American Numismatic Society
The American Numismatic Society retired FileMaker Pro in 2025 after two decades, migrating to the open-source CollectiveAccess. Its records had originated in a bespoke 1980s DOS system called PRIME before being ported into FileMaker, leaving a legacy of uncontrolled free-text fields. Moving to CollectiveAccess let the ANS reconcile that data as Linked Open Data, linking records to authorities such as Nomisma.org so that coins, mints and findspots could be collocated and mapped.
