ERA Vision
ERA will be a comprehensive, systematic, and dynamic means of
preservingpreserving and providing continuing accesscontinuing access
to any typeany type of electronic record free from dependencefree from dependence
on any specific hardware or software, created anywherecreated anywhere in the Federal Government.
National Archives and Records AdministrationElectronic Records Archives (ERA) Program
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

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

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

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)?

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?

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

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?
