1 VIAF for NAAC 2012 October Eric Childress OCLC Research

2 Prologue

3 “What's in a name? that which we call a rose By 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 (C) the subject 2. To show what the library has (D) by a given author (E) on a given subject (F) in a given kind of literature 3. To assist in the choice of a book (G) as to its edition (bibliographically) (H) as to its character (literary or topical) is known. 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 INTERNATIONAL AUTHORITY 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 servicetransitioned – 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

15 Record Flow SWNL Bib & Authority BnF Bib & AuthorityLC Bib & Authority VIAF 29 million authority records 31 million links between authorities

16 William Shakespeare

17 Shakespeare- Uniform Titles

18 Shakespeare – Alternate Name Forms

19 Shakespeare - various

20 Shakespeare -- various

21 Shakespeare - RDF

22 A world of linked data

23

24 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

25 Recent directions Transfer VIAF from OCLC Research to a supported OCLC service Available under ODC-By – Better integration of VIAF and WorldCat Linking between identifiers Increased use of explicit links in cataloging and other metadata

26

27 Activities OCLC Research involved in ISNI Scholar’s Funnel xA ORCID WorldCat Identities

28 ISNI (International Standard Name Identifier)

29 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

30 Scholar’s Funnel

31 Scholar’s funnel? Currently Syriac names (Syriac Reference Portal) – Interest from Arabic scholars Uses xA as the infrastructure Next project: Islamic Manuscripts Catalogue Online

32

33 xA (eXtended Authorities)

34 xA A way to ‘control’ VIAF A way to enhance VIAF

35 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

36

37 ORCID (Open Researcher & Contributor ID)

38 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

39 WorldCat Identities

40 WorldCat Identities A page for every name in WorldCat
