Response for a created resource - can it contain a resource identifier only?

Hi,

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?

Thanks.

Is it ok to return a resource identifier and not the full resource that was posted?

I’d say YES, based on the following:
From TopLevel description

Primary data MUST be either: …

and from Creating Resources:

The response MUST also include a document that contains the primary resource created.

and

The response SHOULD include a Location header identifying the location of the newly created resource.

and from Resource Objects

A resource object MUST contain at least the following top-level members …

and

In addition, a resource object MAY contain any of these top-level members …

Great, thanks for the reply.
