I have read that there might be some specification on the integration of OPC UA and DDS within "OPC Foundation's DDS OPC UA Part 14". Can somebody tell me how to find this specification or where it has been released? Through the website of the OPC Foundation, only Part 1 - 13 can be found... Thanks in advance!
OPCUA Part 14 is a new part that focuses on "Publish Subscribe". I think it is not finalized yet so it is only available to members of the OPC foundation.
There has been discussions within the OPCUA working group of making DDS one of the "Communications models" for OPCUA Pub-Sub. As far as I know the OPCUA working group has still not made a decision whether to go forward with this. If it is done then it may be included in OPCUA Part 14 or be defined in a separate document.
If you have an opinion or use-case for this I think this is a good time to voice it because it may very well influence what the OPCUA working group does.
