Hi Andrea -- Good question! In a repository environment metadata records 
of various types can persist past the withdrawal of the resource itself 
(sort of like suppressed records for withdrawn items in an OPAC, 
right?). The PREMIS record itself wouldn't have to be withdrawn, just 
updated with a withdrawal / expungement action, ideally with an 
explanation of why it was withdrawn.  (In Fedora, this would result in 
an object with no attached resource objects but with one or more 
metadata datastreams.)

There's actually an example of a PREMIS withdrawal event in the LC 
PREMIS RDF ontology:
http://id.loc.gov/ontologies/premis.html#hasEventDetail

It's a non-actionable note, however, which may be problematic for 
reporting / statistics.

It would be good to have some agreement about the best way to record 
this kind of information in PREMIS, along with agreement about 
desirability of doing this, e.g., to preserve the "forensic integrity" 
of a trusted digital repository.

For various reasons we have the need to support 'expungements' where we delete a particular set of content and its metadata. We document other significant events in PREMIS metadata embedded in object descriptors, but after this action there won't be any metadata for this content to record the event.

Do any of you have a method for doing this or know of any used in other preservation repositories?
