As a result of a successful IETF 6LowApp BarBof in Hiroshima, IETF CORE (Constrained RESTful Environments) WG is now formed.
"The CoRE working group will define a framework for a limited class of applications: those that deal with the manipulation of simple resources on constrained networks. This includes applications to monitor simple sensors (e.g. temperature sensors, light switches, and power meters), to control actuators (e.g. light switches, heating controllers, and door locks), and to manage devices."
