  1. DLESE and NSDL: Digital Library Components of Cyberinfrastructure International Workshop of Cyberinfrastructure for Geosciences IWCG2006 - Beijing, China July 21-23, 2006 John Weatherley University Corporation for Atmospheric Research (UCAR)

  2. I.M. Pei • NCAR Lab (UCAR, shown below) – Built 1967 • Fragrant Hills Hotel – Built 1982 “You just cannot compete with the scale of the Rockies. So we tried to make a building that was without the conventional scale you get from recognizable floor heights – as in those monolithic structures that still survive from the cliff-dwelling Indians.” – I.M. Pei

  3. Overview • NSDL and DLESE • Digital Library (DL) components of cyberinfrastructure • Knowledge representation in DLs • Example applications

  4. Digital Libraries: Overview • Discovery of educational resources, data sources, tools, visualizations, etc. • Resource and information sharing and reuse • Support learning and knowledge formation

  5. DLESE NSDL • 20,000+ discrete items • 20+ collections from ~15 institutions • To provide support and leadership to the Earth System community in addressing the national reform agenda for science education, scientific literacy • 1,000,000+ discrete items • 120+ projects in 74 institutions • Encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning

  6. NSDL Overview Funding Agency:National Science Foundation • Education and Human Resources Directorate • Initiated by NSF in 2000 as R&D project, now part of NSF’s educational cyberinfrastructure Scope:Education at all levels (K12, Higher Ed, Lifelong Learning, Research) • Science, Technology, Engineering, and Mathematics Structure:Distributed holdings and services, provided and maintained by many organizations • All joined by a “Core Integration” team, comprising University Corporation for Atmospheric Research – Kaye Howe Cornell University – Dean Krafft Columbia University – Kate Wittenberg

  7. NSDL Network College and K-12 Teachers 202 NSDL-funded Collections and Services University 9 NSDL Pathways: Discipline or Audience -Specific Portals Faculty Researchers Other NSF-funded Resource Providers National Visiting Committee External Resource Providers, including Publishers Librarians Informal Educators Digital Library Developers

  8. NSDL Pathways • Educational level and discipline specific views of NSDL • Built by leading organizations who are trusted by their target audiences • Provide resources, tools, services, and professional development • A method for professional organizations to engage and serve their membership communities

  9. Pathway and Lead Ed Level Discipline

  10. DLESE Overview Acts as a pathway in the NSDL networkFunding Agency:National Science Foundation • Directorate for Geosciences Scope:Education at all levels (K12, Higher Ed, Lifelong Learning, Research) • Earth system science, all disciplines Structure:Distributed holdings and services, provided and maintained by many organizations • All joined by the DLESE Program Center at the University Corporation for Atmospheric Research

  11. DLESE Collections • Collections of metadata from ~15 institutions • UCAR, NASA, NOAA, GLOBE, National Academy Press, COSEE, Alexandria Digital Library, others

  12. DL Cyberinfrastructure • Distributed Library Archives • Articles, dissertations, education resources • Distributed Services • Web services and APIs • Content and metadata interoperability protocols • Built on archives, or as compounding of services • Distributed Providers • Digital libraries, data holders, publishers, professional organizations, institutional archives & libraries • Challenge: integrating distributed technical and social systems to support learning and knowledge construction

  13. DL Cyberinfrastructure: OAI • OAI protocol is used to aggregate metadata and content to form a union catalog MetadataRepository Metadata and content repositories (aggregations)Examples: NSDL, DLESE OAI harvesting Librarycatalogs Library catalog Librarycatalog Metadata and contentproviders

  14. OAI and Data Providers • OAI protocol in use by some data providers to share metadata MetadataRepository Metadata repositoriesabout data OAI harvesting WMO Threddscatalogs Metadata about data

  16. Approach: Layered Knowledge Services(Sumner et.al., 2004) • Level 1: Characterization services • Item level/collection level metadata, data registration • Level 2: Filtering services • Search and browse, data slice, partitioning • Level 3: Elaboration services • Annotations, reviewing, linking through concepts, augmenting with vocabularies • Help users, and programs, to make connections • Level 4: Viewing and Interacting Services • Visualization Tools, Cognitive Tools, Content Management Systems, etc.

  17. Examples with DLESE and NSDL • Characterization Services • Cataloging tools • Metadata and content standards for collecting and describing educational materials • Filtering Services • Search Services and APIs: REST and JavaScript services for discovering, displaying and using content • Elaboration Services • Concept Space Interchange Protocol: a concept space web service • Viewing and Interacting Services • Library search and portal pages: www.dlese.org, www.nsdl.org • Strand Map Service: Visualization of concept maps • NSDL Expert Voices: Interactive knowledge sharing blog space • DLESE Teaching Boxes: Classroom-ready instructional units created by teachers, scientists and designers

  18. Perform textual search Return resources by subject Display the results Page through the results View expanded metadata FCOSEE Web Portal Search service is used to… Limit the domain to the ocean sciences and boost Florida-related resources automatically

  19. Select resources by category GLOBE Teachers Guide Search service is used to…

  20. Perform textual searches Display selected resources GLOBE Teachers Guide Search service is used to…

  21. Concept Space Interchange Protocol: Used to create visual concept map interfaces Search service: Used to display resources aligned to concepts Strand Map Service Exploring by interactively browsing concepts

  22. Geoscience Research and EducationNetwork • A common cyberinfrastructure of archives, services and providers for research and education activities • Layered knowledge services: A structure on which to utilize the network • Characterization, Filtering, Elaboration, Viewing & Interacting, Contributing, Reuse
