[OASIS Issue Tracker] (ODATA-479) Allow Content-ID referencing in request bodies for inserting links to newly created entities

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

     [ https://issues.oasis-open.org/browse/ODATA-479?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ralf Handl updated ODATA-479:
-----------------------------

    Proposal: 
Content-ID referencing in request bodies is allowed:

PUT $2/SingleValuedNavigationProperty
{
  "@odata.context": "http://host/service/$metadata#$ref";,
  "@odata.id": "$1"
}

POST SomeEntitySet
{
    ...,
    "SingleNavigationProperty@odata.bind":"$2",
    "MultiValuedNavigationProperty@odata.bind":["$1","$3","SomeEntitySet(42)"],
    ...
}


Servcies allowing $<content-id value> syntax in request bodies for inserting links SHOULD advertise this with the new term BatchContentIdReferencingInRequestBodiesSupported in the Capabilities vocabulary:

      <Term Name="BatchContentIdReferencingInRequestBodiesSupported" Type="Core.Tag" DefaultValue="true" AppliesTo="EntityContainer">
        <Annotation Term="Core.Description" String="Service supports Content-ID referencing in request bodies" />
      </Term>

  was:
Allow $<content-id value> syntax in request bodies for inserting links:

PUT $2/SingleValuedNavigationProperty
{
  "@odata.context": "http://host/service/$metadata#$ref";,
  "@odata.id": "$1"
}

POST SomeEntitySet
{
    ...,
    "SingleNavigationProperty@odata.bind":"$2",
    "MultiValuedNavigationProperty@odata.bind":["$1","$3","SomeEntitySet(42)"],
    ...
}
