[core] Removing entries from CoRE RD

[Alessandro Ludovici <[e-mail]>]

  

Dear List, 

I have a comment about the removal of RD entries
specified in section 5.5 of draft-shelby-core-resource-directory-04. 


The removal request interface defined by the draft is specified as
follows: 

 Method: DELETE 

 URI Template: /{+location}

At present,
the removal request has the effects of removing the whole registration
of an endpoint. However, an endpoint could have many resources
registered at the same location. If it wishes to remove only one or more
resources but maintains the remaining it can't.  

I propose to enrich
the removal request interface by allowing an endpoint to send the
removal parameter of one or multiple resource in CoRE Link Format. If a
removal request contains a payload in CoRE Link Format the RD will
remove only the resources that the payload specifies. Otherwise, the RD
will remove the whole registration of the endpoint. 

Regards,
