  2. LC Update: File access / Pilot expansion Sally McCallum Library of Congress ALA, June 23, 2019

  3. Explosion of activity • LD4 editor brings 17+ institutions into the BIBFRAME environment. • SHARE-VDE from Casalini enables 22+ institutions to see/feel their records as BIBFRAME descriptions. • Innovative Interfaces is into experimentation with discovery with BIBFRAME. • LC is at last able to make its BIBFRAME Work/Instance/Item file publically available and add 50+ more catalogers to the project.

  4. BIBFRAME file access • BIBFRAME Works and Instance file is now publically available through LC’s Linked Data Service (LDS)—better known as ID or id.loc.gov • ID contains many other linked data resources like NAF name authority file, LCSH subject file, and around 100 other resource lists used in MARC and BIBFRAME cataloging and used with the PREMIS preservation standard.

  5. ID.LOC.GOV – Linked Data ServiceSome of the files searchable and available in RDF with URIs: NEW! Etc.

  6. BIBFRAME in ID – starting large and small • Large – BIBFRAME Work and Instance database = entire LC bibliographic catalog + title authorities + holdings • 19 million MARC bibliographic + 1.2 million title authorities • Displays of Works with links to Instances and vice versa • BIBFRAME Works are linked via “BIBFRAME Hubs” • Small – initially simple search • Key word in Work title, Instance title, contributor names, publisher names, publication date • Result sets relevancy ranked

  7. Display snippets

  8. RDF available • Descriptions can also be screened as • RDF/XML • N-triples • JSON • All three offered as • Verbose = data strings + URIs for data • Includes LC’s local/display manipulation properties (bflc) • Compact = URIs for data without strings • Local/display properties eliminated

  9. Try it but it is a work in progress • Displays continuously improved • Searching expanded • Conversion and RDF tweaked • Also remember, LC’s bibliographic data was produced over a span of 100 years so is only relatively consistent. • Changing cataloging conventions • Missing data from retrospective conversion • RDF does not correct data or fill in missing data.

  10. Pilot expansion • Adding 57 more catalogers including: • 10 new catalogers from non-book media areas like sound recordings, notated music, and cartographic • 10 new catalogers from field offices – Cairo, Jakarta, Islamabad, and Nairobi • Training in July • Expect to have 107 catalogers in Pilot by September

  11. System implications of expansion • BIBFRAME to MARC conversion must be implemented and by fall • MARC created from BIBFRAME must be vetted in the community • MARC duplicates data • Want to keep URIs, even at the subfield level in some cases • BIBFRAME has more non-Latin script data, less transliteration • Title authorities are a special issue

  12. Thanks • And now over to hear about the LD4 Sinopia editor system
