Self-adaptivity is considered a fundamental feature of autonomic systems. It is thus of fundamental importance to equip the different linguistic and semantic tools that are introduced for achieving the goal of the ASCENS project with the right abstractions and constructs for enabling components of ensembles to adapt to changing environments or to mutated goals. Obviously, adaptivity is possible only if the individual components have the appropriate knowledge (self-awareness) and the appropri- ate capability (self-expression). These features have to be made available at different stages during the development of autonomic components and at run-time. In particular they are relevant both when pro- viding an abstract modeling of the autonomic system and when providing its concrete implementation. But these features do play a key roˆle also when the knowledge handler is designed. This deliverable describes how such mechanisms are realized in ASCENS. We focus, in particular, in abstract mode
