Build on it

One API, one assistant connection, one receipt standard, and the door measuring itself in public.

In plain words

register: an official list a public body publishes: licenses, recalls, parcels, exclusions
keeper: the public body that publishes a register
record: one entry from a register, as the keeper printed it
receipt: the file a record came from, its fingerprint, and the date it was read
door: the one address, API and assistant connection, that serves every record
corpus: every record of one kind the door holds

Refresh log

Every file the connector has read, in the order it read them. A changed hash means the register printed something new since its last read; an unchanged one means the file was read again and matched.
