1 A Community Approach to Preservation: Experiences with Social Science Data ASIST Summit 2010 Jonathan Crabtree April 9, 2010

2 The Odum Institute Oldest Institute or Center at UNC-CH Founded 1924 Mission: Teaching, research, & service for social sciences Cross-disciplinary focus

3 Odums Multidisciplinary Mission Diverse areas of study Culture of multidisciplinary collaboration Focus on data reuse History of data stewardship Successful at relationship building

4 Social Science Archives in Collaboration for Preservation Strategic partnership agreements Coordinated operations Joint best practices Shared federated catalog Shared tools & technologies

5 The Plan Identify significant data collections (classic) Identify important contemporary data (at risk) Develop common standards and procedures across partnership

6 Partnership Goals Use technological advances to encourage metadata standards and a shared catalog Establish a replicated storage network Develop common standards and activities Determine how the partnership can expand

7 Dataverse Network Open source platform OAI server DDI metadata standards Federated approach

8 Overview of How Catalog Works Access Data With Extraction and Analysis, Through Catalog Direct to Partner Sites View Information on Data Through Catalog Link to Data at Partner Site Search Shared Catalog Data Mirror Metadata Catalog Harvester Online Catalog Online Analysis

9 Multi-Archival: Syndicated Storage Platform

10 Dual Approach to Replication Private LOCKSS Network –Peer to Peer iRODS Datagrid –Client Server

11 Syndicated Storage Platform (SSP) Start with LOCKSS Lots of Copies Keep Stuff Safe But used in a closed network –Private LOCKSS Network (PLN) –A few of them out there MetaArchive perhaps the best known Biggest selling point was independence of each node in the PLN

12 iRODS extension of the NARA Transcontinental Persistent Archive Prototype (TPAP) OAI-PMH based transfer XML/XSL Translation iRODS rules and microservices

13 Nexuses for Preservation Failure Technical –Media failure: storage conditions, media characteristics –Format obsolescence –Preservation infrastructure software failure –Storage infrastructure software failure –Storage infrastructure hardware failure External Threats to Institutions –Third party attacks –Institutional funding –Change in legal regimes

14 Replication as Part of a Multi-Institutional Preservation and Sustainability Strategies There are potential single points of failure in both technology, organization and legal regimes: Diversify your portfolio: multiple software systems and hardware Find diverse partners – diverse business models, funding sources, and legal regimes Use strategic partnerships to achieve a balance Diversify your holdings Develop macro appraisal policies Develop data-transfer agreements that ensure sustainability

15 Summary Replication ameliorates institutional risks to preservation Data PASS requires policy based, auditable, asymmetric replication commitments Sustainability is attained through diversification Strategic partnerships must be made Data reuse is enhanced through macro appraisal policies
