3. 11/17/2010Indiana Library Federation 2010 - Jenn Riley3 What to preserve? Media? (some digital, some analog) Bits? Intellectual content? How to preserve it? Migration? Emulation? How does preservation relate to access? Not surprisingly, we’re learning that “it depends.”

4.  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 2010 - Jenn Riley

5.  OAIS = Open Archival Information System  “Reference Model” for an “organization of people and systems” to facilitate long term preservation of content  ISO 14721:2003  OAIS-compliant repositories meet preservation responsibilities as laid out in the reference model 11/17/20105Indiana Library Federation 2010 - Jenn Riley

7.  PREservation Metadata Implementation Strategies  Development began in 2003 under leadership of OCLC and (then) RLG  Data dictionary released 2005; revised 2008  LC is current maintenance agency 11/17/20107Indiana Library Federation 2010 - Jenn Riley

8. 2/7/2007Digital Library Brown Bag Series8  “The information a repository uses to support the digital preservation process”  Metadata that supports  viability  renderability  understandability  authenticity  identity  Mandatory elements represent “the minimum amount for [a] second repository to accept custody of [a] digital object and assume responsibility for its long-term preservation”

10.  Intellectual entities are the things we’re interested in  And can be groups of things  Objects are specific things a repository manages 11/17/2010Indiana Library Federation 2010 - Jenn Riley10 File Bitstream File Representation (of an intellectual entity)

18.  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 2010 - Jenn Riley18
