  1. Building an editable, versionized LOD service for library data May,

    16th 2012 ELAG 2012, Palma de Mallorca Felix Ostrowski & Adrian Pohl
  2. Agenda  lobid.org  Fresnel Display Vocabulary for RDF 

    Implementation  Vision
  3. lobid.org

  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. lobid.org  Experimental LOD service  Launched in 2010 

    Two subservices  lobid-organisations  lobid-resources  Continuously improved
  6. None
  7. 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
  8. None
  9. 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
  10. None
  11. Problems  Data is produced in legacy systems & added

    via dumps  Data isn't up-to-date  Data can't be improved in lobid.org and fed back to legacy system
  12. 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.
