Hello.
Verifying the mappings created for the "Elementary operations on a site" 
[18] feature against the distributed glance specification [19], I can 
see a vital feature is missing for "Advanced operations on a site", like 
creating an image locally, when the parent control plane is not 
available. And consequences coming off that, like availability of create 
snapshots for Nova as well. All that boils down to a) better identifying 
the underlying requirement/limitations for CRUD operations available for 
middle edge sites in the Distributed Control Plane case. And b) the 
requirement of data replication and conflicts resolving tooling, which 
comes out, if we assume we want all CRUDs being always available for 
middle edge sites disregard of the parent edge's control plane state. So 
that is the missing and important thing to have socialised and noted for 
the mappings.
