separating variability concerns in a product line re-engineering project
Feature diagrams have now become common variability models in software product lines engineering literature. Whereas ongoing research keeps improving their expressiveness, formalisation, and automation, open studies of their usage in real projects are still missing. This paper intends to (1) present the process we followed to elicit the variability of PloneMeeting, an Open Source project, and (2) report on the initial results obtained when applying variability modelling techniques promoting separation of concerns between software variability and product line variability.
