In function object.__get__(self, instance, owner), owner is always the owner class, while instance is the instance that the attribute was accessed through, or None when the attribute is accessed through the owner. Setting owner default value makes no sense. refer to: http://python-reference.readthedocs.org/en/latest/docs/dunderdsc/get.html#get Change-Id: I74c2105f3100711b62171db65bc0656393adf2b8
oslo.versionedobjects
The oslo.versionedobjects library provides a generic versioned object model that is RPC-friendly, with inbuilt serialization, field typing, and remotable method calls. It can be used to define a data model within a project independent of external APIs or database schema for the purposes of providing upgrade compatibility across distributed services.
