We are unable to find properties mentioned in description, into the bulk download file from: https://openlibrary.org/developers/dumps

Hi @hornc,
In the link https://openlibrary.org/type/edition, I found 'copyright_date', 'uris[]', 'description' in the properties column. I want to access these columns, and so I downloaded 'editions dump' from https://openlibrary.org/developers/dumps. But in the downloaded data, these columns are not available. Kindly guide me on where I can find these required columns.
