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

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
NSDL
DLESE

• 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

• 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 RD project, now part
  of NSFs 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

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 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

13
DLESE Collections

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

14
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

DL Cyberinfrastructure OAI

• OAI protocol is used to aggregate metadata and
  content to form a union catalog

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.
