 ## Import Sessions
 
-Import sessions are stored in `ZGENERICALBUM` with 'ZKIND = 1506`.  When a photo is imported, the value ZGENERICASSET.ZIMPORTSESSION is set to the primary key of the corresponding import album in `ZGENERICALBUM`. `ZIMPORTSESSION` may be `null` meaning there is no associated import session.

 In Photos 5, the import order is stored in a similar manner as the discussion above on album sort order.  The value in `ZGENERICASSET.Z_FOK_IMPORTSESSION` defines the sort order for an import session.  In Photos 6, `ZGENERICASSET` is renamed `ZASSET` and it no longer contains the the `Z_FOK_IMPORTSESSION` column.  I've not yet determined how Photos 6 stores the import order.
