We introduce a Component Coordination Model for supporting the design of computer-based systems using middleware infrastructure and a method for incorporating this model into the systems. We focus only on exposing the design for customization and composition of component-based systems to be separated from the design of components.These separated concerns (coordination and computation) form the principal concept of our model. They encapsulate the implementation details of component co-ordinations and interactions, in the distributed computing environment, into coordination entities (Interaction Entities). We describe the customization and composition abstraction levels for specifying common component framework including policies, protocols, and rules that manage and coordinate the component interdependencies in a given use-context.
