A solutiom is that 'id' is an immutable attribute. It is set by the
server in the following way:
* generated for POST request
* url of the request for PUT request
> 
> In general, for renderings where core attributes are rendered differently from others (id, source, target, etc), it is not specified how to deal with attributes being set twice.
A proposal would be to have all attributes, at least for JSON, rendered
as flat attributes, with full name:
{ 'occi.core.id': ...
  'occi.core.source': ...
 'occi.core.source.kind': ...
 'occi.infrastructure.network...':
}

> A suggestion will follow in a next e-mail. For me, the most important being to avoid ambiguities as to improve implementations interoperability.
