> In OPC UA terminology the "server" is typically the processor that sits closest to the actual device generating the data. The server then collects the data from that "sensor" and makes the data available to upstream OPC UA clients. The clients will then consume that data from the server. In a nutshell the server is the software that reads data from devices, sensors, files, etc and then makes that information available to the clients over the OPC communication protocol.
> MiNiFi has a natural advantage at this part since we already have a lot of implementations to grab local data. My thought is to make this server implementation as something like a "Controller Service" in our world. And then introduce a correlating something like "PutOPCUAServer" processor. The controller service could be defined at a global level and there could be more than one of them. From there flows could be developed using all of the processors that are available to MiNiFi. Once the user has acquired the data that they want they could make a relationship to that "PutOPCUAServer" processor which would have a reference to the desired OPCUAServer controller service. This would allow for the flowfile contents and attributes to be placed into the server and all connected upstream clients to receive those values.
