Modeling for dynamic aspect-oriented development

Aspect Oriented Software Development (AOSD) has its roots in the need to deal with requirements that cut across the primary modularization of a software system. On the programming level, mature, industrial-strength tools like the de-facto standard AspectJ exist. However, on the modeling level, there is as yet little support for AOSD. Building on previous work, this paper develops UML modeling support for dynamic AOSD, using standard UML extension mechanisms. We present a generic profile that allows existing UML tools to express AOSD models. We also provide automatic code generation into AspectS, an aspect extension to Smalltalk, and AspectML, an aspect oriented flavor of the ML language. Examples throughout the paper illustrate our approach.
