DLESE and NSDL: Digital Library Components of
Cyberinfrastructure
International Workshop of Cyberinfrastructure for Geosciences
IWCG2006 - Beijing, China July 21-23, 2006

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
Overview
NSDL and DLESE Digital Library (DL) components of
cyberinfrastructure Knowledge representation in DLs Example applications
Digital Libraries: Overview
Discovery of educational resources, data sources, tools, visualizations, etc.
Resource and information sharing and reuse
Support learning and knowledge formation
NSDL 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
DLESE 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
NSDL OverviewFunding 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, comprisingUniversity Corporation for Atmospheric Research – Kaye HoweCornell University – Dean KrafftColumbia University – Kate Wittenberg

DLESE Collections
Collections of metadata from ~15 institutions
UCAR, NASA, NOAA, GLOBE, National Academy Press, COSEE, Alexandria Digital Library, others
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
Metadata and content repositories (aggregations)
Examples: NSDL, DLESE

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.
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
