  8. Why LOD? 8

  9. Motivation • Use of international and cross-domain webstandards leads to • Increased discoverability • Multiple usabilityofonedataset • Maximizedinteroperability & re-usability • Flexibledata model • Things youcan‘tsayabout traditional librarydata… 9

  10. Expected ROI • Synergy effects through standardization of technology stack: • Quantitative: saved resources • Qualitative: improved services 10

  11. hbz LOD activities 11

  13. lobid.org 13

  14. Technology stack • Data: exports from legacy systems & LOD dumps • Triple Store: 4store • Search engine: elasticsearch • RDF browser: Phresnel • Read news on our hbz LOD blog 14

  15. lobid-organisations • RDF descriptions for more than 40k international organisations • Data sources: German ISIL registry & MARC Organization Code database • Not (yet) openly licensed 15
