    abstract =  {The existing Constrained Application Protocol (CoAP) PUT method only allows a complete replacement of a resource. This does not permit applications to perform partial resource modifications. In case of resources with larger or complex data, or in situations where a resource continuity is required, replacing a resource is not an option. Several applications using CoAP will need to perform partial resource modifications. This proposal adds a new CoAP method, PATCH, to modify an existing CoAP resource partially.},
