EIFL 2014 - Linked Open Data

  1. 1. Linked Open Data best practices for publishing, sharing, and interlinking structured data on the Web Antoine Isaac EIFL General Assembly, Nov 10, 2014
  2. 2. Linked (Open) Data – what is it? http://vimeo.com/36752317
  3. 3. http://data.bnf.fr/ark:/12148/cb13506631t
  4. 4. Data on the web, for machines http://data.bnf.fr/ark:/12148/cb13506631t
  5. 5. Typed links for machines http://data.bnf.fr/ark:/12148/cb13506631t

  12. 12. General benefits of linked data Structured data URIs and links, not just strings Good for internationalization Shareable data Fits and completes open data strategies Extensible and mashable "Open world" - anybody can add descriptive information and annotations about the same thing Standard protocols/techniques http://www.w3.org/2005/Incubator/lld/XGR-lld/
  13. 13. Benefits to researchers, students and patrons Information seekers can extract and re-mix the parts of the data they need, add own annotations Library items and data can be fully integrated into research documents and bibliographies Greater discovery and use, across library and non-library resources
  14. 14. Benefits to developers Use of standard protocols and models Web-based identifiers makes resources immediately available and up-to-date Freely mix or mash-up data from libraries with other sources
  15. 15. Modeling, linked data style Cross-community re-use of data models Models that re-use existing models Semantic Web technology allows mixing them! Collaborative, softer form of standardization
  16. 16. Benefits to librarians, archivists, curators and their institutions Pull together data from outside their direct environment Concentrate on their domain of local expertise rather than re-creating existing descriptions Less duplication of effort, lower infrastructure costs
  17. 17. Available Linked Library Data http://www.w3.org/2005/Incubator/lld/XGR-lld-vocabdataset/
  18. 18. Available Linked Open Data (well, a subset) http://lod-cloud.net/
  19. 19. Benefits to librarians, archivists, curators and their institutions Use of mainstream technologies rather than systems specific to libraries Clarification of metadata licensing Greater visibility on the web and reuse
  20. 20. Challenges and opportunities Vision works better if data is Open Some parts of the technology still in maturation Adaptation to business processes still in progress Full potential not reached yet It does not replace librarian work of creating metadata! But it makes it better focused and more valuable…
