Eclipse Milo


This project provides all the tools necessary to implement OPC Unified Architecture (UA) client and/or server functionality in any JVM-based project.

The project provides:

  • a stack implementation, compatible with the latest version (1.03) of the UA specifications.
  • a SDK built on the stack that enables development of compliant UA client and server applications.

The separation between stack and SDK may seem arbitrary at first, but the distinction is common within the OPC-UA community and vendors as it allows SDKs that serve different needs to be built upon a common stack.
