Case study questions
Case Study Questions Infrastructure and the NASA Goddard Library

  • How can the Dublin Core and knowledge organization systems be used in a heterogeneous project-based environment that also needs to preserve consistency for federated searching?

  • How can knowledge organization systems link local digital repositories to organization-wide efforts?

  • What is the framework for supporting an environment where projects are continuously added, thereby changing the metadata and vocabulary needs?


Case 1 the nbii
Case #1: The NBII Infrastructure and the NASA Goddard Library

The NBII is an electronic gateway to biological data and information maintained by federal, state, and local government agencies; private sector organizations; and other partners around the nation and the world.

Case 2 nasa goddard library
Case #2: NASA Goddard Library Infrastructure and the NASA Goddard Library

  • In the post-Columbia era, concern about sharing lessons learned

  • But… over 150 projects in Goddard’s Projects Directory; approximately 30 more added each year

  • Different project library systems with different metadata schemes

  • Library’s Digital Asset System was developed to provide a metadata catalog and a single search interface

Lessons learned from case studies
Lessons Learned from Case Studies Infrastructure and the NASA Goddard Library

  • Metadata schemes and knowledge organization systems are necessary

    • Core metadata element set

    • Base taxonomy or controlled vocabulary

  • A framework for addressing the needs of individual projects or nodes

  • Tools for mapping

  • A “central” organization to sustain a culture of interoperability


Nbii s use of metadata
NBII’s Use of Metadata Infrastructure and the NASA Goddard Library

  • NBII has standardized on the Biological Data Profile extension to the FGDC standard

  • Use Dublin Core for web sites, documents and presentations

  • Regional, national and international partners may have their own metadata element sets

  • Need for collaboration with new partners in other disciplines who may already have their own element sets


Nbii s use of kos
NBII’s Use of KOS Infrastructure and the NASA Goddard Library

  • Biocomplexity Thesaurus

    • Web sites

    • Journal articles and other materials in the Biocomplexity Database

  • Integrated Taxonomic Information System (ITIS) used to control terms for biological organism names


Goddard s use of metadata
Goddard’s Use of Metadata Infrastructure and the NASA Goddard Library

  • Developed the Goddard Core Metadata Element Set based on qualified Dublin Core

  • Used to bring various digital objects together

  • Map from Project Library metadata to the Goddard Core

  • Expect to use Goddard Core with OAI in the future


Goddard s use of kos
Goddard’s Use of KOS Infrastructure and the NASA Goddard Library

  • Use the NASA-Wide Taxonomy

  • Add specific taxonomy for each project

  • Map the specific taxonomy to the NASA-Wide Taxonomy

  • Develop specific pick lists for some elements such as content type and audience

Lessons learned from case studies2
Lessons Learned from Case Studies Infrastructure and the NASA Goddard Library

  • Metadata schemes and knowledge organization systems are necessary

    • Core metadata element set

    • Base taxonomy or controlled vocabulary

  • A framework for addressing the needs of individual projects or nodes

  • Tools for mapping

  • A “central” organization to sustain a culture of interoperability


Mapping tools
Mapping Tools Infrastructure and the NASA Goddard Library

  • Metadata Registry considered key to mapping and organizing across multiple schemes

  • Based on ISO 11179 Data Dictionary standard

  • Maintain the metadata and KOSs separately but map for interoperability

  • XMDR Project (www.xmdr.org) will allow more semantics to be expressed within this structure

Supporting organizations
Supporting Organizations Infrastructure and the NASA Goddard Library

  • NBII has infrastructure nodes and HQ staff to support standards, vocabulary and metadata development and training

  • Goddard Library has a Digital Project Group, quarterly Metadata Review Group Meetings and partnerships with other centers, agencies and external projects
