The recent advances in network-based software applications and the advent of ubiquitous computing are pushing us inevitably toward a world of autonomous software architectures. This trend has spurred the revitalization of agent technology as a complement to the object paradigm for a variety of modern application domains, including e-commerce, software development environments, and personal assistants. There is explicit evidence indicating the penetration of software agents is also high for systems used in military and government contexts [ 2, 8]. Agents, like objects, provide services to their clients, but are recognizably different from objects as seen from an architectural point of view [ 3, 5, 8]. Unlike objects, an agent is an autonomous entity that takes the initiative to achieve system goals and represent software users [ 2, 3].
