We are sharing some BQ datasets with a third party (outside our org) using analytics hub. So, the subscriber is able to create a linked dataset in their project and any queries they run are billed to their project.

I have a dataset and a table in google big query (BQ). For the dataset, I can add description, and for the table I can add description and column policy tags to control column level access (I am ignoring the “Labels” and “Tags” that one can attach to any BQ resource).
