Explicit metaclass programming techniques are presented that enable domain-specific objects to dynamically change their run-time properties. The domain-specific objects are instantiations of a domain model of dynamic system reconfiguration. The domain model is the product of a model-based domain analysis that identified a set of concepts that reflect the types of reconfigurations possible and the system integrity characteristics that must be maintained during such reconfigurations. It is
