Units

[kilojoules]

We are inconsistant or lacking in units documentation. It can be a child (units) or part of the description, or neither, in the current form

In the turbine schema we are doing pretty well and units is its own field

[kenloen]

To add units as an entry for a member, the Draft schema that we use needs to be extended with the option as it is done here: https://github.com/IEAWindTask37/windIO/blob/1a74473322c14a70296c13e5659bd6c68074b1ab/test/turbine/test_turbine.py#L75
At least if we are doing "strict" schema validation with additionalProperties: false which would be the best to ensure that the schema does not contain typos.

We should probably only add units as a possibility for entries of type: number

We should probably also add validation of the value (e.g. "kg", "m/s", "kg*m/", ..) units them self to ensure they are consistent and follow the same structure. I think this will be hard with a regex expression, but we could consider using a Python tool for it and extending the validator for this validation it: https://python-jsonschema.readthedocs.io/en/stable/creating
