Without dataProduct, lists the governed data products this organization publishes: what each one holds, who owns it, and how sensitive it is.

With dataProduct, returns that product's schema: its datasets, the available fields with their types and sensitivity, the business glossary its owner wrote, and what the underlying source can compute. Read this before requesting access, so you request the fields the application actually needs.

Either way you learn the kind of system behind a product (so you know, for example, which query capabilities a source supports) but never a host, a credential, a table name, or a connection string. Request access with springroll.connect.request_access; a data owner must approve it.
