This document proposes an approach called APPLE for identifying and modeling aspectual features in software product lines. APPLE enhances traditional feature-oriented domain analysis (FODA) by using formal concept analysis to detect aspectual feature relationships that crosscut multiple features. It then models these aspectual features and integrates them into an enhanced feature model. A case study tool is presented that automates parts of the APPLE process and applies it to an arcade game maker case study.
