  • 2. 1. Scientistreads in theWeb browser2. Data-federation/-indexing
  • 3. Links are notyet operational
  • 4. GBIF DatenfederationData fromThailand?FungalCulturesCBSHerbariumMünchenInsectCollectionMfNBird dataGermanyafter Dave Remsen, GBIF, TDWG 2011Bird dataAustriaInsectCollectionNHM, UK

  • 6. Some linking (R. Page)
  • 7. Linking is usuallyDB-internal = local
  • 8. This is inefficient.
  • 9. - Stable Links- Return data
  • 10. Identifiers

  • 20. Why Linked Open Data?– Distributed Web Model• using W3C standards (xml, rdf, owl)• Machine usable data (automatic analysis & reasoning)• Web pages at same identifier (content negotiation)
  • 21. Why Linked Open Data?– Distributed Web Model• using W3C standards (xml, rdf, owl)• Machine usable data (automatic analysis & reasoning)• Web pages at same identifier (content negotiation)– Anyone can say anything about anything, anywhere• Usages that the data providers never anticipated• Third parties connect concepts between data sets• Particular needs contribute to global achievement
  • 22. Why Linked Open Data?– Distributed Web Model• using W3C standards (xml, rdf, owl)• Machine usable data (automatic analysis & reasoning)• Web pages at same identifier (content negotiation)– Anyone can say anything about anything, anywhere• Usages that the data providers never anticipated• Third parties connect concepts between data sets• Particular needs contribute to global achievement– Flexible to adapt to almost any form of data– Information managed at source plus annotated globally
  • 23. Why Linked Open Data?– Distributed Web Model• using W3C standards (xml, rdf, owl)• Machine usable data (automatic analysis & reasoning)• Web pages at same identifier (content negotiation)– Anyone can say anything about anything, anywhere• Usages that the data providers never anticipated• Third parties connect concepts between data sets• Particular needs contribute to global achievement– Flexible to adapt to almost any form of data– Information managed at source plus annotated globally– Queries and other analysis can combine arbitrary sets ofdata, anywhere and owned by anyone– Common and diverse vocabularies can be used togetherand related to each other (creativity, science!)
