 Not a solved problem, but also not an unknown one  An active research area  Dependent on preservation metadata, but…  More about policy than technology 11/17/20104Indiana Library Federation Jenn Riley

 Nope. All this stuff represents a new approach to metadata creation.  Software that creates and manages digital file also creates technical, process history, preservation metadata about it  Maybe also by asking the user for some specific input  Management tools package together metadata and content for transfer and repository ingest  But to implement your preservation policies, you need to understand what metadata is being created, how it’s stored, and when. 11/17/2010Indiana Library Federation Jenn Riley18
