2. Background 2 Christoph/Pohl: Publishing Aleph records as LOD hbz runs

   a union catalog on Aleph since 1999 Currently 18 M records with holdings Publishing LOD via lobid.org since 2010 Primary goal: web-integrated data for discoverability and re-usability

3. Publishing LOD from Aleph 3 Local development for exporting daily

   updates Converting Aleph XML to RDF with Metafacture Vocabularies used: DC, Bibo, FRBR core, isbd, marcrel, lobid-vocab, foaf (see list here) LOD exposed in different ways: HTML/RDFa and content negotiation via lobid.org Full dumps: http://datahub.io/dataset/lobid-resources Triple store with SPARQL endpoint Web-API: http://api.lobid.org Christoph/Pohl: Publishing Aleph records as LOD

4. lobid API 4 Enables powerful reuse options of LOD, e.g.:

   Mash-Ups Auto-suggest for cataloging and searching lobid.org frontend will soon run on the lobid API (until now based on triple store) API complemented by data dumps & SPARQL endpoint Also exposed via API: authority data from ISIL registries & German Integrated Auhtority File Christoph/Pohl: Publishing Aleph records as LOD

5. Technology stack 5 Christoph/Pohl: Publishing Aleph records as LOD

6. Live demonstration 6 http://api.lobid.org Christoph/Pohl: Publishing Aleph records as LOD

7. Outlook 7 Switch lobid.org to API backend Add more data

   from GND Integrate data from Cultural Heritage Organizations vocabulary Implement the web & search interface for the North Rhine-Westphalian Bibliography based on the lobid API Christoph/Pohl: Publishing Aleph records as LOD

8. What should Ex Libris do? 8 Provide interfaces for legacy

   and future systems Push interface (event driven => real time) Use open standards for interfaces Interfaces not limited to catalog data but for all data (e.g. statistics, user data) in open formats Christoph/Pohl: Publishing Aleph records as LOD
