2. 2 Motivation Aspect-orientation (AO) stretches over all development phases No common understanding of aspect-oriented concepts Situation particularly cumbersome for AO beginners Application to specific software development domains difficult Reference Architecture for AOM

10. 10 Outlook Open Issues How to describe aspect refinement policies? How to specify adaptation effects? How to specify join point kinds more explicitly? How to apply multiple languages? Future Work Mapping to AOM & AOP approaches Developing an evaluation framework for AOM approaches Applying Aspect-Orientation to the Model-Driven Development of Ubiquitous Web Applications 1 1 A.
