preserved

Preservation seen as an IT problem
Why Archives Know More:
Digital Preservation policies part of accreditation
More born digital material
More able to control archival formats
Confused vocabulary between IT and end-users (irn, mediakey, Multimedia/Media record)
Backups potentially offer false security
Assets can degrade spontaneously; through human error; on access / copy
Any errors must be detected within backup retention window
Do you see that as a part of DAMS or as a separate product?
Do you see that you will or do have a need for such a product?
When do you think your organisation will need to deal with this problem (if at all)?
