Dynamic Feature Deployment and Composition for Dynamic Software Product Lines

We aim to tackle problems with feature interoperability in dynamic software product lines: a feature allows collaborations with other features not conceived when it is deployed. In this position paper, we propose a Dynamic Feature Deployment (DFD) idea, which is a model-driven approach to support seamless integration of new features and changes of product configuration at runtime. The approach is based on a feature-modelling technique that directly deals with flexibility of reusable software assets in software product line engineering. We also propose a Hybrid between Passive/Active Behaviours (Hy-PAB) architecture model to support two extreme sets of behaviours for DFD: an active coordinating behaviour that controls the interactions with other features, and a passive subordinating behaviour that allows other features to control their interactions with other features.
