Deleting a Container with an HTTP DELETE method call MUST delete all its members. More precisely: for a container with URI Uc, let the set of its contents S, be all the results given by the query SELECT ?c WHERE { ?container a ldp:Container; rdfs:member ?c . } where ?container is bound to Uc. Then deleting the resource named by Uc should delete all the resources named in the set S . Furthermore deleting any resource ?r in the container ?c, such that ASK { ?c rdfs:member ?r } . MUST remove the element R from the container C.
