2. What is CITIDEL? • Computing and Information TechnologyInteractive Digital Educational Library • Consortium • Virginia Tech (lead institution) • Hofstra University • Penn State University • The College of New Jersey • Villanova University • Collection Component of NSDL

3. Digital Libraries • Some familiarity • ACM Digital Library • IEEE/CS Digital Library • Others • Content • Refereed and reviewed online materials • Interactive • Search facilities • Download materials (fee structure)

4. Dynamics • Context: • Global movement toward Digital Libraries • See April 1998 (& May 2001) Communications of the ACM • NSF 00-44 effort: • Science, Mathematics, Engineering, and Technology Education (SMETE) Digital Library • Now called Science, Technology, Engineering, and Mathematics (STEM) • Focused on undergraduates • Three workshops, yearly increasing funds • Instituted new calls

5. What’s a NSDL? National Science Foundation STEM (Science, Technology, Engineering, Mathematics) Educational Digital Library <http://www.nsdl.nsf.gov/> Over $100 million initiative  

6. Transitions • NSDL will operate as a distributed federation • Contains separate parts for each key discipline • Expected to be a global effort in the future • From NSF DLI-1 to NSF DLI-2 • NSF DUE innovation, dissemination • SMETE Library  NSDL • NSDL  LEARNS

7. Learning Environment and Resources Network for STEM Education (LEARNS) LEARNS Users Tools Content “The network is the library.”

8. LEARNS Connects • Users • Students, educators, life-long learners • Content • Structured learning materials; large real-time or archived datasets; audio, images, animations; primary sources; digital learning objects (e.g., applets); interactive (virtual, remote) laboratories; ... • Tools • Search; refer; validate; integrate; create; customize; publish; share; notify; collaborate; ...

9. Users Tools Content LEARNS Supports Learning communities (Profiles) Application services (Protocols) Customizable collections (Metadata)

10. Environments for Communication Collaboration Creation Validation Evaluation Recognition ... Discovery Stability Reliability Reusability Interoperability Customizability ... of Resources LEARNS Enables and

11. Overall Goal Tracks Core Integration - FY00 pilots - FY01 full Collections Services Targeted Research LEARNS (Beta test in 2002)

12. NSDL Program Tracks • Core Integration Coordinate a distributed alliance of resource collection and service providers; and ensure reliable and extensible access to and usability of the resulting network of learning environments and resources • Collections Aggregate and actively manage a subset of the digital library’s content within a coherent theme / specialty • Services Increase the impact, reach, efficiency, and value of the digital library in its fully operational form • Targeted (Applied) Research Have immediate impact on one or more of the other three tracks

13. Core Integration Key Concepts • NSDL • An “Education Layer” over web • Will be seen by • Users, as one library with many portals • Builders, as offering a spectrum of interoperability • Major objectives of Core Integration (CI) are to help NSDL successfully achieve • Diverse collections • User interfaces & library services • Educational excellence • Access and content management • Framework for evolution

15. Collections • Discovery of content • Classification and cataloguing • Acquisition and/or linking; referencing • Disciplinary-based themes • Define a natural body of content • Other possibilities are also encouraged • Access to massive real-time or archived datasets • Software tool suites for analysis, modeling, simulation, or visualization • Reviewed commentary on learning materials and pedagogy

16. Services • Help services such as frequently asked questions • Synchronous/asynchronous collaborative learning environments using shared resources • Mechanisms for building personal annotated digital information spaces • Reliability testing for various digital learning objects • Audio, image, and video search capability • Metadata system translation • Community feedback mechanisms
