  2. I met a traveller from an antique land Who said:—Two vast and trunkless legs of stone Stand in the desert. Near them on the sand, Half sunk, a shatter'd visage lies, whose frown And wrinkled lip and sneer of cold command Tell that its sculptor well those passions read Which yet survive, stamp'd on these lifeless things, The hand that mock'd them and the heart that fed. And on the pedestal these words appear: "My name is Ozymandias, king of kings: Look on my works, ye mighty, and despair!" Nothing beside remains: round the decay Of that colossal wreck, boundless and bare, The lone and level sands stretch far away. 1818 P.B. Shelley

  3. Digital Preservation • Systematic management of digital works over an indefinite period of time • Processes and activities that ensure the continued access to works in digital formats • Requires ongoing attention--constant input of resources: effort, time, money

  4. Backups ≠ Digital Preservation • Backups are tactical measures • Make copies to restore originals after data loss event. • Typically stored in a single location • Often nearby • Collocated with the servers backed up • Backups address short-term data loss with minimal investment resources

  5. Digital Preservation is Strategic • Long-term, error-free storage and for the entire time span the information is required. • Realistically address issues in preserving information over time • Ongoing investment • Geographically dispersed set of secure caches • Multi-institutional collaboration • DDPN: Distributed Digital Preservation Network

  6. Distributed Digital Preservation Network • Secure • PLN: Private LOCKSS Network • Reduces the likelihood that any single cache will be compromised • Distributed Geographically • Reduces likelihood that loss of any single cache will lead to loss of the preserved information. • A single organization is unlikely to have the capability to operate several geographically dispersed and securely maintained servers. • Inter-institutional agreements will ensure commitment to act in concert over time.

  9. MetaArchive Cooperative • DDPN: 2004 – • Separate preservation from access • LOCKSS w/out public access • Bit-level • Sustained by membership fees, grants • Library of Congress (NDIIPP) awards, 2003- • Nonprofit corporation: charter, membership agreement, tech specs • A cooperative, not a vendor • Training and model for others

  10. LOCKSS • Traditional • Public network • Host • Coordinates • Technical support • Web interface to audit preservation status • MetaArchive (PLN) • Training • Coordination • Technical support • Web interfaces to audit preservation status • Documentation • Conspectus

  11. NDLTD/MetaArchive Alliance ETD Preservation Survey • Dec. 2007-April 2008 • 95 institutions responded • 80% have ETDs • 27% have a preservation plan • 92% interested in DDPN

  12. NDLTD Preservation Strategy: MetaArchive • Preliminaries • Join, training, installation • Collection readiness • Permission, manageable units, define path • Harvest/ingest/cache • Continual comparisons, repairs • Dark archive: distributed preservation

  13. MetaArchive Cooperative • 16 members: US, UK, Brazil • 150 collections • Metadata: collection level • Images, text files, multimedia files, datasets, program executables

  14. MetaArchive Membership Levels • Preservation Member Sites • Fundamental activity: network node server • Preserve their own and others ETDs • Sustaining Member Sites • Fundamental activity: preservation node • Steering Committee, leadership, and technical development

  15. Staff Roles at Member Institutions • Program Managers • Data Wranglers • Systems Administrators • Librarians/Archivists

  16. MetaArchive Ingest Process • Plugin: scripts describing rules and structure of archival units of collections to be preserved • Local staff write these install them in the network • At least 6 dispersed nodes in a DDPN ingest the archival units: Caching

  17. NDLTD Preservation Guidelineshttp://scholar.lib.vt.edu/theses/NDLD/NDLTDPreservationPlan200906.pdf • Hardware, software • Metadata: Conspectus Database of Collections • Organizing ETD collections—best practices and data wrangling • Institutional Workflow • Personnel • Training Opportunities • Documentation and Reports • Retrieving from the ETD Archive

  18. MetaArchive and ETD Preservation • Recovery: plan for it; don’t put off for another day • Separate issues: access and preservation • Collaboration: everybody works and everybody benefits
