Abstract : |
Virtually every non-trivial software system exhibits variability: the property that the set of features---characteristics of the system that are relevant to some stakeholder--- can be changed at certain points in the system's deployment lifecycle. Some features can be bound only at specific moments in the life-cycle, while some can be bound at several distinct moments (timeline variability). This leads to inconsistent configuration interfaces; variability decisions are generally made through different interfaces depending on the moment in the life-cycle. In this paper we propose to formalize variability into a feature model that takes timeline issues into account and to derive from such feature models configuration interfaces that abstract over the life-cycle. 1., |
