Crisis Management Systems: A Case Study for Aspect-Oriented Modeling -- Requirements Modeling with the Aspect-oriented User Requirements Notation (AoURN): A Case Study -- Relating Feature Models to Other Models of a Software Product Line -- Aspect-Oriented Development Using Protocol Modeling -- Using VCL as an Aspect-Oriented Approach to Requirements Modelling -- Workflow Design Using Fragment Composition -- Modeling the Car Crash Crisis Management System Using HiLA -- Aspect-Oriented Design with Reusable Aspect Models -- A Graph-Based Aspect Interference Detection Approach for UML-Based Aspect-Oriented Models -- Discovery of Stable Abstractions for Aspect-Oriented Composition in the Car Crash Management Domain.

This volume, the seventh in the Transactions on Aspect-Oriented Software Development series, assembles nine papers that all apply different aspect-oriented modeling techniques to the same case study. The case study, a relatively complex crisis management system, is presented in detail in the first paper. In this way, a wide variety of notations and abstraction techniques for modeling aspect systems are demonstrated and evaluated for the same case study, allowing readers to understand the relative strengths of each approach and encouraging cross-fertilization among the techniques.
