article describes the subscription and notification framework and shows you how to use the new capabilities in WSRR V7.5 and V8.0.
