Modeling architectural change: Architectural scripting and its applications to reconfiguration

We detail the notion of architectural scripting (ASL) as a way to model the dynamic aspects of runtime and deployment-time software architecture. This is complementary to the ability of architecture description languages to model architectures statically in that we define scripting operations to modify architectures at runtime. The scripting operations have as verification of the approach been implemented in an interpreter bundle on the OSGi platform. This implementation is used in our self-management system for generating correct reconfiguration plans in a self-managed system.
