[Fiware-iot] IoT and the IETF CoRE work - reference material

[Jan Höller]

Dear all,

As requested, below you find the list of most relevant work in the IETF CoRE WG. CoRE = Constrained RESTful Environments, i.e. how to take REST to tiny IoT devices.

IETF CoRE Charter: https://datatracker.ietf.org/wg/core/charter
This explains the purpose and scope of the CoRE working group.

Core CoAP: https://datatracker.ietf.org/doc/draft-ietf-core-coap/
This is the application level protocol running over UDP that realizes REST in constrained environments ("binary HTTP with simplified transport" for the layman)

Core Link: https://datatracker.ietf.org/doc/draft-ietf-core-link-format<https://datatracker.ietf.org/doc/draft-ietf-link-format>/
This document defines how to describe hosted resources and their attributes as well as discovery.

CoAP Interface: https://datatracker.ietf.org/doc/draft-shelby-core-interfaces/
This document defines well-known REST interface descriptions.

Resource Directory: https://datatracker.ietf.org/doc/draft-shelby-core-resource-directory/
This document describes a directory hosting descriptions of resources held on other servers. Cf the Fiware resource management.

Core Observation: https://datatracker.ietf.org/doc/draft-ietf-core-observe
This is a CoAP extension providing the capability to observe changes in the state of a resource.

HTTP-CoAP Proxy: https://datatracker.ietf.org/doc/draft-castellani-core-http-mapping/
This provides a base reference documentation for HTTP-CoAP proxy implementation.

I hope this helps.

As for the IoT gateway we have implemented, the above specifications is what we are using (and partly contributing to).
