  3. Outline • Case Study: NDLTD • Case Study: CSTC • Case Study: CITIDEL • Interoperability: OAI, ODL • Conclusions

  4. 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 (NDLTD) http://www.ndltd.org A Digital Library Case Study

  5. The Networked Digital Library of Theses and Dissertations www.NDLTD.org Training Authors Expanding Access Preserving Knowledge Improving Graduate Education Enhancing Scholarly Communication Empowering Students & Universities Leader of the Worldwide ETD (Electronic Thesis and Dissertation) Initiative

  6. NDLTD IT Ed. (Tech) Grad Program Library

  7. Key Ideas: Networked infrastructure Scalability University collaboration Workflow, automation Education is the rationale 8th graders vs. grads Maximal Access Authors must submit Standards PDF, SGML, MM, MARC, DC, URNs, Federated search

  8. What led to today’s meeting? • 1987 mtg in Ann Arbor: UMI, VT, … • 1992 mtg in Washington: CNI, CGS, UMI, VT and 10 universities with 3 reps each • 1993 mtg in Atlanta to start Monticello Electronic Library (regional, US Southeast): SURA, SOLINET • 1994 mtg at VT: std: PDF + SGML + multimedia objects • 1996 funding by SURA, US Dept. of Education (FIPSE) • 1997 meetings in UK, Germany, ... • 1998 – 1st symposium – Memphis (20) • 1999 – 2nd symposium – Blacksburg (70) • 2000 – 3rd symposium – St. Petersburg (225) • 2001 – 4th symposium – Caltech (200) • 2002 – 5th symposium–BYU; 2003–Berlin; 2004–Kentucky

  9. What are the long term goals? • 400K US students / year getting grad degrees are exposed / involved • 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

  21. ETD-MS • ETD Metadata Standard • XML-encoded metadata standard (content and encoding) for Electronic Theses and Dissertations (ETDs) • in part conforming to Dublin Core (DC) • using UNICODE • (optionally / later using RDF) • Well specified relationship with MARC

  22. NDLTD Members and ETD-MS • NDLTD members will • Share metadata for their ETDs • Providing that in either ETD-MS • Or if they use a version of MARC locally, work to have that eventually shared in either MARC21 or UNIMARC • Run OAI, either locally or in consortia, so their metadata can be harvested, according to necessary terms and conditions

  23. Some recent additions • ETD individuals support • http://etdindividuals.dlib.vt.edu:9090 • ETD discussion (e-prints) • http://ndltdpapers.dlib.vt.edu:9090 • Conference papers and presentations • http://www.ndltd.org/WVUproc.htm • Marcel Dekker book in publication

  24. What are plans at VT? • LOCKSS welcomed us • Lots of Copies Keeps Stuff Safe • MARIAN: harvest, crawl/scrape, fed search • Metadata crosswalks and format converters • XML schema for ETDs • Open Digital Libraries: easy to add services! • http://oai.dlib.vt.edu/odl

  25. Union catalog (OCLC) • OCLC will expand the OAI data provider on TDs • Will get data from WorldCat • Will harvest from all who contact them • Need DC and either ETD-MS or MARC • Will have a set for ETDs

  26. Union catalog (VTLS, VT) • VTLS will enhance search/browse service for ETDs • Will harvest from OCLC’s set of ETD records • Will receive through other mechanisms, too • Will work with MARC-21 and ETD-MS • VT will continue to offer experimental services

  27. NUDL(www.nudl.org)Int’l Research Support • Networked University Digital Library • Partners: Germany, Mexico (Puebla and Monterrey), Brazil • Problems: Multilingual search, high performance DLs, requirements/usability, … • Start with ETDs, then expand to other student works, portfolios, data sets, (CS) courseware, ...

  28. Outline • Case Study: NDLTD • Case Study: CSTC • Case Study: CITIDEL • Interoperability: OAI, ODL • Conclusions

  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 to build a powerful base of support for learners, upon which a variety of courses, self-study tutorials & reference resources can be built.
