  1. Texas Digital LibraryServicesPreservation Network

  2. Overview • Mission and goals for project • Initial test configuration • Current status of project • Extension of test systems • Challenges and opportunities • Questions Texas Conference on Digital Libraries

  3. Objective From TDL Website … “The preservation of the digital assets stored in the Texas Digital Library is a fundamental concern to be addressed as part of all the TDL’s services. A robust preservation network is being designed to provide long-term storage of digital information, geographically distributed storage nodes, and migration of supported formats to preserve the ability to access materials into the future.” Texas Conference on Digital Libraries

  4. Preservation is not Backup Texas Conference on Digital Libraries

  5. Phase .5 Goals • Establish initial test bed with multiple sites • Explore iRODS as software platform • Test transfer of files to multiple resource locations • Test policy or rules driven configurations Texas Conference on Digital Libraries

  6. Topology • Built on LEARN • Simple, Single Zone UT Austin TDL Zone TAMU College Station Metadata Server and Rules Engine Rules Engine Texas Conference on Digital Libraries

  7. Software • iRODS • Rules engine • Metadata server • Windows Explorer client • Web Interface Texas Conference on Digital Libraries

  8. iRODS • Policy driven software • Driven by metadata • Extends across entire zone “make a duplicate copy of file upon initial store in this resource” Texas Conference on Digital Libraries

  9. Current Status • Test configuration operational • Austin to College Station • Rather small configuration at this time • Imported multiple files • Tested transfer of files • Replicated files between nodes Texas Conference on Digital Libraries

  10. User Interface • Command Line Interface • Web browser • Windows Explorer • Developed in new software or added to existing systems Texas Conference on Digital Libraries

  11. User Interface Texas Conference on Digital Libraries

  12. Extension of Test • Add Texas Tech • Develop rules and policies • Extend metadata to include custom defined elements • Test additional zones Texas Conference on Digital Libraries

  13. Extension of System Rules Engine Texas Tech Lubbock UT Austin More Zones TAMU College Station Metadata Server and Rules Engine Rules Engine Texas Conference on Digital Libraries

  14. How we use System • Institutional Repository will be primary interface The IR will be the primary storage and search mechanism for scholarly works. • Little need to ever access iRODS servers directly Texas Conference on Digital Libraries

  15. Open Repositories ‘09 • Learned a great deal • Opportunities for collaborations • Study what others have done and are doing • UK and Europe strong leaders in preservation and archiving • Made a number of contacts Texas Conference on Digital Libraries

  16. Roadmap • Design configuration with geographically disperse nodes • Look at deep archive • Explore use of repository for archive management • Develop and refine policies for storage, retention, data migration • More fully develop metadata Texas Conference on Digital Libraries
