What a policy dataset can honestly carry
Primary-source records carry the document type - bill, rule, notice, hearing - its identifier, title, issuing body, the dates that matter at each stage, status and the source address, collected from the public bodies that publish them.
Stage dates are kept separately rather than collapsed into one date. A bill introduced, amended, passed by one chamber and signed has several dates, and a tracking product that keeps only one will mislead the people relying on it.
Where a client licenses Politico content, article records carry the headline, byline, section, publication timestamp and article identifier, within the licence's scope and with its reference on every row.
Citation records, built without the site, show where other outlets follow Politico reporting.
Every row carries the collection timestamp and its source type, so primary records and journalism are never mixed.
