    abstract =  {This document provides reference information for implementing a cross-protocol network proxy that performs translation from the HTTP protocol to CoAP (Constrained Application Protocol). This will enable a HTTP client to access resources on a CoAP server through the proxy. This document describes how a HTTP request is mapped to a CoAP request, and then how a CoAP response is mapped back to a HTTP response. This includes guidelines for status code, URI, and media type mappings, as well as additional interworking advice.},
