Aspectual Oriented weaving technology in Model Driven Architecture

Model Driven Architecture (MDA) is a development methodology taking model as center, it shift the focus of software development activity from coding to modeling, which is initiated by the Object Manage Group and based on UML and other standard etc. Aspect-Oriented Programming (AOP) is an emerging software engineering paradigm that improves separation of cross-cutting concerns as aspect in a program. Separation of concerns is an important principle for designing high quality software systems and is both applied in the MDA and Aspect-Oriented Software Development (AOSD). The AOSD and MDA techniques seem to be complementary to each other; We provided a weaving-based model composition framework, adopted weaving technology in model composition. Model composition could be carried out automatically through model weaving framework. This is also an attempt to combine model transformation and model composition.
