Transcript

  • 1. Why SRB and iRODS The Case of the TPAP
  • 2. Building the Electronic Records Archives
    • ERA Vision
    • ERA will be a comprehensive, systematic, and dynamic means of preserving and providing continuing access
    • to any type of electronic record free from dependence
    • on any specific hardware or software, created anywhere in the Federal Government.
  • 3. Building the Electronic Records Archives
    • ERA Requirements
      • Scalability
        • 10 Trillion Digital Objects, 350 Petabytes
      • Evolvability
        • Change Components Without Disrupting the System
      • Extensibility
        • Deal with 4,000+ File Formats and Those Still to be Invented
      • Manageability
        • Must be able to Invoke NARA Policy with Changes Over Time
  • 4. Building the Electronic Records Archives
    • Beyond the Current State of the Art
    • ERA Research for Risk Mitigation
      • 50 Research Partnerships
      • World Class Computer Scientists and Engineers
      • White House Coordinated Research Activity
  • 5. TPAP
    • Transcontinental Persistent Archives Prototype (TPAP)
      • Testbed Used for Many Research Collaborations
      • 10 Years (Multiple Generations of Software)
      • Migrating from SRB to iRODS (Greater Policy Flexibility)
      • 7-node Data Grid
      • 10 M+ Unique Files
  • 6. Lessons Learned - Questions to Ask
    • Scalability
      • How Many Bytes Can the Software Manage?
      • How Many Digital Objects Can the Software Manage?
      • Will it Scale Down (e.g., Run on a Laptop)?
      • Will it Scale Up (e.g., Run on a Supercomputer)?
  • 7. Lessons Learned - Questions to Ask
    • Evolvability
      • How Do You Export the Data From the System?
      • How Many Generations of the Software Have They Migrated Records Across?
      • What Software Environments Does it Operate Across?
  • 8. Lessons Learned - Questions to Ask
    • Extensibility
      • Have the Developers Been Able to Extend the Software to Work Seamlessly with New:
        • File Formats
        • Operating Systems
        • Database Software
        • User Interfaces
  • 9. Lessons Learned - Questions to Ask
    • Manageability
      • What Archival/Records Management Policies Does the Software Support?
      • Can You Easily Customize the Software to Support Your Repository’s Policies?
