  19. UNESCO and ETDs(by Axel Plathe at ETD2003) • Promoting the use of the Internet as a tool for disseminating scientific knowledge • Facilitating the transfer of ETD expertise from developed to developing countries • 1998: Member of the NDLTD Steering Committee • 1999: First UNESCO ETD meeting on ETD internationalisation • 2002: “UNESCO Guide to Electronic Theses and Dissertations” • 2003: Model training programmes and training courses • 2003: Sponsor pilot projects • 2003: Pilot projects (Africa, Europe, Latin-America)

  20. Union catalog: OCLC • OCLC will expand OAI data provider on TDs. • Is getting data from WorldCat (so, from many sites!). • Will harvest from all others who contact them. • Need DC and either ETD-MS or MARC. • Has a set for ETDs.

  21. OCLC SRU Interface

  22. ETD Union Search Mirror Site in China (CALIS)(http://ndltd.calis.edu.cn – popular site!)

  23. VTLS Service’s Support ofContent Languages • The VTLS service for NDLTD supports different languages. These are: • English • German • Greek • Korean • Portuguese • Others – which are most needed ???

  24. ETDs: Library Goals • Improve library services • Better turn-around time • Always available • Reduce work • catalog from e-text • eliminate handling: mailing to ProQuest, bindery prep, check-out, check-in, reshelving, etc. • Save space

  25. Why ETD? Short Answer • For Students: • Gain knowledge and skills for the Information Age • Richer communication (digital information, multimedia, …) • For Universities: • Easy way to enter the digital library field and benefit thereby • For the World: • Global digital library – large, useful, many services • General: • Save time and money • Increased visibility for all associated with research results

  26. What are we doing? • Aiding universities to enhance graduate education, publishing and IPR efforts • Helping improve the availability and content of theses and dissertations • Educating ALL future scholars so they can publish electronically and effectively use digital libraries (i.e., are Information Literate and can be more expressive)

  27. Outline • Acknowledgements • Digital Libraries • NDLTD • Recent and Future Work • Conclusions

  28. Recent and Future Work • OAI • Quality Analysis • Preservation (LOCKSS) • Automatic Classification to Identify Sub-collections and Categories • Logging Standards • Other Services and Enhancements

  29. OAI - Open Archives Initiative • Advocacy for interoperability • Standard for transferring metadata among digital libraries • Protocol for Metadata Harvesting (PMH) • Simplicity • Generality • Extensibility • Support for PMH => Open Archive (OA)

  30. OA 1 OA 2 OA 4 OA 3 OA 5 OA 6 OA 7 OAI – Black Box Perspective

  31. Metadata harvesting The World According to OAI Service Providers Discovery Current Awareness Preservation Data Providers

  32. Metadata Specifications and Metadata Format: Conformance • Based on ETD-MS

  33. LOCKSS • Lots of copies keep stuff safe • Stanford (Vicky Reich) • Initial focus on lower levels • Initial content: journals • Emory (Martin Halbert) • Help deploy and adapt • Help apply in other contexts • Another registry • Set of publisher manifests (information providers) • Set of storage systems (archival storage) • NDIIP: AmericanSouth, MetaArchive

  34. NDLTD Sub-collections,PACS Automatic Classification

  35. XML-based DL Log Standard • Log analysis • is a source of information on: • How patrons really use DL services • How systems behave while supporting user information seeking activities • Used to: • Evaluate and enhance services • Guide allocation of resources • Common practice in the web setting • Supported by web servers, proxy caches • DL Logging can be more detailed

  36. The XML Log Format Log Transaction Timestamp Statement SessionId MachineInfo Event Timestamp Statement SessionInfo RegisterInfo Action StatusInfo Update StoreSysInfo Search Browse Collection Catalog SearchBy Timeout PresentationInfo QueryString

  37. Future Work – 1 of 3 • Collection • Cover all universities in Australia, the region, and the world • Expand from dissertations to theses to undergrad theses to reports to e-portfolios • Add in page images of back files or at least bib records (retrospective)

  38. Future Work – 2 of 3 • Promote use of ETDs • Collaborate with Scirus, Google Scholar, … • Support students so have DOIs, resolved references, XML works • Support cross language, multilingual, multimedia search/browse • Provide aids to classification into DDC or domain-specific classification
