7. Sustainable Digital Data Preservation and Access Network Partners (DataNet)
2007 National Science Foundation Solicitation
$100 Million set aside for first phase
DataNet Goal: provide reliable digital preservation, access, integration, and analysis capabilities for science and/or engineering data over a decades-long timeline.

8. TerraPop Goals A framework for global-scale spatiotemporal data
Census microdata
Government land-use statistics
Land cover data from satellite imagery
Historical climate records (temperature, precipitation, cloud cover)

9. TerraPop Goals
Provide global-scale data on population, land use, land cover, and climate from the 19th century to the present
Interoperable across time and space
Accessible to researchers and the public

10. TerraPop Goals
Create a sustainable organization that can guarantee preservation and access over multiple decades
Organizational sustainability
Financial sustainability
Technological sustainability
Organization will be a collaboration with major data archives and universities and will eventually assume responsibility for IPUMS

12. Sustainability Organizational sustainability Financial sustainability
Technological sustainability

13. Organizational Sustainability
Hybrid approach:
University based like a library
International membership base ultimately responsible for governance

14. Financial Sustainability
University endowment ($1 million)
University will migrate technology “indefinitely, as long as it is needed”
Three archival partners contribute to preservation
Institutional member subscriptions
Grants and contracts

15. Technological Sustainability
Software and hardware continuously renewed
Virtualization/private cloud/evolvable cyberinfrastructure
Preservation standards (ICPSR, CIESIN, CESSDA/UKDA)

19. Three Formats of Integrated Data
Census microdata with attached characteristics describing land use, land cover, and climate for local areas
Aggregate data and for administrative districts with tabulated population data and environmental characteristics
Gridded data with characteristics of population and environment

20. Timeline September 2011: Funding begins
February 2013: Functional prototype
July 2015: Application for years 6-10

21. Reduced Scope 60% reduction in budget
Not a research project: Infrastructure project

22. Reduced Scope

24. Additions
Data inventory: Inventory and evaluate land-use, climate, and small-area census data for inclusion in the infrastructure.
Data acquisition: Collect and preserve selected datasets relating to population and the environment.
Boundary files: acquire or develop files, account for boundary changes
