Building software product lines (SPLs) with features is a challenging task. Many SPL implementations support features with coarse granularity – e.g., the ability to add and wrap entire methods. However, fine-grained extensions, like adding a statement in the middle of a method, either require

Software product lines have numerous members. Thus, a product line infrastructure must cover various systems. This is the significant difference to usual software systems and the reason for additional requirements on the various assets present during software product line engineering

Programs of a software product line can be synthesized by composing modules that implement features. Besides high-level domain constraints that govern the compatibility of features, there are also low-level implementation constraints: a feature module can reference classes that are defined

Abstract. The software product line approach to the development of software intensive systems has been used by organizations to improve quality, increase productivity, and reduce cycle time. These gains require different approaches to a number of the practices in the development or

Model-driven software product lines combine the abstraction

In this paper, we discuss the notion of variability. We have experienced that this concept has so far been underdefined. Although, we have observed that variability techniques become increasingly important. A clear indication of this trend is the recent emergence of software product lines. Software

hundred have been reported in the literature, have serious limitations for many kinds of biological studies. Chief among these is the exclusion of their use for the production of human virus vaccines. This limitation is based on the supposition that such hetero-ploid cell lines, whether of normal

Although product line architectures serve an increasingly important role in the software development process, no representation currently exists in which they can be precisely captured. This position paper presents our work to date in addressing this problem. Specifically, we introduce a novel
