Model-Driven Architecture for Agent-Based Systems

摘要

The Model Driven Architecture (MDA) approach uses a platformindependent model to define system functionality, or requirements, using some specification language. The requirements are then translated to a platform-specific model for implementation. An agent architecture based on the human cognitive model of planning, the Cognitive Agent Architecture (Cougaar) is selected for the implementation platform. The resulting Cougaar MDA prescribes certain kinds of models to be used, how those models may be prepared and the relationships of the different kinds of models. Using the existing Cougaar architecture, the level of application composition is elevated from individual components to dcmain level model specifications in order to generate software artifacts. The software artifacts generation is based on a metarnodel. Each compcnent maps to a UML structured component which is then converted into multiple artifacts: Cougaar/Java code, documentation, and test cases.
