It is possible to delete authority records that are no longer needed. This can be done either as a manual action or via an ongoing automatic deletion.
Manual deletion of authority record
From an authority record's detail page it is possible to delete the record by clicking "Delete" at the bottom of the page.
In some cases it is not possible to delete the authority record. The reason will be shown when you attempt to delete the authority record, but it is typically because the record has some essential relations to other authority records that must be deleted first. For manifestations, they cannot be deleted if they have related materials, reservations, bookings and subscriptions or are part of a material selection list or an order.
Automatic deletion of authority record
It is possible to configure an automatic job that continuously deletes authority records. This is done by enabling the configuration "Automatic deletion of authority records (EDM cataloguing)" under "Admin > Advanced settings > Periodic jobs".
The automatic job only deletes authority records that do not have relations to other authority records. For manifestations, they must additionally not have holdings.
The configuration also specifies how many days must have passed since the authority record was created before the automatic deletion takes effect. This ensures that newly created authority records are not deleted before they have a chance to be put into use.
