Four kinds of entry. A dataset is a documented table or layer. A decision is a dated act by a named body that accommodated a load — and it may not be published without saying who paid. A site is a place where a load or a supply sat. A gap is something that is not published at all.
Every entry names its sources with a locator, states the grain its source reports at, and carries a reliability tier. Click any entry for the full record, or fetch it as JSON.
