Has anyone heard of LinkML? It stands for Linked Data Modeling Language and the website is https://linkml.io

I heard about it at #community > Distribits 2024

Here is the unreleased schema DataLad is using: https://concepts.datalad.org/s/distribution/unreleased/

Michael Hanke showed me a few examples, including this from Resource:

# arbitrary well-defined properties can be attached to any
# Agent, Activity, or Entity
#
# Example: dataset on something heavy from Canada
id: exthisdsver:#
has_property:
  - type: obo:HSO_0000360
    name: origin country
    value: Canada
    is_defined_by: http://dbpedia.org/resource/Canada
  - meta_type: dldist:QuantitativeProperty
    type: obo:NCIT_C181733
    name: biospecimen weight (kg)
    value: "145.3"
    # kilogram
    unit: obo:UO_0000009
    range: xsd:decimal

And this:

      - id: exthisds:#s002
        name: s002
        has_property:
          # biological sex
          - type: obo:PATO_0000047
            value: male
            is_defined_by: obo:PATO_0000384

It's hard to explain, but it seems like a nice way to describe metadata.

Let me at least link to the section of his talk at https://www.youtube.com/live/BwRy3z_hQ70?si=RKJKhicMgjshoc6o&t=5631 where he starts talking about DataLad's metadata needs. Here's also a screenshot:
