These ten are fixed for the current release and shown in full: every attribute each facility carries, with one primary public source and the date it was read. Between them they populate all 13 of the 13 published attributes, and individually they carry 5 to 12 each — which is what the catalogue actually looks like. An attribute a source does not state is absent rather than printed as a blank.
Each facility carries one primary public source, the page that best identifies it, with the date it was read. That page may not state every attribute shown: a facility can have its power from an operator press release and its PUE from a sustainability report, and the pages behind each value stay in the internal source library. An absent attribute means no public source stated it — it does not mean zero, and it does not mean the facility lacks the thing.
The downloadable sample contains these same ten facilities and the public source columns, so you can test the file structure in your own spreadsheet or analysis workflow before requesting the full file. It is not the complete catalogue. The column-by-column reference is in the data dictionary, which also shows how often each attribute is populated across the whole catalogue.
