Composing activity aspect diagrams using graph transformation approach

Aspect-oriented paradigm is currently introduced in all phases of the software development with the aim of reducing complexity and enhancing modularity and maintainability already in the early phases. In this paper we propose an approach for aspect-oriented modelling and composition that focuses on UML activity diagrams to capture both crosscutting concerns and core functionality. The approach builds on the use of metamodelling and graph transformations technique to achieve model composition . It takes as an input primary and aspect models described according to a metamodel that we previously defined then produces a model with all aspect models included. The model creation, edition and transformation is carried out using the well-established AToM3 tool. The approach is illustated by an example.
