Large organizations usually have legacy systems that represent effort and resources invested, besides encompassing rich business knowledge. They frequently develop systems of the same domain, what has been motivating the migration to reuse approaches such as Domain Engineering (DE) and Product Line (PL). Within a certain domain, a reference architecture (DSSA) represents the basis for application instantiation. In this context, legacy systems are essential information sources for domain specification. Therefore, this paper presents an approach for legacy system architectures comparison to support the creation of DSSAs, which can be used in the context of DE and LP.
