First experiences on constraining consistency and adaptivity of W2000 models

ABSTRACT

The complexity of Web applications is increasing almost every day. Besides impacting the implementation phase, this complexity must also be suitably managed while modeling the application. The paper argues that a pure modeling notation, like W2000, is not enough to cope with such complexity and proposes an approach, based on meta-modeling and graph transformation, to enforce the consistency of produced artifacts and adapt them in a controlled way. The paper describes the approach, exemplifies it on some simple examples, and sketches the supporting framework on which we are working.
