For now not all classes from object model have an identifier as a property. Objects of Placement class store their identifiers "placement_id" property, objects of Thing - in "metadata" dictionary as a value of "id" key and Connections don't have identifiers at all.
So, it's time to make some consistency in structure of all object model classes and to add an "domain_id" property
