This document details the intermediate version of the Smartness Hub implementation. At this stage, the implementation of the Smartness Hub has been extended to the other pilots and, in an attempt to prepare the Knowledge Layer for providing a more rich representation of the information, the Knowledge Graph has been extended and more work on semantics has been done. A first SRI model has also been included.
User and grid services have also been updated since they were introduced in D4.1, as well as the Security & Privacy framework.
