I was wondering if there is any standard or pseudo-standard when it comes to IoT configuration.

Is always something custom the correct solution here?

I want:

- Interoperability between Go (backend/cloud) and C (devices).

- Validation (Schema?).

- Versionable.

- Allow partial configuration updates.

- Declarative.

I took a look to CUE but I am not sure if it fits in this scenario.

Any ideas of experience on this field is welcome.

Thanks.
