Recovery of a reference architecture
Wolfgang Eixelsberger · 1998
1. ABSTRACT This paper presents experiences made while recovering the reference architecture of a system family. The case study is a subsystem of a train control system. The train control system is an embedded, real-time system that forms a family of systems. The architecture recovery approach and architectural representation is briefly described. The main topic of this position paper is the commonality analysis process that identifies and recovers the reference architecture of the system family. The two steps of the process are described together with implications. Since the recovery of the reference architecture facilitates the forward engineering process the mismatch between as-is-architecture and asshould-be-architecture is of special interest and described at the end of the paper. 1.1
