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.”

• Policy driven software • Driven by metadata• Extends across entire zone
“make a duplicate copy of file upon initial store in this resource”

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

Extension of Test
05/28/2009 Texas Conference on Digital Libraries
12
• Add Texas Tech• Develop rules and policies• Extend metadata to include custom defined
elements• Test additional zones

How we use System
05/28/2009 Texas Conference on Digital Libraries
14
• 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

Open Repositories ‘09
05/28/2009 Texas Conference on Digital Libraries
15
• 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

Roadmap
05/28/2009 Texas Conference on Digital Libraries
16
• 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
