This paper describes and empirically evaluates a new model-driven framework, called Modeling Turnpike (or mTurnpike), which allows developers to effectively model and program domain concepts (ideas and mechanisms specific to a particular business or technology domain). By leveraging UML metamodeling and attribute-oriented programming, mTurnpike provides an abstraction to represent domain concepts at the modeling and programming layers simultaneously. The frontend system of mTurnpike transforms domain concepts between the modeling and programming layers. Its backend system combines domain models and programs, and transforms them to the final (compilable) source code. This paper focuses on the mTurnpike frontend system, and describes its design, implementation and performance implications.
