Create a LinkML Validator Service for DataFed Schema Support

New issue

No due date
•Last updated Mar 31, 2026

We would like to add the capability to accept LinkML Schemas, associate these schemas to data, and validate metadata against these schema.

Complete functionality looks like:

  • A user uploads a schema.
  • A user uploads data and its associated metadata, selecting a schema to align to while doing so.
  • DataFed validates the provided metadata and raises validation errors.

Implementation currently depends on:

  • Creation of an OpenAPI api schema that this validator (and future metadata validator services, if applicable) conform to.
  • Creation of the python server that aligns to this schema and can accept, syntax validate, and store schemas.

Better description forthcoming.
