During the three decades since the invention of the first variability modeling approach [28],
there have been multiple attempts to introduce advanced variability modeling capabilities …

Software product lines represent perhaps the most exciting paradigm shift in software
development since the advent of high-level programming languages. Nowhere else in …

Variability modeling is essential for defining and managing the commonalities and
variabilities in software product lines. Numerous variability modeling approaches exist today …

Knowledge-based Configuration incorporates knowledge representation formalisms to
capture complex product models and reasoning methods to provide intelligent interactive …

Abstract Context: Software product lines (SPLs) have reached a considerable level of
adoption in the software industry, having demonstrated their cost-effectiveness for …

The variability of a product line is typically defined in models. However, many existing
variability modeling approaches are rigid and don't allow sufficient domain-specific …

Feature diagrams are a popular means for documenting variability in software product line
engineering. When examining feature diagrams in the literature and from industry, we …

We present Clafer (cla ss, fe ature, r eference), a class modeling language with first-class
support for feature modeling. We designed Clafer as a concise notation for meta-models …

We present Clafer, a meta-modeling language with first-class support for feature modeling.
We designed Clafer as a concise notation for meta-models, feature models, mixtures of meta …

The scale and complexity of product lines means that it is practically infeasible to develop a
single model of the entire system, regardless of the languages or notations used. The …
