Towards a Framework for Reasoning about Aspect Weaving Impact

This paper presents a framework for reasoning about the semantic impact of aspect weaving at the level of early design modeling. The framework is based on semantic consistency between a model and its projection in the woven model. If a weaving preserves the semantic consistency between the model and its projection, then it has no impact on the model. The underlying formalisms are Process Algebras. Firstly, notations for aspect weaving are given. Then, semantic preserved weaving is defined, through which the semantic impact of aspect weaving can be reasoned about. Understanding the impact of weaving can aid developers in foreseeing unintended aspect impacts and increase the reliability of the software, which is especially vital for aspect oriented system refinements.
