A Taxonomy of Variability in Web Service Flows

The combination of Software Product Lines (SPL) and Service-Oriented Architectures (SOA) development practices is expected to become a new development paradigm maximizing reuse and business integration. However, multiples issues must be still addressed in order to clarify the connections between both fields. One of the key questions to answer is how SPL practices can be used to support serviceoriented applications. in this context, identifying and managing the points of variability in composite Web services emerges as an inevitable step for making possible such integration. in this position paper we give a first step toward such direction by introducing a comprehensible overview of the main variability points in Web service flows.Ministerio de Educación y Ciencia TIN2006-0047
