Abstract: A computer-executable application is provided with access to resources generated using a principal model. A decoration model associated with the principal model is instantiated for use by the application. The application is provided with access to an object of the decoration model responsive to a request by the application to access an object of the principal model. The decoration model object corresponds to the principal model object.

Abstract: A method for implementing a model-driven architecture, including defining a principal model having a plurality of classes, references, attributes, and associations between any of the classes, the model configured to facilitate the automatic generation of at least one resource for use by a computer-executable application, where a change to the principal model subsequent to performing the automatic generation requires the automatic generation be performed again in order to effect the change for use by the application, defining a decoration model having a class, reference, and attribute for any corresponding one of the primary model classes, references, and attributes, where a change to the decoration model subsequent to performing the automatic generation does not require the automatic generation be performed again in order to effect the change for use by the application, mapping the decoration model to the principal model, and storing both of the models on a computer-readable medium.
