Domain-specific design pattern instanciation

The use of domain-specific design patterns improves substantially software quality and reduce the development cost since they capture domain knowledge and provide solutions of non trivial design problems in a specific domain. In order to benefit from these advantages, these patterns must be correctly instantiated by application designers. When a pattern is deployed in an application design, some constraints must be preserved to make the pattern instantiation valid. Accordingly, assistance for domain-specific design patterns instantiation has great significance. In this paper we propose a pattern instantiation process that guides the application designers in patterns reuse and prevents them from violating pattern constraints. We implement the proposed process based on model transformation as plug-in to the Eclipse modeling environment. Our proposal is especially intended for the reuse of patterns specific to real-time domain.
