  1. Herbert Van de Sompel Cornell University Computer Science – Digital Library Research Group OAI metadata harvesting specifications Workshop on OAI and peer review journals in Europe Geneva, Switserland – March 22nd to 24th 2001 herbert van de sompel

  2. 0 a brief history of the OAI herbert van de sompel

  3. the OAI roots The Open Archives Initiative has been set up to create a forum to discuss and solve matters of interoperability between preprint solutions, as a way to promote their global acceptance. Paul Ginsparg, Rick Luce & Herbert Van de Sompel => Santa Fe Convention: preprint metadata harvesting herbert van de sompel

  4. interest from other communities • Digital Library Federation meetings • ~ research library community has many materials • for which they would like to ‘expose’ metadata • OAI San Antonio meeting: • ~ interest from librarians, publishers, others, ... herbert van de sompel

  5. resulting actions: organizational • establish organizational stability for the OAI: • institutional backing from CNI & DLF • steering committee: policy guidance • technical committee: technical specifications • executive group: day to day coordination • workshops: public dissemination, feedback herbert van de sompel

  6. resulting actions: technical • [09/2000] revise specifications to allow adoption beyond preprints: technical committee • [09/2000-01/2001] compile new specifications: editing by Carl and Herbert • [11/2000-01/2001] alpha-test specifications: oai-alpha group • [01/2001] discontinue the Santa Fe Convention • [01/2001] release version 1.0 of the OAI protocol herbert van de sompel

  7. 1 the OAI Metadata Harvesting protocol herbert van de sompel

  8. The OAMH protocol is a low-barrier interoperability specification for the recurrent exchange of metadata between systems herbert van de sompel

  9. Requests repos i tory harves ter Replies the OAMH protocol service provider data provider 6 herbert van de sompel

  10. A&I image FTXT OPAC e-print federated services herbert van de sompel

  11. A&I image OPAC e-print harvester FTXT metadata harvesting via OAMH metadata FTXT herbert van de sompel

  12. A&I image FTXT e-print OPAC Author Title Abstract Identifer federated services via OAMH metadata herbert van de sompel

  13. Reply • XML Schema • Self contained core concepts in OAMH • low-barrier interoperability • data-provider & service-provider model • metadata harvesting model OAMH protocol HTTP based • shared metadata format and parallel, community-specific metadata formats Dublin Core herbert van de sompel

  14. repos i tory harves ter OAI harvesting tools service provider data provider Datestamp Identifier Set Records herbert van de sompel

  15. repos i tory harves ter OAI harvesting tools service provider data provider • Supporting protocol requests: • Identify • ListMetadataFormats • ListSets • Harvesting protocol requests: • ListRecords • ListIdentifiers • GetRecord herbert van de sompel

  16. repos i tory harves ter supporting protocol requests service provider data provider ListMetadataFormats • ListMetadataFormats / Time / Request • REPEAT • Format prefix • Format XML schema • /REPEAT herbert van de sompel

  17. repos i tory harves ter harvesting requests service provider data provider * from=a * until=b * set=klm ListRecords * metadataPrefix=dc • ListRecords / Time / Request • REPEAT • Identifier • Datestamp • Metadata • /REPEAT herbert van de sompel

  18. Applications of the OAMH protocol? • federated services [S&R, SDI, alerting, linking, ...] • database synchronization • harvesting the deep Web • ... herbert van de sompel

  19. 2 OAI - status herbert van de sompel

  20. revision of specifications • freeze specifications for 12 -18 months: • stable for experimentation; not definitive • minimize risk for early adopters • maximize chances for future interoperability across communities herbert van de sompel

  21. software to run OAI repository • eprints.org - U. Southampton • open source metadata server - OCLC • NT OAI server - U. Illinois • Aleph 500 - Ex Libris • Z39.50  OAI gateway - Virginia Tech (ongoing) • MARC to DC convertor - OCLC • we expect a lot more ... • listed on OAI site herbert van de sompel

  22. tools to support OAI implementation • Hussein’s Repository explorer • W3C XSV Schema Validator • XML Spy • the OAI comformance tester: • part of OAI registration service for repositories • listed on OAI site herbert van de sompel

  23. modes of running OAI 1.0 repository • mode 0: • no registration of repository in the OAI registry herbert van de sompel

  24. modes of running OAI 1.0 repository • mode 1: • registration of repository in public OAI registry • [includes validation of replies] existence of the repository is visible herbert van de sompel

  25. modes of running OAI 1.0 repository • mode 2: • registration of repository in public OAI registry • usage of the OAI format for identifiers existence of the repository is visible resolver for OAI formated identifiers herbert van de sompel

  26. implementation status • early adoption by preprint community • but also by others herbert van de sompel

  27. implementation status • data providers: • 20 registered repositories (US and Europe) arXiv OCLC Thesis and Dissertations Perseus Digital Library PhysNet Oxford Text Archive Library of Congress -- American Memory CogPrints Humboldt University MIT Thesis Linguistic Data Consortium Resource Discovery Network herbert van de sompel

  28. implementation status • service providers: • ARC • Open Language Archives • soon to be listed on OAI site herbert van de sompel

  29. implementation status • Mellon Foundation funding for OAI-based projects: data providers and service providers • NSF Digital Library interest in OAI-related projects • Close contacts with SPARC, DLF, CNI herbert van de sompel

  30. communication re OAI • lists: subscribe via http://www.openarchives.org • oai-general list • oai-implementers list • web: http://www.openarchives.org • FAQ: http://www.openarchives.org/faq.htm • mail: openarchives@openarchives.org herbert van de sompel
