Who Validates the Validators?
Given a fip:Metadata-schema and a validator for it, such as a sh:Validator or a JSON Schema, how do you determine that the validator is…valid? That it speaks the desired fip:Knowledge-representation-language, that it knows all the terms in a desired fip:Structured-vocabulary and checks their usage against a desired fip:Semantic-model? In other words, that it adheres to a doap:Specification?
I do not know. However, I suspect that it is more important to check output rather than input.
