Semantics and execution of domain specific models
In this paper we present a two-level approach to extend the abstract syntax of models with concrete semantics in order to execute such models. First, a light-weight execution infrastructure for iteratable models with a generic user interface allows the tool smith to provide arbitrary execution and visualization engine implementations for his or her Domain Specific Language (DSL). Second, as a concrete but nevertheless generic implementation of a simulation engine for behavior models, we present semantic model specifications and a runtime interfacing to the Ptolemy II tool suite as a formally founded backbone for model execution. We present our approach as an open source Eclipse integration to be an extension to the Eclipse modeling projects.
