oneM2M is an IoT server platform standard that supports devices as well as cloud server, while OCF(Open Connectivity Foundation) is an IoT service platform that supports devices. IPE(Interworking Proxy Entity) defined in oneM2M enables OCF devices to work with oneM2M server side platform.

• OCF IPE uses IoTivity source code as basis which is aligned with OCF standard. It is implemented in C++ and C.
• A gateway is requried to run IoTivity core and oneM2M device platform which is implemented in Java or Node.js.

This version of OCF IPE is working base on IoTivity 1.2.1. Other version of IoTivity that we did not test yet.
