gen-py-classes generating extra slot info

[wdduncan]

For reference see https://github.com/microbiomedata/nmdc-metadata/pull/139.

When running gen-py-classes on nmdc.yaml, we are getting extra slots of the form <x value>_has_raw value, <y value>_has_unit. For example:

slots.quantity_value_has_raw_value = Slot(uri=NMDC.has_raw_value, name="quantity value_has raw value", curie=NMDC.curie('has_raw_value'),
                      model_uri=NMDC.quantity_value_has_raw_value, domain=QuantityValue, range=Optional[str])
slots.quantity_value_has_unit = Slot(uri=NMDC.has_unit, name="quantity value_has unit", curie=NMDC.curie('has_unit'),
                      model_uri=NMDC.quantity_value_has_unit, domain=QuantityValue, range=Optional[str])

Is this behavior correct?

We may be able to close this in favor of the more general #231

it's not clear the existing python behavior is so bad. we don't have an easy mechanism for compound keys here, hence the manifestation of the induced primary key

Yes. Let's close in favor of #231.
