Autonomic computing is recognized as one of the most??promizing solution to address the increasingly complex task of distributed environments' administration. In this context, many projects relied on software components and architectures to organize such an autonomic management software. However, we observed that the interfaces of a component model are too low-level, difficult to use and still error prone. Therefore, we introduced higher-level languages for the specification of deployment and management policies. These domain specific languages enhance simplicity and consistency of the policies. Our current work is to formally describe the metamodels and the semantics associated with these languages.
