Reference architectures refer to a special type of software architecture that captures the essence of the architectures of a collection of similar systems in a given domain, being an important support to the development, standardization, and evolution of software systems. In another perspective, variability makes it possible to easily change and adapt software systems for specific contexts in a preplanned manner. It has been considered in several research topics, including self-adaptive systems, large-scale enterprise systems, and system-of-systems, and was mainly consolidated by the Software Product Line area. Instead of advantages of handling variability, most reference architectures are built without containing such information and, consequently, considerable rework and costs have been necessary when systems built from these architectures need to be adapted. In this scenario, the main objective of this doctoral project is to establish a means to incorporate and manage variabilities in reference architectures. More specifically, a framework will be proposed containing methods to identify, represent, and validate variabilities in reference architectures, as well a method to instantiate these architectures. To evaluate this framework, case studies will be conducted by applying it a reference architecture built by the research group, in which this project take part. Moreover, surveys with specialists in reference architecture will complement this evaluation. As main results, we intend to contribute to become reference architectures more effective to instantiate new software systems.
