Hi Jeff we also applied that approach for publishing data of Italian
Transportation Ministry (dati.mit.gov.it) using CKAN (currently in
production since 2016). As an example look at "Certified Airports" dataset
at http://dati.mit.gov.it/catalog/dataset/aeroporti-certificati

We uploaded a JSON resource to store column metadata and linked the CSV to
it. As per the standard, downloading the CSV you get the reference to the
JSON file in the Link response header.
