    • Type: Improvement
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: V4.01_CS02

      Add preference return=delta for PATCH requests. The server then may respond with a delta payload containing the changes to the server state identified by the ETag in the PATCH request.

      It is a preference, so servers can ignore it.

      The maximum shape of the delta can be specified via $select and $expand.

      Add boolean property DeltaResponseSupported to type Capabilities.UpdateRestrictionsType to advertise support for this feature.

      Description

      Update requests can have side-effects, e.g. changing the street of an address could as a side-effect also change the zip code even if it is not present in the PATCH request body.

      We need a way to communicate to the client what actually has changed.
