Patch Method for Constrained Application Protocol (CoAP)
Peter van der Stok, Anuj Sehgal · 2016
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 new CoAP methods, PATCH and iPATCH, to modify an existing CoAP resource partially.
