             Summary: Equivalence of NavigationProperty and Singleton or EntitySet
                 Key: ODATA-1184
                 URL: https://issues.oasis-open.org/browse/ODATA-1184
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: New Feature
          Components: CSDL JSON , CSDL XML
    Affects Versions: V4.01_CSD02
         Environment: Service document modeling
            Reporter: George Ericson


A Service often needs to provide additional data, such as service name, organization, model version, ....  This can be defined in an entity type referenced by a Singleton in the service document, but there really is no need to define a separate type for this purpose or for the additional complexity.

Currently the Service document (EntityContainer) is restricted to two specially defined property types.  Singleton and EntitySet. Assuming null for Singleton is allowed, ODATA-1183, the functionality of these types is equivalent to functionality provided by containment Navigation Properties.
