Abstract

As AOSD is getting used in real-world applications, it becomes important to document the best practices that have repeatedly proven to work in practice. A first workshop on best practices in AO was held at AOSD 2006 which had the goal to mine best practices in using, building, extending, or integrating AOSD technologies. For AOSD 2007 we want to go one step further and collect patterns and pattern candidates. The goal is to start documenting AO patterns.

Workshop Topics

Todays software developers are faced with systems that must satisfy a broad range of concerns both from technical domains and business domains, while integrating a wide variety of systems and technologies. Conventional solutions to these challenges often result in code that is tangled, hard to read, and hard to maintain. Aspect-oriented software development (AOSD) overcomes this problem by enabling software developers to address each (crosscutting) concern on its own and then to compose the various concerns into a system. In recent years, AOSD has gained momentum and seen strong interest, both from the industry and academic research.

As AO concepts get mature and first industry strength languages and tools are available, the number of systems implemented in an AO language increases. AOSD concepts and technologies are getting mature and used in large, real-world applications. It becomes necessary to start documenting the best practices in applying AOSD to guide new developers and spread the experience beyond the AOSD community. The long term goal of this effort is to provide a mature foundation of AOSD best practices, similar to the best practices documented in software patterns on object-oriented software and related topics. Moreover, AOSD supports and integrates well with current industrial research topics such as model-driven software development, service oriented architectures and software product line engineering.

For this second workshop on Best Practices in Applying AOSD we solicit workshop submission in one of the following four categories:

Workshop Goals

The workshop has the goal to bring researchers and practitioners together, who have experience in using AOSD in real-world applications. It aims at the documentation of patterns for using AOSD, building or extending AOSD infrastructures, and using AOSD with other technologies, as well as real-world application examples from which patterns can be mined.

The patterns and pattern candidates can be reported wither in a well-known pattern format (such as the one used in the GOF or POSA books), but also in other suitable format, such as experience reports, case studies, reference architectures, reference models, etc. The goal is to share experiences, assess the state-of-the-art and the state-of-the practice, consolidate successful techniques, and identify the most promising application areas and open issues for future work.

Position Papers

Potential participants should submit a position paper of approximately 1-2 pages or a full paper of not more than 6 pages. Each paper will be reviewed by the organizing committee. Accepted contributions will be made available in advance over the Web and every participant is expected to read them before the workshop. The program committee will select contributions that ensure a lively discussion at the workshop, and render new collaborations after the workshop possible.

The workshop is planed as a full day event. The workshop will aim to foster discussion and interaction rather than elaborate presentations. After a short introduction by the organizers, all participants will be given a chance to briefly introduce their position or their case studies to provide triggers for discussion in the second part of the workshop by stating a controversial point of view, or by introducing a new point of view. In the afternoon, we will foster an open discussion using the "Open Space" technique. To give all workshop attendees sufficient opportunities for active participation, the discussion will take place in two to three groups in parallel. Each group will present their results to the larger audience before the closing discussion.

Submissions should be sent to: Iris.Groher@students.jku.at

The goal is to provide a traceability framework by making the relationships between requirements, the architecture and implementation artifacts explicit. Iris has gained experience in domain analysis and especially in feature modeling in different Siemens business units.
