Ref

A Ref is a reference to some entity. When serializing an entity (e.g. a Process) that references another standalone entity (e.g. a Flow in an Exchange) we do not want to write the complete referenced entity into the serialized JSON object but just a reference. However, the reference contains some meta-data like name, category path etc. that are useful to display.
