Architecture constraints for Interoperability and composability in a smart grid

This paper presents the Levels of Conceptual Interoperability Model (LCIM) in the context of supporting composability, interoperability, and integratability of systems and identifies the architecture constraints for enterprise and systems architectures. While enterprise architectures set the conceptual context for the systems, the system architecture defines the implementation details. These research results allow practitioners to identify which metadata are needed and where they can be stored. Current research on composability and research shows that these metadata are necessary, but not sufficient to support interoperability and composability in a smart grid. Some of the related challenges even have been proven to be undecidable.
