  7. Wider coverage Published, unpublished, objects, licensed, archival • Multiple sources Machine generated Info. professionals, scholars, researchers, enthusiasts • Broader use of APIs Multiple views Better context Better navigation More mashups Authorities touch everything

  8. Controlling WorldCat • Virtual International Authority File • WorldCat Identities

  9. Controlling names in WorldCat • Has been done semi-manually • Encourages review of all links • For Identities we did this automatically • Research copy of WorldCat • Very aggressive matching • How to move links to WorldCat?

  10. Pretend you are a Connexion Client • Program to: • Log in • Search for record • Verify heading hasn’t changed • Insert authorized form • Add link • Do replace

  11. Then just replace 26 million records • Each update takes two transactions • Retrieve the record • Replace the record • If it takes 2 seconds/update • 52,000,000 seconds • ~ 2 years

  12. But, we can run multiple clients • Connexion can handle 40+ of these clients • ~ 20 records/second • Offline processing has limited capacity • Run 32 clients for 12 hours for 16 updates/second • ~700,000 overnight • Up to a million/day • 3 million/week • 2-3 months elapsed time

  13. VirtualInternationalAuthorityFile

  14. DNB Bib & Authority BnF Bib & Authority LC Bib & Authority VIAF • ~7.5 million personal name authority records • ~25 million bibliographic records • ~1.2 million links between files VIAF

  15. Match on • Names and dates in headings • Standard numbers • Titles • Coauthors • Publishers • Personal name as subject

  22. Next steps for VIAF • Merged display • Better documentation • More participants • Geographics

  23. Australian Identities (in WorldCat)

  24. Editing

  25. Merged result • Immediately visible in Identities • Persistent in Identities • Information fed into established channels

  26. Implementation • SRU/SRW server (Z39.50 for the Web) • XML returned • XSLT style sheets transform it to HTML

  27. Syndication • Searchable via SRU, OpenURL • Sitemaps for harvesters • HTML for harvesters and mobile devices • Links in Wikipedia
