CoRE provides a framework for resource-oriented applications intended to run on constrained IP networks. Such networks have limited packet sizes, may exhibit a high degree of packet loss, and may have a substantial number of devices that may be powered off at any point in time but periodically "wake up" for brief periods of time.

• 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.
