Linked Data Prototype Outcomes

1. Explore Linked Data Prototype Outcomes Entity Ecosystem Mint Relate Nathan B. Putnam Director, Metadata Quality, OCLC PCC Operations Committee Meeting May 2, 2019 Load Reconcile Retrieve

2. Review of the pilot • A.k.a. Project Passage • Ran from December 2017 through September 2018 • 16 OCLC Member libraries participated • The objective was to evaluate a framework for reconciling,creating, and managing bibliographic and authority data as linked data entities and relationships • The pilot Wikibase instance included 1.2M entities, mostly data representing overlaps between Wikidata, VIAF, and WorldCat

3. Prototype participants • American University • Brigham Young University • Cleveland Public Library • Cornell University Library • Harvard University • Michigan State University • National Library of Medicine • North Carolina State University • Northwestern University • Princeton University • Smithsonian Library • Temple University • UC Davis Library • University of Minnesota • University of New Hampshire • Yale University

4. Prototype goals • Develop an entity ecosystem that facilitated… • Creation and editing of new entities • Connecting entities to the Web • Build a community of users who could.. • Create/Curate data in the ecosystem • Imagine/propose workflow uses • Provide services to.. • Reconcile data • Explore the data

5. Information for disambiguation Occupation, place of birth, place of death, type, spouse, child, etc. Identifiers for ISNI, FAST, LCNAF, and Wikidata

8. Partner case studies Postcard showing Princess Maria Josepha of Saxony in a nursing uniform (image source) Map of the town of Concord, Middlesex County, Mass.: surveyed by authority of the town by H.F. Walling, 1852 (image source) A digitized image of a poster for an Everly Brothers concert in Glenwood, Minnesota in 1965 (image source)

9. Partner case studies Digital image of a map, Harvard Library The map includes natural features, man-made structures, names of landowners, roads, and district boundaries. Issues discussed: digitized maps, geospatial data, conventions of older maps, fingerprint data (what’s useful and what isn’t), new ways of describing that wasn’t handled well or at all in MARC Postcard showing Princess Maria Josepha of Saxony in a nursing uniform (image source) Map of the town of Concord, Middlesex County, Mass.: surveyed by authority of the town by H.F.

10. Partner case studies Digital image of a poster and a postcard, University of Minnesota, National Library of Medicine Issues discussed: digitized images, fingerprint data (issues in disambiguation), creation of statements for objects, building context for interpretation, new ways of describing that wasn’t handled well or at all in MARC Postcard showing Princess Maria Josepha of Saxony in a nursing uniform (image source) Map of the town of Concord, Middlesex County, Mass.: surveyed by authority of the town by H.F.

11. Reflections and perspectives • Transitioning from records to graphs – paradigm shift • New tasks • Task that will likely become obsolete • What’s still necessary • Reinventing crowd-sourcing • Statement provenance • Balancing quality with anyone can say anything • New tools (to us) for managing quality

12. Learning, creating, amplifying • Surge in Wikidata across the community • PCC and LD4 activities • OCLC’s activities, fostering ties between library and Wikimedia communities • Connecting Wikipedia and VIAF • Libraries Leverage Wikimedia training program • Collaborations for introducing Wikidatato librarians

13. Linked data activities Full report will be released soon and available at oc.lc/linked-data
