  1. Technical Issues of Connecting GeoData within and Between Governmental Agencies: Focus on NSF Research Data Cyndy Chandler Biological and Chemical Oceanography Data Management Office Woods Hole Oceanographic Institution GeoData 2014 ~ 18 June 2014 ~ NCAR Center Green Campus, Boulder, Colorado

  2. Scope: NSF GeoData • NSF funded, hypothesis-driven, ocean science research projects from • Division of Ocean Sciences (OCE) • OCE Biology and Chemistry • Division of Polar Programs (PLR) • Antarctic ResearchANT Antarctic Organisms and Ecosystems

  3. Connectivity Challenges • Goals: • linking content at distributed repositories • improved interoperability • Technical strategies/solutions: • metadata content standards • controlled vocabularies • Linked Data • Not just technical • cultural conditions, behaviors • research data lifecycle • “proposal to preservation”

  4. An example • A researcher reads a paper • We have already assumed they have found and are able to retrieve the paper http://www.pnas.org/content/111/22/8089.full Patrick Martin, Sonya T. Dyhrman, Michael W. Lomas, Nicole J. Poulton, and Benjamin A. S. Van Mooy (2014) “Accumulation and enhanced cycling of polyphosphate by Sargasso Sea plankton in response to low phosphorus” PNAS 2014 111 (22) 8089-8094; published ahead of print April 21, 2014, doi:10.1073/pnas.1321719111

  5. Example (cont’d) there is a data supplement DOI

  6. What do I Know? general knowledge • Publication: PNAS, has a DOI, has data suppl. • Person name (author): Benjamin Van Mooy • Dates of activity: 2010 and 2012 • Location keywords: Sargasso Sea • Cruise: on vessel Knorr • Data keywords: plankton, polyphosphate, lipid domain specific

  7. Research is a game of Connect the Dots • the dots are entities of information and data from distributed repositories

  8. Connect the Dots • Some catalogs or repositories are already connected making it easier to “connect the dots”

  9. Connect the Dots • Some catalogs (repositories) are already connected making it easier to “connect the dots” • Dot #3 is a piece of information held in common (e.g. cruise ID)

  10. Connect the Dots • Some catalogs or repositories are already connected

  11. Connect the Dots • Some catalogs or repositories are already connected

  12. Connect the Dots • Persistent identifiers • for publications(DOI) • for data (DOI) • for people (ORCID)

  13. Connect the Dots • metadata • negotiated, shared, common IDs • persistent IDs from authoritative sources • controlled vocabularieslocal terms mapped to community-wide terms identified by URIs

  14. Connect the Dots • metadata • negotiated, shared, common IDs • persistent IDs from authoritative sources • controlled vocabularies • semantic markup to provide context and establish relationships

  15. context matters Semantic Web technologies can help

  16. Connect the Dots • Technical strategies/solutions: • metadata … more metadata • standards-compliant metadata • globally unique persistent identifiers from authoritative sources • controlled vocabularies (local & community-wide) • semantic markup • Linked Data* • Support transition from human to machine clients *Linked Data: Bizer, Heath, Berners-Lee, 2009; 10.4018/jswis.2009081901

  17. Progress since 2011 What has made the difference? • Program manager involvement • Consequences for PIs for not making data available • Long-term commitment (funding, active engagement) • Changing expectations from originators • Marine ecosystem research requires access to many different kinds of data

  18. Progress since 2011 What has made the difference? Community organizations • NSF EarthCube: funding to establish partnerships with other data managers, computer scientists and geoscientists • ESIP: opportunity to work with people from other communities doing similar work • discussions focus on challenges, activities deliver results • RDA: global organization to foster data sharing • International efforts with a domain focus (e.g. ocean)

  19. Modern data Semantic Webinfrastructure requires Technologies involve (2013) inspired by
