RE: [odata] [OASIS Issue Tracker] (ODATA-1483) Expand all containment navigation properties recursively

["Ericson, George" <George.Ericson@dell.com>]

I don't have an immediate need, but I can imagine that it might be useful in some cases.  
The base reason for the suggestion is 'future proofing'.

Actually I only want to expand the containment navigation properties, no ambiguity there.

Use case is "document-style" APIs, with containment defining what is part of a "document", starting from the root node.

Do you have a use case for expanding all non-containment navigation properties?

The proposal is proposed use of expand is ambiguous w.r.t. containment.
Could we use tokens: (+contained, +referenced) or ($contained, $referenced)?  These can be combined to get navigation properties.

Ralf Handl created ODATA-1483:
---------------------------------

             Summary: Expand all containment navigation properties recursively
                 Key: ODATA-1483
                 URL: https://urldefense.com/v3/__https://issues.oasis-open.org/browse/ODATA-1483__;!!LpKI!1ybd3VNmVZGibFyb9Qgo6nzCl-1U81eME9yCOPM7EQFSvB8cKoyKOetS5kHs9w5ufQ$ [issues[.]oasis-open[.]org]
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: URL Conventions
    Affects Versions: V4.01_OS
         Environment: Proposed
            Reporter: Ralf Handl
             Fix For: V4.02_WD01


Containment navigation properties are often used to model "structured documents" where each of the "parts" is identifiable within its "container".

The proposed new expand syntax allows convenient retrieval of complete documents without having to inspect {{$metadata}}.
