Flagging SIPs as Deleted when all IEs are deleted/purged
One of our institutions keeps track of the ingested SIPs in an external application. Here, it is currently not easily possible to trace SIPs for which all IEs have been deleted.
When deleting all IEs of a SIP in Permanent, the SIP itself cannot be found in a search in Permanent - however, the SIP itself is not flagged as deleted in the SIP Report and its status remains as "Permanent/Finsished" when querying for SIP Status via the API. External applications therefore can't easily see that the SIP actually doesn't exist anymore.
For external integrations it would be helpful to mark the SIP somehow when all IEs are deleted, e.g. show status as "FINISHED-ALL-IEs-DELETED".
