The Motorola WEAVR: Model Weaving in a Large Industrial Context

This paper reports on the development of an Aspect-Oriented Modeling engine and its initial deployment within the ModelDriven Engineering environment used in production at Motorola. The development environment is presented in detail, through a small example, and the current state of Aspect-Oriented Software Development technologies are discussed in this context. The report presents the particular decision made concerning the design and the deployment of the Motorola WEAVR Aspect-Oriented Modeling engine in light of the particular needs of the telecom system engineering industry. First, we motivate a model weaving approach as opposed to the more traditional aspect modeling, code generation and code-level weaving approaches. Second, we present a novel joinpoint model for transition-oriented state machines, and discuss its use within a large industrial context. Finally, we report on the initial adoption of the weaving engine within production teams and its impact on the development process.
