             Summary: Clarify delta responses for deletions and containment or referential constraints
                 Key: ODATA-678
                 URL: https://tools.oasis-open.org/issues/browse/ODATA-678
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: OData JSON Format, OData Protocol 
    Affects Versions: V4.0_OS
            Reporter: Ralf Handl
             Fix For: V4.0_ERRATA02


If an entity is deleted, related entities will be implicitly deleted if a navigation property specifies <OnDelete Action="Cascade" /> or ContainsTarget="true".

It is not explicitly specified if in this case the service has to include a deleted-entity object for each deleted entity in a delta response, or whether it is sufficient to notify clients of the deletion of the principal entity.

The JSON Format design goal of omitting everything from the payload that can be deduced from $metadata would indicate to just notifying the deletion of the principal entity.
