Semantics of Architectural Specifications in CASL

  title={Semantics of Architectural Specifications in CASL},
  author={Lutz Schr{\"o}der and Till Mossakowski and Andrzej Tarlecki and Bartek Klin and Piotr Hoffman},
We present a semantics for architectural specifications in Casl, including an extended static analysis compatible with modeltheoretic requirements. The main obstacle here is the lack of amalgamation for Casl models. To circumvent this problem, we extend the Casl logic by introducing enriched signatures, where subsort embeddings form a category rather than just a preorder. The extended model functor has amalgamation, which makes it possible to express the amalgamability conditions in the… CONTINUE READING
