The CoRE set of protocols, in particular the CoAP protocol, is
defined in draft-ietf-core-coap in conjunction with a number of
specifications that are currently nearing completion. There are also
several dozen more individual Internet-Drafts in various states of
development, with various levels of WG review and interest.
Today, this is simply a bewildering array of documents. Beyond the
main four documents, it is hard to find relevant information and
assess the status of proposals. At the level of Internet-Drafts, the
IETF has only adoption as a WG document to assign status - too crude
an instrument to assess the level of development and standing for
anyone who does not follow the daily proceedings of the WG.
With a more long-term perspective, as additional drafts mature and
existing specifications enter various levels of spec maintenance, the
entirety of these specifications may become harder to understand,
pose specific implementation problems, or be simply inconsistent.
The present guide aims to provide a roadmap to these documents as
well as provide specific advice how to use these specifications in
combination. In certain cases, it may provide clarifications or even
corrections to the specifications referenced.
This guide is intended as a continued work-in-progress, i.e. a long-
lived Internet-Draft, to be updated whenever new information becomes
available and new consensus on how to handle issues is formed.
Similar to the ROHC implementation guide, RFC 4815, it might be
published as an RFC at some future time later in the acceptance curve
of the specifications.
This document does not describe a new protocol or attempt to set a
new standard of any kind - it mostly describes good practice in using
the existing specifications, but it may also document emerging
consensus where a correction needs to be made.
(TODO: The present version does not completely cover the new
Internet-Drafts submitted concurrently with it; it is to be updated
by the start of IETF88.)
