Working session of the Darwin Core Germplasm extension and the GBIF IPT extension during the TDWG 2009 conference. Darwin Core (DwC) is a set of general terms applicable to most biodiversity datasets. The Germplasm extension extends the generic terms to include terms required for germplasm biodiversity datasets.

    • 1. GLOBAL BIODIVERSITY INFORMATION FACILITY TDWG 2009, Montpelier, November 12, 2009 Dag Endresen (NordGen) & Samy Gaiji (GBIF) WWW.GBIF.ORG DarwinCore Germplasm Extension and deployment in the GBIF infrastructure
    • 2. Topics for this session
      • Darwin Core (2009)
      • DwC Germplasm Extension (DRAFT 0.1)
      • Germplasm Extension Terms
      • Mapping to the Multi-Crop Passport Descriptors
      • Integrated Publishing Toolkit (IPT)
      • IPT Germplasm Extension
    • 3. Darwin Core (2009)
      • The Darwin Core should be viewed as an extension of the Dublin Core for biodiversity information.
      • The purpose of these terms is to facilitate data sharing
        • a well-defined standard core vocabulary
        • a flexible framework
        • to maximize re-usability
      • The Darwin Core can be extended by adding new terms to share additional information.
    • 4. DwC star schema
      • Star schema model
      • Can relate elements one-to-many
    • 5. DwC Germplasm Extension
      • DwC Germplasm Extension (DRAFT 0.1)
        • August 26, 2009
      • The DarwinCore Germplasm Extension
        • additional terms
        • to describe germplasm samples
        • maintained by genebanks worldwide
    • 6. DwC Germplasm Extension
      • DwC Germplasm Extension (DRAFT 0.1)
      • Modelled starting from the Multi-Crop Passport standard (MCPD, 2001)
      • Includes the new terms for crop trait experiments developed as part of the European EPGRIS3 project.
      • Includes a few additional terms for new international crop treaty regulations.
    • 7. DwC Germplasm (1)
    • 8. DwC Germplasm (2)
    • 9. DwC Germplasm (3)
    • 10. DwC Germplasm (4)
    • 11. DwC Germplasm (5)
    • 12. DwC Germplasm (6)
      • GermplasmDistribution
      • Perhaps add new terms to facilitate the reporting of germplasm distribution for the ITPGRFA (International Treaty for Genetic Resources for Food and Agriculture)
      • GermplasmManagement
      • The Millennium Seed Bank (Kew) has contributed feedback to the DwC-G modeling and proposed to include a number of seed management descriptors.
        • Seed processing terms
          • Seed cleaning
          • Seed germination testing
    • 13. Mapping of DwC-G terms to the MCPD descriptors
    • 14. Mapping of DwC-G terms to the MCPD descriptors (continued)

    • 16.  
    • 17. GBIF Informatics Suite
      • GBIF Decentralization Strategy (WP 2009-2010)
      • Customized biodiversity data networks
      • Tools to empower decentralized thematic or regional networks
    • 18. IPT
      • Project site:
      • IPT DEMO.
      • IPT LITE DEMO:
      • IPT Mailing List:
      • GBIF HIT:
      • GBRDS:
    • 19.
      • The GBIF IPT is an open source, Java (TM) based web application that connects and serves primary biodiversity data.
      • The data registered in the IPT is connected to the GBIF distributed network and made available for public access.
      • Designed to decentralize and speed up the process of indexing (large) biodiversity occurrence datasets.
      • IPT also provides a local tool for data quality assessment to data publishers.
    • 20. GBIF Integrated Publishing Toolkit (IPT)
        • Java 1.5 or higher is required
        • Apache Tomcat is recommended (1 GB RAM+)
        • GBIF IPT is provided as a WAR archive (for easy deployment)
        • GeoServer is included for web mapping (OGC Compliant, WFS, WMS, etc)
        • H2 Embedded Java Database (with JDBC interface and web console)
        • Hibernate (object relational mapping)
    • 21.
    • 22. IPT Interfaces
      • REST XML
      • TAPIR
      • DwC Archive
      • OGC (WFS, WMS, Web Mapping)
      • EML (Ecological Markup Language)
    • 23. Darwin Core Archive (DwC-A)
      • DwC-A publish dwc records including extensions
      • Simple text based format
      • Zipped single file archive Germplasm.txt
    • 24. The GBIF IPT service has a graphical interface to the datasets. Including a map, pie charts, or the right side context menu (taxonomy and geography).
    • 25. The IPT user interface includes the extensions
    • 26. XML interface includes the extensions
    • 27. GBIF IPT implements the Darwin Core Standard; and provides an interface to easily build extensions to the core Darwin Core terms. The draft germplasm extension is one example of how-to extend the Darwin Core terms for the GBIF IPT.
    • 28. Using GBIF technology (and contributing to its development), the PGR community can easily establish specific PGR networks without duplicating GBIF's work . The compatibility of data standards between PGR and biodiversity collections made it possible to integrate the worldwide germplasm collections into the biodiversity community (GBIF, TDWG).
