2.1.23 Section 13 Entity Reference

The specification states the following:

 An entity reference (see [OData-Protocol]) MAY take the place of an entity instance in a JSON 
 payload, based on the client request.

OData in the specified Microsoft implementations (section 1.3) partially supports this feature. Entity references are not supported. Links are represented by using a name/value pair named "url", as shown in the following example:

 {
     "url": "http://host/service/Orders(10643)"
 }
