Asserting concrete values in subclasses (is_class_field?)

[Natureshadow]

Given the following model fragment:

classes:
  Credential:
    attributes:
      id:
        identifier: true
      description:
        required: true
        description:
          A human-readable description of this credential class
  Factor:
    attributes:
      id:
        identifier: true
      description:
        description:
          A human-readable description of this factor
      credentials:
        multivalued: true
        description:
          The credential classes this factor fulfills
        range: Credentia

I will later subclass Factor, to make, e.g., a FooFactor. FooFactor shall define a concrete set of values for the credentials slot, which all instances of FooFactor will get.

How could I model this?

I found the is_class_field attribute, which reads as if it should do what I want, but I am still missing the part of the puzzle where I provide the concrete values to assert from FooFactor on its instances.

If it helps, I could make the credentials slot point to an enum instead.

Hi @Natureshadow - thanks for the discussion topic! I believe the is_class_field is an internal LinkML slot we want to deprecate.

Can I clarify your question? Will the "concrete set of values for credentials in FooFactor" be ids?

Hi,

Can I clarify your question? Will the "concrete set of values for `credentials` in FooFactor" be `id`s?

Yes. Cheers, Nik
