SP has consistent procedures for allowable actions taken upon its AIPs, as specified in the Preservation Implementation Plan. SP AIPs can be replaced or reloaded at the request of the Provider, and their identifiers adjusted accordingly. AIPs are not deleted as a part of normal operations. Please see the TDR Script Diagram for detailed documentation of procedures occuring during ingest, as well as the URI & File Naming Plan for a description identifier adjustment.
If there are any problems during these procedures, an error message is sent to the loaders.
