Set up example data

[caufieldjh]

Example data doesn't quite parse yet - when hitting the multivalued relevance_to_dgps slot, it hits a snag:

Traceback (most recent call last):
  File "/home/harry/standards-schemas/tests/test_data.py", line 20, in test_data

    return item in cls.__dict__
TypeError: unhashable type: 'list'

This could be due to the DGPs being modeled as an enum rather than specific entities, so there may be a solution involving inlining.

This slot definitely needs to be multivalued, though - and that seems to be the core of the error, as self.relevance_to_dgps = DataGeneratingProject(self.relevance_to_dgps) doesn't seem like it would allow for that.

removing the is_a to node property will fix, because node property is not multivalued

[caufieldjh]

Removing the is_a: node property here leads to the same TypeError: unhashable type: 'list' Possibly an issue with how the yaml_loader works, as linkml-validate is much more helpful, as long as it's told about the target class of the data:

linkml-validate -s src/standards_schemas/schema/standards_usecase_schema.yaml -C UseCase src/data/examples/UseCase.yaml

[caufieldjh]

DataSubstrate schema example doesn't validate yet because the schema doesn't accept a string as valid. The metadata_storage slot will need to accept something other than a URI.

(probably need to define with any_of and an enum; see https://linkml.io/linkml/schemas/advanced.html)

[caufieldjh]

The DataStandardOrTool example isn't validating because:

Unknown StandardsCollectionTag enumeration code: Data Model

It needs to be datamodel.

After that fix, the validation errors are:

Unknown argument: concerns data topic = ['STANDARDSDATATOPIC:4']
Unknown argument: has relevant organization = ['STANDARDSORGANIZATION:76']

(fixed)
