Software Clone Management Towards Industrial Application (Dagstuhl Seminar 12071)

Authors: Rainer Koschke, Ira D. Baxter, Michael Conradt, and James R. Cordy

Published in: Dagstuhl Reports, Volume 2, Issue 2 (2012)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12071 ``Software Clone Management Towards Industrial Application''. Software clones are identical or similar pieces of code or design. A lot of research has been devoted to software clones. Unlike previous research, this seminar put a particular emphasis on industrial application of software clone management methods and tools and aimed at gathering concrete usage scenarios of clone management in industry, which will help to identify new industrially relevant aspects in order to shape the future research. Talks were presented by industrial participants and working groups were formed to discuss issues in clone detection, presentation, and refactoring. In addition we developed a unified conceptual model to capture clone information required to support a common notion of clone data and for interoperability to foster exchange of data among researchers and tools in practice. The main focus of current research is clones in source code -- therefore, we also looked into ways of extending our research to other types of software artifacts. Last but not least, we discussed how clone management activities may be integrated into the process of software development.

06301 Working Session Summary: Presentation and Visualization of Redundant Code

Authors: Andrew Walenstein, James R. Cordy, William S. Evans, Ahmed Hassan, Toshihiro Kamiya, Cory Kapser, and Ettore Merlo

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
This report summarizes the proceedings of a workshop discussion session presentation and visualization of aspects relating to duplicated, copied, or cloned code. The main outcomes of the working session were: (a) a realization that two researchers had independently generated very similar methods for browsing and visualization clone "clusters," and (b) a list of questions for visualization, particularly in relation to how the "proximity" of clones may relate to interest in the clone.

Similarity in Programs

Authors: Andrew Walenstein, Mohammad El-Ramly, James R. Cordy, William S. Evans, Kiarash Mahdavi, Markus Pizka, Ganesan Ramalingam, and Jürgen Wolff von Gudenberg

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
An overview of the concept of program similarity is presented. It divides similarity into two types - syntactic and semantic - and provides a review of eight categories of methods that may be used to measure program similarity. A summary of some applications of these methods is included. The paper is intended to be a starting point for a more comprehensive analysis of the subject of similarity in programs, which is critical to understand if progress is to be made in fields such as clone detection.

05161 Executive Summary – Transformation Techniques in Software Engineering

Authors: James R. Cordy, Ralf Lämmel, and Andreas Winter

Published in: Dagstuhl Seminar Proceedings, Volume 5161, Transformation Techniques in Software Engineering (2006)

Abstract
TrafoDagstuhl brought together representatives of the research communities in re-engineering, XML processing, model-driven architecture and other areas of software engineering that involve grammar- or schema-driven transformations. These various existing fields and application contexts involve widely varying transformation techniques – the tradeoffs of which are worth analysing. This seminar initiated a process of understanding each other's transformation techniques – their use cases, corresponding methods, tool support, best practises, and open problems. This process makes it possible to exchange knowledge and experience between these various communities. This effort should also help in transposing transformation concepts from established application fields to new fields. This executive summary reports on the conception of the seminar, the program, outcomes and future work. Most of the material from the seminar (including abstracts of all talks) as well as additional papers can be found on the dedicated web site: http://www.dagstuhl.de/05161/

How to make a bridge between transformation and analysis technologies?

Authors: Jurgen Vinju and James R. Cordy

Published in: Dagstuhl Seminar Proceedings, Volume 5161, Transformation Techniques in Software Engineering (2006)

Abstract
At the Dagstuhl seminar on Transformation Techniques in Software Engineering we had an organized discussion on the intricacies of engineering practicle connections between software analysis and software transformation tools. This abstract summarizes it. This discussion contributes mainly by explicitly focussing on this subject from a general perspective, and providing a first sketch of a domain analysis. First we discuss the solution space in general, and then we compare the merits of two entirely di®erent designs: the monolithic versus the heterogeneous approach.
