Building an editable, versionized LOD service for library data

  1. 1. Building an editable,versionized LOD service for library data May, 16th 2012 ELAG 2012, Palma de Mallorca Felix Ostrowski & Adrian Pohl
  2. 2. Agenda lobid.org Fresnel Display Vocabulary for RDF Implementation Vision
  3. 3. lobid.org
  4. 4. Why LOD? - Motivation LOD as ideal basis for distributed cooperative cataloging Use of international and cross-domain web standards leads to  Increased discoverability  Multiple usability of one dataset  Maximized interoperability & re-usability  Flexible data model Expected ROI: Synergy effects through standardization of technology stack
  5. 5. lobid.org Experimental LOD service Launched in 2010 Two subservices  lobid-organisations  lobid-resources Continuously improved
  6. 6. lobid-organisations Motivation: the need of URIs for libraries RDF representations of more than 40k international organisations Data sources: German ISIL registry & MARC Organization Code database Not (yet) openly licensed
  7. 7. lobid-resources lobid.resources is the LOD interface for open data from the hbz union catalog Public Domain: licensed under CC0 Currently more than 10 M records Links to other library LOD services (GND, DDC...) and to Dbpedia See also http://thedatahub.org/dataset/lobid-resources
  8. 8. Problems Data is produced in legacy systems & added via dumps Data isnt up-to-date Data cant be improved in lobid.org and fed back to legacy system
  9. 9. Vision: Building a service that... is based on Linked Data standards, supports producing/editing RDF, supports re-use of data from the LOD cloud, supports versioning, pushes changes (create, update, delete) in real time.
