How to add custom metadata to the Events generated by a Device Service ? ( Eg. Modbus Service )

[FabioBoarettiDosSantos]

Please,

Can I have some guidance how to include more METADATA to the event.
I`m working with the IRELAND version at moment. MODBUS GOLANG

{"apiVersion":"v2","requestId":"20c74da2-849d-4955-a1d4-7eaffdf74152","event":{"apiVersion":"v2","id":"299f4034-815e-4a29-b611-e4fd6181b6f4","deviceName":"DGS-SOUST","profileName":"DGS-EXT","sourceName":"ReadyStatusBit","origin":1675107969704251870,"readings":[{"id":"bc3b339b-29b2-45d2-9109-2c95ff7cd79a","origin":1675107969704251870,"deviceName":"DGS-SOUST","resourceName":"ReadyStatusBit","profileName":"DGS-EXT","valueType":"String","value":"READY"}]}}

Thank You So Much [ ]

Event contains a tags field for adding more additional information. You can add more information in the App Service level in the Ireland release. Device Service didn't support it.
https://docs.edgexfoundry.org/2.3/microservices/general/#event-tagging

We are developing EdgeX 3.0, and you can add tags information into the Device metadata, and it can be added to the Event by Device Service.

@cloudxxx8 Thank you so much for your inputs and to be working on that feature!
If you allow me a following question about it: in the deviceProfile there is a "tag" but I cannot see it been
pushed in the event or readings ( is it part of the edgex 3.0) . Is it disable / no-functional or I`m doing something wrong ?

Thank you so much !

ADD: . Optionally I will use Edgex 2.2.

The data type of tag was wrong, and we didn't really use it, so we removed it in 3.0. Please use tags in the future release.
Before 3.0, you need to implement your own logic in Device Service or App Service for the metadata you need.
