This is the hash key of the attributes which make up the composite key--- Viewobjectname, Instancesetname and Entityobjectname ---for the Instances resource and used to uniquely identify an instance of Instances. The client should not generate the hash key value. Instead, the client should query on the Instances collection resource with a filter on the primary key values in order to navigate to a specific instance of Instances.
For example: publicSectorInstances?q=Viewobjectname=<value1>;Instancesetname=<value2>;Entityobjectname=<value3>
