def assign_rdf_subject

Otherwise the resource will have the id assigned by the LDP server
and assign_id can mint an id for the object, then assign it to the resource.
This is only used when creating a new record. If the object doesn't have an id 
def assign_rdf_subject
  @ldp_source = if !id && new_id = assign_id
    LdpResource.new(ActiveFedora.fedora.connection, self.class.id_to_uri(new_id), @resource)
  else
    LdpResource.new(ActiveFedora.fedora.connection, @ldp_source.subject, @resource, ActiveFedora.fedora.host + ActiveFedora.fedora.base_path)
  end
