Looking at MGD_GRCm38-C57BL6J_public.json
My understanding is the DATS JSON-Schemas are defined here: https://github.com/biocaddie/WG3-MetadataSpecifications/tree/master/json-schemas
Is the intention that each json file uses some mix of schemas, or a single one?
I'm guessing the MGI file uses this one:
