Abstract

Similar to HTTP, the GET method defined in [RFC7252] for the Constrained Application Protocol (CoAP) only allows the specification of a URI and request parameters in CoAP options, not the transfer of a request payload detailing the request. This leads some applications to use POST where a cacheable, idempotent, safe request is actually desired.

 PATCH and FETCH Methods for the Constrained Application Protocol (CoAP)

Abstract

   The methods defined in RFC 7252 for the Constrained Application    Protocol (CoAP) only allow access to a complete resource, not to    parts of a resource.  In case of resources with larger or complex    data, or in situations where resource continuity is required,    replacing or requesting the whole resource is undesirable.  Several    applications using CoAP need to access parts of the resources.

   This specification defines the new CoAP methods, FETCH, PATCH, and    iPATCH, which are used to access and update parts of a resource.
