D4.4 Whitebook on engagement towards interoperability in governance (V2)

This document summarizes the research and discussion of the int:net consortium with respect to energy interoperability aspects of administrative, political and industrial governance institutions. It introduces new elements for the Smart Grid Architecture Model (SGAM) which shall allow adding governance considerations to interoperability models and solutions, e.g. the "Tube in the Cube" concept and a proposal for a 6th layer, the framework layer. Additionally, it contains references to tools that int:net has developed to assess interoperability maturity and to move forward in practice with interoperability management in governing organizations, companies and associations.
