Define how OPC UA type information is specified in WoT TDs #30

Open barnstee opened 6 months ago

barnstee commented 6 months ago

A UANodeSet or Namespace of an OPC UA Information Model can optionally be referenced in the WoT TD to define the OPC UA types to be used for the mapping, including structures. This needs to be brought to the W3C WoT working group.

Current proposal is something like this: "@context": [ "https://www.w3.org/2022/wot/td/v1.1", { "opcua": [ "http://opcfoundation.org/UA/PNEM/" ] } ],

"properties": { "VoltageL1-N": { "type": "number", "mapping:opcua:nodeId": "s=VoltageL-N", "mapping:opcua:type": "nsu=http://opcfoundation.org/UA/PNEM/;i=3005", "mapping:opcua:fieldPath": "A",

Agreement is to move this to the new OPC UA WoT-binding working group.

Also need a way to make this type information available via PubSub metadata messages.
