Ontology of systems and software engineering

Systems and software engineering have evolved in the last years in a process of consolidation of their specificities as engineering disciplines. This has resulted in research and inquiry on ontological and epistemological issues related to them. Due to the supporting nature of systems and software engineering with regards to other engineering disciplines, these aspects are also relevant to researchers and practitioners in other engineering domains. The contents of this issue provide a selection of research aimed at consolidating ontology of systems and software engineering as a useful and consistent body of knowledge.
