First step towards a domain specific language for self-adaptive systems

Self-adaptive systems are capable of autonomously modifying their behavior at run-time in response to changing environmental conditions. In order to modify the behavior, requirements play an important role, as they tend to change for these systems. For this we need to identify those requirements that are concerned with the adaptability features of the self-adaptive systems. In order to cope with the uncertainty inherent in self-adaptive systems, requirements engineering languages for these systems should include explicit constructs. RELAX is a requirement engineering language tor self-adaptive systems that incorporates uncertainty into the specification of these systems. To go one step further, we aim at developing a domain specific language that would bridge the gap between requirements and the overall system model. The first step that is illustrated in this paper is to build a textual editor for RELAX.
