Second Workshop on Reengineering towards Product Lines (R2PL 2006)

摘要

Today, software intensive systems are developed more and more using product line approaches. These approaches require the definition of a set of product line artifacts including the product line architecture that implicitly or explicitly specifies some degree of variability. This variability is used to instantiate concrete software product instances. A product line approach not only implies reuse of architecture-level design knowledge, it also facilitates reuse of implementation-level artefacts, such as source code and executable components. The use of software product lines can reduce the cost of developing new products significantly. In practice, software products are usually not developed from scratch. Software product lines are typically introduced following an evolutionary approach, and a product line architecture is defined based on an initial set of products. The scope of the product line is gradually extended by incorporating more existing and new products. Before extending a product line, its suitability for incorporating additional products needs to be evaluated along with the extent to which the new and existing products conform to the product line architecture. For companies adopting a product line approach for their software development, the problem remains; how to reuse as much as possible of the existing legacy development artefacts. This applies to both the definition of a product line architecture and specifications of concrete product instances based on (legacy) software development artefacts. In this workshop we discuss the use of reverse engineering and reengineering technology to solve the problems described above. This workshop is a continuation of the R2PL 2005 workshop [1, 2] which was co-located with the WICSA and WCRE conferences in Pittsburgh.
