JSON downloads carry a self-describing envelope with the license, attribution line, generation timestamp, row count and format version. CSV downloads contain a header row followed by the data. The format is formally described by JSON Schemas: sites.schema.json and reviews.schema.json. Field additions bump the minor version; renames or removals bump the major.
