Compiling process graphs into executable code

Model-driven architecture envisions a paradigm shift as dramatic as the one from low-level assembler languages to high-level programming languages. In order for this vision to become reality, algorithms are needed that compile models of software systems into deployable and executable implementations. This paper discusses two algorithms that provide such transformations for process graph models in a business process or workflow environment and produce executable programs based on Web services and orchestration languages. The reverse transformations back from executable programs to process graphs are also described.
