Multi-Stage Aspect-Oriented Composition of Component-Based Applications

The creation of distributed applications requires sophisticated compositions, as various components - supporting application logic or non-functional requirements - must be assembled and configured in an operational application. Aspect-oriented middleware has contributed to improving the modularization of such complex applications, by supporting a component model that offers aspect-oriented composition alongside the traditional composition of provided and required interfaces. One of the recent advances in AO middleware is the ability to express dynamic compositions that depend on the evaluation of available context information - some of this information may only be available at deployment time.
