  1. TRLN Annual Meeting 2013 A Digital Preservation Repository for Duke University Libraries Jim Coble Digital Repository Services Duke University Libraries jim.coble@duke.edu

  2. TRLN Annual Meeting 2013 Preservation Repository • Improve digital asset preservation processes • First Use Case: Digital Collections Master Files • Digitized content, in-house and out-sourced • 380,000 archival master files (~ 20 TB) • Primarily still images, with some audio and video

  3. TRLN Annual Meeting 2013 Current Scenario (Typical) • Archival master files • Produced by library’s Digital Production Center (DPC) • Stored on filesystem • ACE-AM for periodic checksum validation • Descriptive metadata • Produced by Cataloging and Metadata Services department • Maintained in CONTENTdm (or elsewhere) • Technical metadata • Generated and maintained by DPC • Nothing ties these elements together except local knowledge and a DPC identifier

  4. TRLN Annual Meeting 2013 Initial Project Goal Archival Master Files Preservation Repository Descriptive Metadata DPC Technical Metadata

  5. TRLN Annual Meeting 2013 Technology • Fedora Commons Repository • Hydra Project Framework • Fedora (repository) • Solr (index) • Blacklight (discovery and access) • Hydra-Head (object creation / management)

  6. TRLN Annual Meeting 2013 Timeline • Spring 2012: Prototype using Fedora command line utilities and Django using “found time” • June 2012: Project formally launched • February 2013: Initial pilot completed • June 2013: Production preservation repository launched with two collections ingested

  7. TRLN Annual Meeting 2013 Ingest • Large amount of content to ingest • 380,000 archival master files (~ 20 TB) • Batch ingest mechanism • Reads content files from file system • Pulls in corresponding descriptive and technical metadata • Creates three PREMIS (Preservation) Event records for each ingested object • Ingestion • Ingest Validation • Initial Fixity Check

  9. TRLN Annual Meeting 2013 Export Sets • Delivering archival master files to authorized patrons upon request • Current process is manual • DPC staff locate master file(s) on filesystem • Possibly create a zip file • Place file(s) in pick-up location or copy onto CD, DVD, etc., for delivery

  10. TRLN Annual Meeting 2013 Export Sets • Built on bookmark functionality • Staff member searches for content-bearing objects of interest and bookmarks them • Export set can be created from bookmark list • Content files are retrieved from the repository and bundled into a zip file • Staff member can download and deliver to patron • Zip file includes a README manifest listing the content files with basic metadata
