  12. DL Examples • IBM Digital Library • Virtua ( • Greenstone ( • Eprints ( • Many systems in NSF DLI projects • VT systems: CITIDEL, CSTC, DL-in-a-box, ETANA, MARIAN, NCSTRL, NDLTD

  13. Digital Libraries --- Objectives • World Lit.: 24hr / 7day / from desktop • Integrated “super” information systems: 5S: streams, structures, spaces, scenarios, societies • Ubiquitous, Higher Quality, Lower Cost • Education, Knowledge Sharing, Discovery • Disintermediation -> Collaboration • Universities Reclaim Property • Interactive Courseware, Student Works • Scalable, Sustainable, Usable, Useful

  14. Benefits • Ease of use • Effectiveness • “The benefits of digital libraries will not be appreciated unless they are easy to use effectively.” - IITA Workshop report

  15. DLs: Why of Global Interest? • National projects can preserve antiquities and heritage: cultural, historical, linguistic, scholarly • Knowledge and information are essential to economic and technological growth, education • DL - a domain for international collaboration • wherein all can contribute and benefit • which leverages investment in networking • which provides useful content on Internet & WWW • which will tie nations and peoples together more strongly and through deeper understanding

  16. Reagan Moore Ed Fox June 2002 for NSF

  17. DL Challenges • Preservation - so people with trust DLs • Supporting infrastructure - networks, ... • Scalability, sustainability, interoperability • DL industry - critical mass by covering libraries, archives, museums, corporate info, govt info, personal info - “quality WWW” integrating IR, HT, MM, ... • Need tools & methods to make them easier to build

Extraction What is the status of nk missile launch against japan? It seems that North Korea launch a missile again After North Korea launched a Daipodong missile last month, NK is perceived to proceed to an additional test launch. Korea, US and Japan enter into an alert state, and prepare for a joint response policy. Korea estimates that the additional launch will be on 09/05. Japan estimates that NK’s missile range is short.US information says that there is no sign of launch yet. Translation DARPA Integrated CCLINC Translingual Information System 2-way Speech Transation

  29. Case Study: NCSTRL Costs/Benefits

  30. Definitions • Library ++ (library+archive+museum+…) • Distributed information system + organization + effective interface • User community + collection + services • Digital objects, repositories, IPR management, handles, indexes, federated search, hyperbase, annotation

  31. Definition: Digital Libraries are complex systems that • help satisfy info needs of users (societies) • provide info services (scenarios) • organize info in usable ways (structures) • present info in usable ways (spaces) • communicate info with users (streams)

  32. Case Study: Education • Refactoring Scholarly Communication: • Creating, Sharing, Reviewing, Teaching, Learning, … • Physics: PhysNet • OCKHAM • CSTC, CITIDEL, NSDL • NDLTD

  37. OCKHAM • Simplicity (a la OCCAM’s razor) • Support by Mellon and DLF • Four main ideas: • Components • Lightweight protocols • Open reference models (e.g., 5S, OAIS) • Community perspective and involvement • Now funded by NSF in NSDL, with P2P

  38. OCKHAM Library Network

  39. CS -> CSTC -> CRIM • NSF and ACM Education Committee are funding a 2 year project “A Computer Science Teaching Center” - CSTC - • College of NJ, U. Ill. Springfield, Virginia Tech • Focus initially on labs, visualization, multimedia • Multimedia part is also supported by a 2nd grant to Virginia Tech and The George Washington University: (with curricular guidelines also under development)

  40. 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 to build a powerful base of support for learners, upon which a variety of courses, self-study tutorials & reference resources can be built. • ACM support led to Journal of Educational Resources in Computing (JERIC), accessible from
