The specification says, for “Creating Resources”, in case of a success:
The response MUST also include a document that contains the primary resource created.
Is it ok to return a resource identifier and not the full resource that was posted? I am trying to minimize the amount of data transferred over the wire here.
If YES: can it be specified more precisely in the spec?
If NO: what is the reasoning behind it and how do you address my concern of optimising resources usage by not returning the same data that was passed in?
