CNI Project Briefing

December 5, 2005

NDIIPP Elements

Preservation Partners

Technical Architecture


Lead Institutions for the 8 Partnerships

  • California Digital Library: Web political content

  • Emory University: MetaArchive of Southern digital culture

  • UC Santa Barbara: NGDA Geospatial Data

  • NC State University: Geospatial Data

  • U of Maryland: business records

  • U of Michigan: DataPASS--Social science data

  • U of Illinois, OCLC, State & academic libraries, NCSA: State government publications, among other content

  • WNET/PBS: Digital television

    (red=represented in today’s panel)

Goals for the Partnerships

  • Identify/select/collect content; communicate strategies for doing so

  • Probe intellectual property issues

  • Collaborate broadly in developing a shared technical architecture

  • Study economic sustainability

  • Identify and share best practices

  • Learn how to build and incrementally improve a preservation network

Network of Networks

  • LC pleased to see interconnections between partners, other networks

  • Some examples:

    • Association of Research Libraries

    • Digital Library Federation

    • Coalition for Networked Information

    • UK Joint Information Systems Committee

Broad Categories of Challenges

  • Technical

  • Legal

  • Social

  • Economic

MetaArchive ProjectEmory Univ. & partners

  • Distributed preservation network of six institutions now deployed and functioning

  • Conspectus database (based on UKOLN RSLP and DCC) of all collections archived in the network of nodes

  • Now working on developing a long-term Cooperative to support our network

  • Negotiating many issues about organizational roles and responsibilities in such a Cooperative

  • Examining various organizational structures for the Cooperative, including unincorporated association for interim period of 1-2 years, and 501(c)(3) for subsequent long term; now drafting inter-institutional contracts

North Carolina Geospatial DataArchiving Project

Project Goals

  • Preservation of state and local geospatial data resources

  • Engaging existing spatial data infrastructure

    Emerging Challenges

  • Rethinking content: not just data--also cartographic representation and geospatial documents

  • Technical challenges: handling complex objects in a repository; spatial databases

  • Engaging the industry: making the case for historic and temporal data--gathering use cases

UCSB—Geospatial Data: NGDA Overview


  • Designed NGDA architecture; combination of new and available:

    • Storage subsystem (Isilon, Archivas)

    • Server to connect components and manage ingest

    • Existing ADL as interface for access and federation

    • Major challenge: Developing Geospatial Format Registry

  • Collections issues in archiving geospatial imagery:

    • Developing collection policies and provider contracts

    • Definition of “at-risk” digital information

    • Identifying good collections to test/prototype system:

      • UCSB: 3 TB CaSIL data; Stanford: .5 TB, Rumsey Collection

    • Major challenge: Multi-layered data environment and poorly documented formats

  • Team building challenges:

    • People who understand mission and have technical skills

    • Developing a common vocabulary

  • Year Two goals:

    • Web-accessible prototype for demonstration

    • Economic sustainability models

    • Collections (MODIS, Landsat, Shapefiles, DOQQ)

ECHODepository: Illinois, OCLC, State & Academic Libraries, NCSA

  • Year 1 Accomplishments:

    • Selection rationale (Arizona Model)

    • OCLC Web Archiving Workbench Tools

    • Repository evaluation

    • Repository interoperability: Hub & spoke model

    • Partnership building: NCSA, CDL, others

  • Challenges:

    • Scalability & flexibility of software & storage architectures

    • Import/export commonalities: METS

CDL: Web at RiskA Distributed Approach to Preserving our Nation’s Heritage

  • Project Goal: develop a web-archiving service to enable institutions to continue their historic collection, management, and preservation roles.

  • Collection Challenges: web-based events (Katrina)

    • The nature of events on the web

    • Technical and social issues

    • Selection, collection & classification

    • Balancing rights and acquisition needs

    • Understanding information retrieval

Michigan: Data Preservation Alliance for the Social Sciences (DataPASS)

  • Goals:

    • Build Partnership to Identify and preserve at-risk digital social science content

    • Successful creation of a database of content

  • What have we learned?

    • Identification/selection daunting

    • Technology challenging

    • Aided by social science metadata standards

    • Building a partnership very useful

Emerging Issues

  • Natural tension between collaboration and tradition of institution-specific approaches

  • Much interest in joint infrastructure, but developing shared services will take time

  • Existing preservation methods are being stretched

  • Balancing a focus on project goals while also considering lots of interesting ideas

Learning and Incremental Development

  • We need to get broad feedback and continue learning

  • Still no “silver bullet” solution to digital preservation

  • NDIIPP considering all viable approaches, working toward gradual development of decentralized, interoperable architecture

  • Our partners are modeling this approach
