  1. Preserving and Sharing Digital Data • Greg Colati, Director, Archives and Special Collections • May 11, 2012

  2. The Problem with Digital Assets • Silos • Separate technical systems, metadata, and organizational schemes • Difficult to repurpose or share • Duplication • Same data in different systems out of synchronization • Duplicative but not redundant storage • Risk: • No accurate way to understand and manage the scope and volume of digital assets • No way to insure long-term availability

  3. How Do We Manage Digital Assets? Digital curation in a managed environment http://www.dcc.ac.uk/resources/curation-lifecycle-model 3

  4. How Do We Share Digital Assets? • EASY is not an attribute! • Multiple audiences, casual to serious • Multiple interests • Multiple levels of sophistication • Multiple needs • No ONE delivery system can provide for all potential uses

  5. What We Didn’t Want: • An “integrated” solution • Another information silo 8

  6. What We Needed: A Flexible Digital Repository Service • Preservation-oriented, trustworthydigital repository • Centrally managed • Supports long term management of digital assets • Set of services that support current and future needs • Open APIs for local development • Management tools • Presentation tools

  7. Repository Attributes • Simple and complex digital objects and relationships • Schema agnostic: any metadata schema allowed • File format agnostic: any file types allowed • Normalization for all metadata and supported content file types • Global, persistent identifiers • Rules-based access and management • Flexible presentation options

  8. What We Needed… • Independent, self-describing objects existing in a managed system with • No particular administrative workflow or end-user application • No particular catalog or organizational model

  9. What We Chose Flexible Extensible Digital Object Repository Architecture (Fedora) http://fedoracommons.org/

  10. What Fedora is Not • NOT a relational database • NOT a software application • NOT an integrated solution • NOT an information silo 6

  11. Fedora is… • A generic foundation upon which many kinds of applications can be created. • A conceptual framework about digital information and relationships

  12. Repository-based Activities Information Universe Re-use and exchange Metadata Digital Objects Presentation (Access) Layer Access, Discovery, Authentication, Authorization Management Layer CurationActivities; Administrative, Descriptive, Technical, Rights, etc., Metadata Mgmt. Repository (Preservation) Layer Policies, Controls, Preservation Activities Fedora

  13. Current Project Calendar • Phase I: Establish and implement core functions (July, 2012) • Phase II: Advanced tools and services, develop storage and hardware requirements for production system (January, 2013) • Phase III: Implementation of v1.0 production release for UConn content. (July, 2013)

  14. Extending the Model:A Statewide Repository Service

  15. Repository Organization

  16. Partner Framework Information Universe External aggregators and direct links Re-use and exchange Metadata Digital Objects UConn Partner Others… Presentation (Access) Layer Management: Partner Management: Others Management: UConn Management Layer Repository (Preservation) Layer Policies, Controls, Preservation Activities UConn Repository

  17. Durable Content, Shareable Data

  18. Sustainability Model (In Development) Pay for Services/Storage …Cost-recovery on an as-yet-to-be-determined model. Potential approaches include: • Membership ($/year based on a formula) • Subscription ($/GB/year) • POSF (Pay Once Store Forever) Other approaches or a combination of approaches are possible.

  19. Governance Model (In Development) …Volunteer your time • Advisory Committee made up of participating organizations • Reviews development plan for infrastructure and services • Suggests funding opportunities • Creates working groups for specific areas and tasks • SLAs created between the repository and UConn units document rights and responsibilities. • MOUs created between UConn and participating organizations document ownership, rights, and responsibilities.

  20. Challenges Ahead • Secure development funding for statewide services • Find partner institutions • Current partners include: • UConn • State Library • State Data Center (MAGIC) • Connecticut History Online (CHO) • Develop a sustainable governance and funding model
