An Automated Framework for Variability Management of Service-Oriented Software Product Lines

Service Oriented Architecture (SOA) development practices typically lack a systematic framework for managing variability in service requirements and architectures. This paper addresses this gap by applying software product line (SPL) concepts to model SOA systems as service families. The approach is to model SOA variability with a multiple-view service model and a corresponding meta-model. We integrate SPL concepts of feature modeling and commonality/variability analysis with multiple service requirements and architectural views by using UML and the Service Oriented Architecture Modeling Language (SoaML). The paper describes an automated framework for service-oriented SPL engineering that allows modelers to design, deploy, and execute service-oriented SPLs.
