On the Modular Specification of Non-Functional Properties in DSVLs

In previous work we have presented an approach to monitor nonfunctional properties of systems modeled in terms of domain specific visual languages using observers. In this work we present an approach to decouple the definition of observers behavior and systems behavior. Having a library with different kinds of observers behavior, and having the behavioral definition of the system, weaving links can be established among them in order to include observers in the system behavioral specification.
