1. PeDALSPersistent Digital Archives & Library System Richard Pearce-Moses Deputy Director for Technology & Information Resources Arizona State Library, Archives and Public Records

2. Formerly known as BAGELSS Beginning an Aggregated Government E-Records and Library Service Solution

3. Project Partners and Supporters • Funding from • Library of Congress/NDIIPP • Institute of Museum and Library Services • Partners • Arizona • Florida • New York • South Carolina • Wisconsin • Kudos to the Washington State Archives

4. Concerns • Scale work to meet the growing number of digital publications and electronic records in time of limited resources • Ability to preserve those materials so that we could demonstrate authenticity and protect integrity

5. Technical Goals • To develop a curatorial rationale that can be implemented in software to support an automated, integrated workflow to process collections of digital publications and records

6. Curatorial Rationale • Transformation of traditional, paper-based practices into the digital arena • Appraisal • Acquisition • Arrangement and description • Housing and storage • Reference and access • Preservation

7. Curatorial Rationale • Logical, systematic basis for our work • Evolutionary (reactionary) v. Designed (intentional) • Integrate work done in different, narrowly defined areas • Focus on the rules, not the records • Automate the rules

8. Technical Goals • To develop a curatorial rationale that can be implemented in software to support an automated, integrated workflow to process collections of digital publications and images • To build “digital stacks” – storage that has appropriate controls for preservation and disaster preparedness

9. Digital Stacks More than storing the data (CD, tape, disk) LOCKSS • Automatic integrity checking and error correction • Secure • Geographically distributed

10. Additional Goals • To build a community of shared practice that meets the needs of a wide range of repositories • For best practices • For resource sharing • To remove barriers by keeping costs as low as possible

11. Assumptions • Consistency of government records makes it possible to simplify processing by focusing on common traits • Volume of records – especially at the series level – make it reasonable to automate processing

12. Consistency & Volume • Bride’s Name • Groom’s Name • Marriage Date • Recording Date • License Number • Office of Origin • Series name • Location (county) • OOO Identifier • Documentary form

13. Data Flow

14. Project Tasks • Design system (hardware, software) • Develop Curatorial Rationale • Identify core metadata • Descriptive standards (content, data values) • Functional specs for administration, discovery, preservation • Create Accessions Register database • Develop schemas for AIPs, SIPs, and DIPs • Implement rules in middleware • Create website for public access
