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: Dot.com 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
www.digitalpreservation.gov 5
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 Project Emory 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 ProjectProject Goals• Preservation of state and local geospatial data
resources• Engaging existing spatial data infrastructureEmerging 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 Overviewhttp://www.ngda.org

UCSB NGDA: FIRST YEAR PROGRESS AND ISSUES 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
www.digitalpreservation.gov 13
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
www.digitalpreservation.gov 14
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
www.digitalpreservation.gov 15
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
