Hi Achim, I did a quick check of the types mentioned in issue 1078. Not all of these are currently registered, although for most of these the number has been set to "Unassigned" in the Content-Formats IANA registry. So it looks like the sweep effort was not completed! In any case for a CoAP library it makes sense to * add support for the content formats (or a good selection of these? ) listed in the IANA Core Parameters Content-Formats registry. This is the definitive reference. * remove support for the types that are not registered in there. (Why would we squat on unassigned Content-Formats? People may get a false impression that these are the official content-format numbers.) - for some types the registration may be pending e.g. due to an I-D. These types can of course stay in the library code. However it may be hard to identify all such I-Ds ;) * the issue 1078 has the line: "Application/x-obix-binary = 51" -> this conflicts with the current assignment in the registry: application/json-patch+json (51). So it can better be updated to the registered type. So best to update it now; and create a new issue to check again in some future time whether new types were added in the meantime.

Is https://www.iana.org/assignments/core-parameters/core-parameters.xhtml#content-formats the consolidated result? best regards Achim Kraus _______________________________________________ core mailing list core@ietf.org https://www.ietf.org/mailman/listinfo/core
