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

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 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

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

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

DLESE Overview Acts as a pathway in the NSDL network Funding 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

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 Metadata Repository DL Cyberinfrastructure: OAI  OAI protocol is used to aggregate metadata and content to form a union catalog Metadata and content providers Library catalogs Library catalog Library catalog OAI harvesting

Metadata repositories about data Metadata Repository OAI and Data Providers  OAI protocol in use by some data providers to share metadata Metadata about data WMO Thredds catalogs OAI harvesting

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:  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 Examples with DLESE and NSDL
