Reacting to Functional Changes in Service-Oriented Enterprises

In this paper, we focus on the changes that trigger the modification of a Service-Oriented Enterprise’s function-ality.

It provides mechanisms to interpret a change specification, modify the member services in an SOE, and rearrange their cooperation correspondingly. A domain knowledge provider offers the semantics that facilitates the change reaction process. We also use a logging mechanism to keep track of the change reaction process. I
