Marc and beyond: 3 Linked Data Choices

  1. 1. MARC and Beyond Our Three Linked Data Choices Richard Wallis Evangelist and Founder Data Liberate richard.wallis@dataliberate.com @rjw IFLA WLIC 2018 Kuala Lumpar August 26th 2018
  2. 2. Independent Consultant, Evangelist & Founder Worked With: •Google – Schema.org vocabulary, site, extensions, documentation and community •OCLC – Global library cooperative •FIBO – Financial Industry Business Ontology Group •Various Clients – Implementing/understanding Schema.org British Library — Stanford University — Europeana — NLB Singapore W3C Community Groups: •Schema Bib Extend (Chair) - Bibliographic data •Schema Architypes (Chair) - Archives •Financial Industry Business Ontology – fibo.schema.org •Tourism Structured Web Data (Co-Chair) •Schema Course Extension •Schema IoT Community •Educational & Occupational Credentials in Schema.org richard.wallis@dataliberate.com — @rjw 40+ Years – Computing 28+ Years – Cultural Heritage technology 13+ Years – Semantic Web & Linked Data
  3. 3. • 1989 The Web Conceived • 1994 1st Web-based library discovery interface • 2001 Semantic Web Introduced • 2006 Linked Data • 2011 British Library Data Model • 2011 Schema.org Launched • 2012 OCLC add Schema.org to WorldCat.org • 2012 Library of Congress launch BIBFRAME Project A bit of Linked Data HistoryA bit of Linked Data HistoryLinked Data Tim Berners-Lee

  5. 5. • Lots of great individual linked data initiatives (interoperability between them a question) • Bibframe 2.0 – ready for wider standardized adoption • Schema.org – the de facto structured data standard for the web (30% domains using it) • Potential for adding web links to MARC (Linky MARC) Library Linked DataLibrary Linked Data …… where are we now?where are we now?
  6. 6. Why? Linked Data
  7. 7. Linked DataThe Challenge of Entity Reconciliation
  8. 8. Prototyping a Linked Data Platform for Production Cataloging Workflows A project vision statement Work with our members through a foundational shift in the collaborative work of libraries, communities of practice, and end-users—dramatically improving efficiency, embracing the inclusive, diverse, and earnest OCLC membership, and empowering a new and trusted knowledge network enabled by the web. Andrew K. Pace Executive Director, Technical Research
  9. 9. #ALAAC18 Phase I Partners (Dec ’17 - Apr ‘18) • Cornell University • University of California, Davis Who Phase II Partners (!!!!) (May ‘18 – Sep ‘18) – American University – Brigham Young University – Cleveland Public Library  – Harvard University – Michigan State University – National Library of Medicine – North Carolina State University – Northwestern University – Princeton University – Smithsonian Library – Temple University – University of Minnesota – University of New Hampshire – Yale University OCLC Global Technolo- gies OCLC Research OCLC Global Product Management
  10. 10. #ALAAC18 What • Develop an Entity Ecosystem that facilitates: o Creation and editing of new entities o Connecting entities to the Web • Build a community of users who can: o Create/Curate data in the ecosystem o Imagine/propose workflow uses o Communicate easily with each other and with OCLC to iteratively improve the prototype • Provide services to: o Reconcile data o Explore the data
  11. 11. RECONCILER INDEX RECONCILIATION API BATCH Local Bibliographic and Authority Data RANKING BY EDITOR UI DUPLICATE DETECTION WORLDCAT CREATIVE WORK ASSOCIATION ENTITY ECOSYSTEM UI MINTING / EDITING API AUTHENTICATION & AUTHORIZATION ENTITY to ENTITY RELATOR External Client Applications External Client Applications
  12. 12. Entity Ecosystem • Entity Creation / Edit / Reconciliation • Research Prototype – but working with OCLC Production and OCLC Members • Building on Open Source tools • Learning and applying lessons • Vocabulary independent • Potential to become a useful tool/service plus an authoritative knowledge graph
  13. 13. What are my Library Linked Data Options? BIBFRAME 2.0 Schema.org Linky MARC Do nothing Who Wants to be a Linked Data Library
  14. 14. BIBFRAME 2.0 • Matured from 1.0 (and variations) • Not perfect but ‘good enough’ – continuing to develop • MARC Conversion specifications • Open source MARC Conversion software • Good basis for standardized Linked Data (RDF) interchange • Backed by Library of Congress - Supported by others • Introduces potential for entity-based cataloguing
  15. 15. BIBFRAME 2.0 • A Library vocabulary/ontology/standard • Not recognized outside of library and associated organisations • No real use for increasing visibility & discoverability on the general web
  16. 16. • De facto structured web data standard vocabulary • Has bibliographic extension • Shared by embedding in normal page HTML (No special data endpoint required) • Already found in 30% of web • Requested by Google and others • Used to populate Search Engine Knowledge Graphs • Acknowledged by Google to influence indexing • Driving Semantic Search, Voice Search, Local Search, etc. • Not detailed/specific enough for library cataloguing, etc. Schema.org
  17. 17. • Adding http URIs to $0 & $1 MARC subfields • Recommendation of the PCC Task Group on URIs in MARC • Consistent approach to include links to entities such as people, organisations, etc. (authorities) • Not Linked Data – but a way to preserve identified entity URIs for the future and possibly use them in user interfaces etc. Linky MARC
  18. 18. Do nothing • Wait for system suppliers to catch up • Need to keep aware of developments
  19. 19. What are my Library Linked Data Options? BIBFRAME 2.0 Schema.org Linky MARC Do nothing Who Wants to be a Linked Data Library BIBFRAME 2.0 Schema.org
