System of systems information interoperability using a linked dataspace

System of Systems pose significant technical challenges in terms of information interoperability that require overcoming conceptual barriers (both syntax and semantic) and technological barriers. This paper presents an approach to System of Systems information interoperability based on the Dataspace data management abstraction and the Linked Data approach to sharing information on the web. The paper describes the fundamentals of the approach and demonstrates the concept with a System of Systems for enterprise energy management.
