What we assemble, and where it comes from

The records a utility already produces and the public databases that hold the rest of them, named. Half of this work is a utility's own paperwork, which is usually the harder and more valuable half.

Two halves, and the first is the one most descriptions of this work leave out. A utility’s own records are usually the harder and more valuable side: they are in a billing system nobody has queried in years, a folder of PDFs, and a spreadsheet one person maintains. Public data is the half that is merely tedious.

Named as documents rather than as systems throughout. Naming a system would promise a connector that does not exist.
