1. FRBR information exchange Thomas Hickey & Jenny Toves OCLC Research

2. Current FRBR information exchange  Sets of MARC-21 records Both bibliographic and authority Sometimes extended  pKeys  Unique pKeys  Lists of sets of control numbers  xISBN web service  superWork records

3. Some background  Our FRBRization has been done primarily at the work level We have FRBRized OCLC WorldCat ~60,000,000 records ~1,000,000,000 holdings Used in Open WorldCat, FictionFinder now Will be visible in FirstSearch displays this fall Norwegian BIBSYS records Finish national bibliography (now in WorldCat) Electronic thesis metadata  Processing done on a 24-node Beowulf Linux cluster

4. MARC 21 bibliographic data  Basic method of accepting information  Other formats get mapped into it  Fields we use: Author main entry Titles ISBN Personal name added entries Language  Extensions BIBSYS use of 490 fields to indicate hierarchy

5. MARC 21 Authority data  Map personal names using cross references  Map author-titles using cross references  Fields we currently use 008 fixed field 100, 130, 400  Extensions Files of additional cross references Common title patterns xISBN matching

6. pKeys  An author-title key for matching  Derived from MARC-like records & authority data ocm00019613 shakespeare, william\1564 1616/hamlet ocm00615676 /hamlet/shakespeare, william\1564 1616 ocm14055779 hamlet motion picture 1948 ocm00290352 /hamlet/ocm00290352

7. Unique pKeys  pKeys that have been sorted and counted 692 sw00008899 milton, john\1608 1674/poems 691 sw00255854 puccini, giacomo\1858 1924/tosca 690 sw00020874 chaucer, geoffrey\d 1400/canterbury tales 688 sw00237074 melville, herman\1819 1891/moby dick 682 sw03620985 china/laws etc

9. xISBN web service  Takes an ISBN as input  Returns list of ISBNs in associated work  Significant processing Starts with control-number list of work-sets Uses ISBNs to pull work-sets together Allows fuzzy-matching on author/title Ends up with consistent clusters In general larger than those in control-number list

10. xISBN examples [0130188549, 0130188476]:0130188549 sw11067396 barnea, amir/agency problems and financial contracting sw13096363 barnea, amir/agency problems on financial contracting [000713407x, 0007126360, 0007134053, 0007134061, 0007126441]:000713407x sw48486275 /collins new school dictionary/ocm48486275 sw49740193 /collins new school dictionary/ocm49740193 sw49740203 /collins new school dictionary/ocm49740203

12. superWorks format  Developed for FictionFinderFictionFinder  XML format  Includes expression-level information All the information needed  We are adapting it to the Curioser projectCurioser

13. superWork record layout  pKey  # manifestations, holdings, sw-id, control #s  publication dates  expressions expression classes language authors titles subjects components author, title, publication data

14. Summary  Simpler when only work-level relationships are needed  Even for work-level relationships, a number of different formats are useful  Information needed for an interface gets much more complicated
