The DLESE Vision

• Supports all aspects of ESS in formal and
  informal educational settings
• Collections of high quality teaching and learning
  resources
• Interfaces and tools to allow exploration of
  Earth data sets
• Services to help users effectively create and use
  materials

Digital Library - Basics

• Whats a Digital Library
• Digital Library, Digital Archive, Data Library,
  Metadata Repository or Registry, Subject
  Gateway...
• Collections
• Scope, policies (accession), cataloging
  classification, management, workflows
• Services
• Search and browse, reference, ask-a, bulletin
  boards, news

7
Extending Digital Library

• Quality of Collection
• Review systems (e.g. JESSE, CRS)
• Reviewed Collections (e.g. DWEL)
• Enhanced Services
• Standards, concepts, knowledge
• Strand Map Service (CU/AAAS), Gazetteers (ADL)
• Distributed services and the CI, Grid
• Library as Publisher and Distributor
• Self-publising to the web encouraged
• Impact on resource creators
• Editorial process, workflow, versioning

8
Distributed Library

• Distributed Systems
• Collections
• Services
• Heterogeneity (H/W, S/W, Architectures)
• Interoperability Dimensions
• Social
• Policy
• Semantic
• Technology
• Integrated User Experience

Library Building Strategy

• Community governance and ownership
• Distributed and representative management
• Distributed building process by community
• DLESE Program Center
• Infrastructure development (OAI, ADN, Discovery,
  DCS)
• Program continuity
• Integration services, support
• Service Centers (starting summer 2003)
• Collections, data, community, evaluation
• Users as contributors
• Community-developed collections, services, and
  technology
• User-centered design philosophy

A Geoscience Node in NSDL

• Partnership with NSDL
• Standards, policies, technologies
• Support from NSDL, DLI, ITR for collections and
  services that will benefit DLESE
• Geo-referencing and gazetteers (UCSB)
• Peer reviewing services (Columbia, USRA)
• Thematic Data Sets (Unidata)
• GEON (SDSC)
• Encyclopedia of Earthquakes (SCEC)
• Digital Water Education Library for K-12 (DWEL)
• AVC (Argonne)
• SIOExplorer (Scripps)
• Persistence (SDSC)

13
Educators and learners currently

• Work at a distance
• Publish on web
• Access scientific databases
• Collect and analyze data
• Visualize results of complex datasets
• Consider themselves part of a community
• Work in an interdisciplinary fashion

14
Current Problems Shared Equally by Educators
Researchers

• Relevant data (for a given context) often are
• Hard to find (re a named place or event, e.g.)
• Hard to acquire or access
• Once found acquired, such data often are
• Hard to understand
• Hard to use, especially in a specific tool or in
  combination with other types of data
• Difficulties are compounded in multidisciplinary
  education research (e.g. Earth-system studies)
• Potential of Cyberinfrastructure, Grid
  technologies
• Domain applications thrusts for education

15
Reflecting on Cyberinfrastructure

• DLs a visible artifact of cyberinfrastructure
• Referenced in reports, requested at workshops
• Research to Operations
• Performance, scaling, reliability, replication
• Access
• Gap (around 26000 schools)
• Direct or indirect use of services
• Interoperability (metadata, protocols, etc.)
• Archiving and persistence
• Inclusion of allied communities
• Traditional text and journal publishers,
  Librarians
• Informal science educators
• E-commerce e-govt groups
• Community building/communities of practice
• Intellectual Property

16
Evaluation

• At every stage
• Include users in library building
• Community input, focus groups, workshops
• Short build-test-evaluate cycles
• Is this really what you wanted?
• Education impact
• Improve teaching and learning about the Earth
  system
• How to quantify and measure
• Basis of DLESE future
