Modeling the REA Enterprise Ontology with a Domain Specific Language

Developing a domain specific language (DSL) to express business policies requires modeling tools for eliciting, applying, and maintaining the knowledge of business experts. This study defines a DSL meta-model and prototype to create visual business models that conform to the Resource, Event, Agent-Enterprise Ontology (REAEO). The meta-model specifies REA-EO modeling components, and the prototype provides a visual interface to design operational and policy-level models. Codegeneration templates then transform design models into executable code that supports business applications. The study describes the capabilities of the prototype and validates its use in the context of a business case.
