If a handle gets deleted sets the resource_id to null and keep all the other
information (basically resource_type and the handle itself). If something with
an handle is getting restored from an AIP backup, DSpace checks whether the
resource_type_id of the handle in the database is the same as of the
DSpaceObject being restored from AIP. Handles are Persistent Identifier. Nobody
wants a persistent identifier to change, because then it wouldn't be persistent
anymore. ;-) That is the reason DSpace ensures that at least the resource_type
of a deleted and restored handle doesn't change. I won't delete them as they
don't disturbe you and as it is wanted behavior.

Subject: [Dspace-tech] HANDLE table entries without resource_id
the query
SELECT HANDLE_ID, RESOURCE_TYPE_ID, RESOURCE_ID, HANDLE FROM HANDLE WHERE
RESOURCE_ID IS NULL;
finds a couple entries
Is there a reason why I should not delete them ?
