Proactively Assigning CoAP Content-Format Numbers to Registered Media Types
Klaus S. Hartke, Carsten Bormann · 2018
In order to use a media type with the Constrained Application Protocol (CoAP), a numeric identifier needs to be registered for it, the Content-Format number. RFC 7252 defines registration procedures for Content-Format numbers. The present document defines a proactive procedure to register a Content-Format number for many of the media types that are registered and discusses the benefits and limitations of that approach.
