The sanctions index now covers four official lists, each downloaded from the authority that publishes it rather than from any intermediary.
Together they hold tens of thousands of designations: individuals, entities, vessels and aircraft, with the identifiers, programmes and listing dates as the publishers record them. The UK list alone arrives as a fifty-megabyte file, so the import was built to resume where it left off rather than assume it can finish in one pass.
The lists are re-checked on a schedule and never re-downloaded while the local copy is still current, which keeps the load on the publishers to what is actually needed.
