  6. Locating Digital Libraries in Computing and Communications Technology Space Digital Libraries technology trajectory: intellectual access to globally distributed information Communications (bandwidth, connectivity) Computing (flops) Digital content less more (Slide from S. Griffin, NSF)

  7. Service Machine 1 Service Machine 3 PetaPlex Complex Service Machine 2 Service Machine 4 FRONT END MACHINE RS/6000, 1G RAM, 4 Proc. Nanoserver PetaPlex Core Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver Nanoserver

  8. PetaPlex • Digital Library Machine (“super” object store): Parallel computer / storage utility • Research: inverted files, video server, … (supported by IBM, AOL, NSF, …) • Knowledge Systems Incorporated is supplying VT-PetaPlex-1 with 2.5 terabytes through 100 nodes: • Net connection + 25GB disk + 233 MHz Pentium + Linux

  9. MARIAN • Multiple Access Retrieval of Information with Annotations • (Marian the Librarian …) • Evolved from CODER system to a distributed Online Public Access Catalog (OPAC), then DL backend, now becoming a full DL system • From C/C++ to Java • Future: NDLTD, NUDL, PetaPlex • Use for campus collection management • Use for www.theses.org as centralized system with gateway services: OAI, Harvest, Z39.50, …

  10. User User User User MARIAN Layers User Interface Layer User Information Layer Search Engine Layer Database Layer

  11. MARIAN Parallelism

  12. ENVISION • NSF “A User-Centered Database from the Computer Science Literature” (1991-93) • Collected bib/typesetter data, converted to SGML • Scanned thousands of page images • MARIAN search engine - can be made available (also applied to the Virginia Tech library catalog) used as part of a prototype object-based DL, with tailored visualization interface (L. Nowell dissertation)

  15. Core of DL • Collecting • Authoring, Repositories, Archives, Museums, … • Organizing • Packaging of Data and Metadata, Storing • Naming/Identifying and Cataloging • Classification, Clustering, … • Serving • Indexing, Linking, Summarizing, Visualizing • Browsing, Accessing, Searching, Filtering, Retrieving, Distributing, Using, …

  19. Domain: graduate education, research Genre: ETDs = electronic theses & dissertations Submission: http://etd.vt.edu Collection: http://www.theses.org Project: Networked Digital Library of Theses & Dissertations http://www.ndltd.org (NDLTD– remember: ND LTD / NDL TD) (also, newer NUDL: Networked University Digital Library, with e-courseware, etc.) A Digital Library Case Study

  20. Status of the Local Project • Approved by university governance Spring 1996; required starting 1/1/97 • Submission & access software in place • Submission workshops for students (and faculty) occur often: beginner/adv. • Faculty training as part of Faculty Development Initiative • Over 3000 ETDs in collection • Some have audio, video, large images, software, … • Millions of accesses/yr – 100s to 1000s per work

  21. What are the long term goals? • Attract all TDs/yr: 50K D-US, 25K D-Germany, 10K TD-Canada, … • >200K/yr rich hypermedia ETDs that may turn into electronic portfolios (images, video, audio, …) • Dramatic increase in knowledge sharing: literature reviews, bibliographies, … • Services providing lifelong access for students: browse, search, prior searches, citation links • Hundreds/thousands of downloads / year / work

  27. ETD ETD Workshop/Training Policies Inspection/Approval Build Local ETD Site Digital Library

  28. CS Teaching Center (CSTC) • Collection of reviewed online resources used to aid in teaching of Computer Science • Supports author submission and peer-review process for new ACM Journal of Educational Resources In Computing (JERIC) • Connected with NSDL (NSF 00-44) • http://www.cstc.org

  29. CS Teaching Center (CSTC) • Instead of building large, expensive multimedia packages, that become obsolete and are difficult to re-use, concentrate on small knowledge units. • Learners benefit from having well-crafted modules that have been reviewed and tested. • Use digital libraries as a powerful base of support for learners, upon which a variety of courses, self-study tutorials & reference resources can be built. [See NSF NSDL - National Science (math, engineering, technology education) Digital Library (formerly SMETE-lib) at www.dlib.org/smete/public/smete-public.html; www.smete.org] • iLumina: NSF NSDL grant with COLLEGIS Research Institute/Eduprise, UNCW, TCNJ, …

DL Operational Fall, 2002 NSDL Program NSF: FY 00-02 DLs & UG Earth Systems Education initiated FY 99, continuing DLI 2 - NSF, et al., initiated in FY 98, continuing DLI 2 Special Emphasis in Undergrad Education FY 98-99 Digital Libraries Initiative (DLI 1) - NSF/NASA/ARPA, FY 94-97 (From Lee Zia, NSF)Programmatic History

  33. Expectations of Tracks • Core Integration:to coordinate a distributed alliance of resource collection and service providers, and to ensure reliable and extensible access to and usability of the resulting network of learning environments and resources • Collections:to aggregate and actively manage a subset of the digital library’s content within a coherent theme or specialty • Services:to increase the impact, reach, efficiency, and value of the digital library in its fully operational form • Targeted Research:to have immediate impact on one or more of the other three tracks

  34. Tracks & 29 Projects • 6 Core Integration:Columbia, Cornell, E.Michigan/MERIT, UCAR, UCB, U-Missouri/NCSA (Biology, Eng., Teacher Ed.) • 13 Collections:Atmosphere, Biology, Biosciences, Earth Systems, Engineering, Health Sciences, Math • 9 Services:Competitive Intelligence, Component Environment, Earth Systems J., Metadata NLP, Managing LOs, Peer Review, Video • 1 Targeted Research:Paths
