Full Exemplary PubSub Dataset

This folder contains a full PubSub dataset including topics and messages for data and metadata messages for the ShowcaseMachineTool of the umati SampleServer.

The data topic structure is mapped to files as follows opcua/umati/v3/json/data/verbose/server-cpp-dev/ShowcaseMachineTool/Identification → data_opcua_umati_v3_json_data_verbose_server-cpp-dev_ShowcaseMachineTool_Identification.

The metadata topic structure is mapped to files as follows opcua/umati/v3/json/metadata/verbose/server-cpp-dev/ShowcaseMachineTool/Identification → metadata_opcua_umati_v3_json_metadata_verbose_server-cpp-dev_ShowcaseMachineTool_Identification.json.

In this case we had the OPCUA-MQTT-Gateway umatiGateway configured with:

• clientId=verbose/server-cpp-dev in the umatiGatewayConfig.xml, which means
• COMPANY_ID=verbose
• PUBLISHER_ID=server-cpp-dev

Each file contains a json structured as follows:

{   
    // The topic, under which the message in "payload" is published
    "topic": "opcua/umati/v3/json/data/verbose/server-cpp-dev/ShowcaseMachineTool/Identification",
    // The message published under the topic
    "payload": { /* ... */ }

If one wanted to reproduce the message/topic tree, he simply would load all jsons metadata_* and data_*, iterate through them and send out messages containing the message in payload over the topic topic over mqtt. The filename itself does not need to be parsed in this case.
