The overall methodology of EDDIE is oriented towards providing a dependable, scalable and extensible European Distributed Data Infrastructure for Energy Framework (EDDIE Framework). This means that the overlying European interface will be given priority, and data accessible through data-sharing infrastructure provided by metered data administrators will be available first. In parallel, and independently yet synchronised, the work on the second main objective to provide an Administrative Interface for In-house Data Access (AIIDA) to feed in-house data (2) to EDDIE Framework users will be started.
