We present an approach to aspect specification based on the Protocol Modelling paradigm, which uses CSP parallel composition as the mechanism for combining partial behaviour specifications. Using the Protocol Modelling approach enables local reasoning about the behaviour of the whole model based on knowledge of behaviour of the composed aspects, and we present the proof of this key property in this paper. We describe how Protocol Modelling allows the definition of aspect join points and weaving relationships at the model level, and how different aspects may use different abstractions over the same domain. We illustrate this using a small case example.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
