Providing Support for Model Composition in Metamodels

In Aspect-Oriented Modeling (AOM), a design is described using a set of design views. It is sometimes necessary to compose the views to obtain an integrated view that can be analyzed by tools. Analysis can uncover conflicts and interactions that give rise to undesirable emergent behavior. Design models tend to have complex structures and thus manual model composition can be arduous and error-prone. Tools that automate significant parts of model composition are needed if AOM is to gain industrial acceptance. One way of providing automated support for composing models written in a particular language is to define model composition behavior in the metamodel defining the language.
