Reacting to functional changes in service-oriented enterprises

Abstract

In this paper, we focus on the changes that trigger the modification of a service-oriented enterprisepsilas functionality. We present a framework that helps an SOE automatically modify its functional schema based on a change specification. The central component of this framework is a change reaction manager. 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.
