any_of combined with array

[jkiviluo]

I was trying to get something like this to work:

Classes:
  Link:
    description: "Connects two nodes."
    attributes:
      efficiency:
        any_of:
          - range: float
            array:
              maximum_number_dimensions: 1
          - range: DirectionalValue

But linkml-validate does not accept array within any_of

It seems I can get around this by (EDIT: actually not, it passes linkml-validate, but fails when trying to gen-python. It is not correct to use slots in this way I suppose):

...
        any_of:
          - range: array_or_float
          - range: DirectionalValue
          
slots:
  array_or_float:
    range: float
    array:
      maximum_number_dimensions: 1

For anyone looking for syntax examples on this topic, here are some (but the examples do not cover this case):
https://github.com/linkml/linkml-model/blob/main/tests/input/examples/schema_definition-native-array-rgb.yaml

Also for the record, I believe this is equivalent (but not sufficient for me, as I will need more dimensions down the road):

Classes:
  Link:
    description: "Connects two nodes."
    attributes:
      efficiency:
        any_of:
          - range: float
          - range: float
            multivalued: true
          - range: DirectionalValue

gen-python doesn't support any_of at all, we are in the progress of making this more transparent..

Right, thanks. It would be great that the documentation was more explicit on what is supported. At least on the generator pages.

I have switched to using gen-pydantic, but even then I cannot get everything I need to work. I would also need labeled arrays and they are not yet supported as it says here: https://linkml.io/linkml/schemas/arrays.html. So, my solution for now is to just read what I need into Python using linkml-runtime yaml_loader and continue from there.
