1. Always represent references in responses as <metadata:ref> or {"odata.ref":...} . 2. Allow passing entity references in {"odata.ref":...} and KEY(...) notation instead of entities to function and action parameters. 3. Remove edm:ReferenceType element and Ref(...)notation from CSDL. We don't need it anymore for passing parameters, and we want to give the client the choice of appending /$ref if it wants to save bandwidth. Returning only references and requiring additional requests for getting at the representations actually wastes bandwidth. 4. Keep KEY(...) notation in URL Conventions for use case E. 5. Rename odata.entityRef to odata.ref throughout For details see https://www.oasis-open.org/committees/download.php/48465/Representing%20Entity%20References%202013-03-05.doc Accepted: https://www.oasis-open.org/committees/download.php/48549/odata-meeting-29_on-20130314-minutes.html#odata-68
