Not included, and not licensed here: the photographs. They belong to the
businesses and platforms named in imageSourceUrl, or to the photographer named
in imageCredit, and are shown on the site with credit and a link back. This
export carries those facts about each photograph, never the file.

Names: submittedBy and imageCredit name people only where they asked to be
credited as the spotter or the photographer. If you keep the record, keep the
credit; if you cannot, drop the field.

Prices are as last seen, not live, and coverage follows one person's walking
radius; https://chirts.kanav.net/data describes the fields and the caveats.
