No notes for slide
  • For the National Archival Authorities Cooperative meeting (Washington, D.C.) -- with appreciation to my colleague Thom Hickey who has provided slides for my reuse and adaptation
  • Image of William Shakespeare: http://en.wikipedia.org/wiki/File:Shakespeare.jpg (public domain) In the National Portrait Gallery, London
  • To make our catalogs work
  • Within the community, ‘linked data’ of limited help. We already have mechanisms, although they could be used to a greater extent.
  • Needs to be shareable between communities.
  • Statistics as of August, 2012
  • Explicit links should make it easier to relate library metadata with others as well as improve interoperability within the library communityWe especially need links between article authors and library-controlled authors!Toward that we hope to work with a group at CERN with the inSpire physics literature collection.
  • Want to provide an identifier for all sorts of creators to form a link across databases on the web
  • WP: Notable Syriac prose writer and a vehement champion of Miaphysitism
  • Stand-alone authority file that becomes a ‘source’ to VIAF.
  • Current initiatives: Scopus, Scholar Universe, Researcher ID, REPEC, etc.ORCID may offer the best chance for institutional repositories to quickly get an ID for use in their systems
  • ~38 million just for personal names + 10M corporate and ~50K subject-names
  • Transcript

    • 1. VIAF for NAAC 2012 October Eric Childress OCLC Research
    • 2. Prologue
    • 3. “Whats in a name? that which we call a roseBy any other name would smell as sweet.”
    • 4. Why do we like authorities?1. To enable a person to find a book of which either (A) the author (B) the title is known. (C) the subject2. To show what the library has (D) by a given author (E) on a given subject (F) in a given kind of literature3. To assist in the choice of a book (G) as to its edition (bibliographically) (H) as to its character (literary or topical) Charles A. Cutter: Rules for a printed dictionary catalog, 1876
    • 5. What do authority files control?• Names! – Persons – Corporations – Places – Uniform Titles – Families – Trademarks – Concepts
    • 6. But we also control• Collective authors• Pseudonyms• Imaginary characters• Deities, saints, angels• Whales, horses, dinosaurs• Buildings• Ships, telescopes, space ships, missiles• Kings, Popes, Presidents• Cities, lakes, mountains
    • 7. Library data is• Trusted• Understood• Reasonably interoperable• Complex
    • 8. Shareable metadata• Public• Simple• Supply data rather than APIs – Avoid idiosyncratic protocols • Z39.50 • MARC-21 • ISO2709 8
    • 9. VIAF (VIRTUAL INTERNATIONALAUTHORITY FILE)
    • 10. Brief history of VIAF• Intellectual origins of idea go back several decades (linked to IFLA UBC concept)• In 1990’s research project by LoC & DDB to identify names common to NAF and PND• 1998 – LoC, DDB, OCLC began proof of concept work• 2003 – VIAF Consortium formed (LoC, DNB, OCLC) & 2007 (BnF) – Participant/Contributor tiers• 2012 – VIAF transitioned to OCLC service – Each agency has bi-lateral standard agreement with OCLC – VIAF Council advises OCLC
    • 11. What is VIAF?• Merge of 24+ national level authority files• Cooperative run by OCLC with VIAF Council• 29 million authority records• 112 million bibliographic records• 22 million merged clusters• Migrating to an OCLC service
    • 12. Enhancing authoritiesBibliographic Derived Record Authority Processed Authority Authority Record

    • 18. Shakespeare – Alternate Name Forms
    • 19. Shakespeare - various
    • 20. Shakespeare -- various

    • 22. A world of linked datahttp://richard.cyganiak.de/2007/10/lod/imagemap.html
    • 23. Applications• FRBR matching – Better matching of non-English metadata – Uniform identifier across all languages• Authority control for cataloging• Better regionalization of catalogs• Minimize differences across languages of cataloging
    • 24. Recent directions• Transfer VIAF from OCLC Research to a supported OCLC service• Available under ODC-By – http://viaf.org/viaf/data• Better integration of VIAF and WorldCat• Linking between identifiers• Increased use of explicit links in cataloging and other metadata
    • 25. Activities OCLC Research involved in• ISNI• Scholar’s Funnel• xA• ORCID• WorldCat Identities
    • 26. ISNI (International Standard NameIdentifier)
    • 27. ISNI International Standard Name Identifier• Draft ISO standard: … aspires to provide a means to uniquely identify creators, including authors, composers, artists, cartographers and performers, among others. Such an authoritative identifier will serve to provide a link for occurrences of the identity across databases on the web• Driven by rights-holders – Publishers – Rights agencies representing authors, artists
    • 28. Scholar’s Funnel
    • 29. Scholar’s funnel?• Currently Syriac names (Syriac Reference Portal) – Interest from Arabic scholars• Uses xA as the infrastructure• Next project: Islamic Manuscripts Catalogue Online
    • 30. xA (eXtended Authorities)
    • 31. xA• A way to ‘control’ VIAF• A way to enhance VIAF
    • 32. xA as a control• Create a xA record and link it to other ‘source’ records• Create two xA records and link them to different ‘source’ records
    • 33. ORCID (Open Researcher &Contributor ID)
    • 34. • Open version of Thomson-Reuter’s Researcher ID• Most ‘social’ – Claiming IDs – Interactive verification of associated works – Pulling together several current initiatives• Driven by STM, university communities• Primarily interested in researchers• Large number of participants• Mostly concerned with present and future names
    • 35. WorldCat Identities
    • 36. WorldCat IdentitiesA page for every name in WorldCat
