Transcript of "NAGARA: SRB and iRODS"

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