This journal is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems.

This volume presents two regular revised papers, a guest editors' introduction, and six papers in a special section that have been through a careful peer reviewing process by the journal's Editorial Board. Besides a wide range of topics from software design to implementation of aspect-oriented languages, the six papers of the special section concentrate on AOP systems, software and middleware.

The LNCS journal Transactions on Aspect-Oriented Software Development is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus of the journal is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems. This volume, the fifth in the Transactions on Aspect-Oriented Software Development series, contains three papers submitted through the regular channel, and three papers on the special focus area of aspects, dependencies and interactions. The first two papers concentrate on applications of AOSD to the fields of scheduling of web applications and operations research, respectively, while the third paper applies the technique of bisimulation to aspect-oriented languages. The special focus area on aspects, dependencies and interactions is introduced by the guest editors Ruzanna Chitchyan, Johan Fabry, Shmuel Katz, and Arend Rensink.

– Those who want to learn about AOM ?nd in this special issue a concise collection of descriptions of solid and mature AOM approaches. They only have to take the time to understand one case study in order to appreciate the sample models shown in all papers. – Those who want to apply AOM for a particular purpose and are looking for the most appropriate AOM technique can use the papers presented in this specialissue to identify the mostpromisingapproach(es).By identifying similarities between their problem and the case study they should be able to determine candidate AOM approaches easily. – Those working on their own AOM approach can readily identify approaches that were able to handle concerns that their own approach is not able to handle elegantly. This stimulates cross-fertilization between approaches and collaborative research. – Thoseengineering researchersthat areworkingon enhancing softwaredev- opment processes can use the example models presented in this special issue to understand the potential bene?ts of using AOM techniques at di?erent phases of the software development life-cycle.

The focus of the journal is on approaches for systematic identification, modularization, representation, and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems. This volume, the 12th in the Transactions on Aspect-Oriented Software Development series, contains one regular paper, on modular reasoning in aspect-oriented languages from a substitution perspective, and four extended, improved papers selected from those presented at Modularity 2014. Topics covered include novel dynamic semantics through delegation proxies, modularity potential detection based on co-change clusters, improvements in reusability for components of semantic specifications of programming languages, and probabilistic model checking applied to dynamically generated members of a product line.

This volume, the 8th in the Transactions on Aspect-Oriented Software Development series, contains two regular submissions and a special section, consisting of five papers, on the industrial applications of aspect technology. The regular papers describe a framework for constructing aspect weavers, and patterns for reusable aspects. The special section begins with an invited contribution on how AspectJ is making its way from an exciting new hype topic to a valuable technology in enterprise computing. The remaining four papers each cover different industrial applications of aspect technology, which include a telecommunication platform, a framework for embedding user assistance in independently developed applications, a platform for digital publishing, and a framework for program code analysis and manipulation.

Publisher description: "The LNCS Journal on Transactions on Aspect-Oriented Software Development is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus of the journal is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects, evaluation of such approaches and their impact on improving quality attributes of software systems. This book, the first volume in the Transactions on Aspect-Oriented Software Development series, presents nine revised papers that have been through a careful peer reviewing process by the journal's Editorial Board. The papers cover a wide range of topics from software design to implementation of aspect-oriented languages. The first four articles address various issues of aspect-oriented modeling at the design level; the following four articles discuss various programming language issues. The final article in this volume describes a workbench for implementing aspect-oriented languages, so that easy experimentation with new language features and implementation techniques are possible."
