Eclipse Milo

Milo is an open-source implementation of OPC UA. It includes a high-performance stack (channels, serialization, data structures, security) as well as client and server SDKs built on top of the stack.

While this project has existed for some time, it is new to the Eclipse foundation and is therefore considered to be in incubation. While in incubation it will continue to use 0.x.x versions.
