  • Growing data, scattered data pools, varying metadata schemes, different vocabularies and last but not least the babylonian syndrome
  • Hier besonders hervorheben, dass Organisationen nicht zwingend erpicht sind, Linked Data von außen zu holen (Stichwort Complience)… interessanter (Erfahrungswert) ist es, die Richtlinien für internen Gebrauch auf die Reihe zu bekommen
  • Problem: Different sources, different formats, no time Solution: By linking personal file with others and matching them to drug databases integrated views (relation between case with medication ) can be provided in a very short time

  • 5. Connecting the dots in a world of distributed systems
    • All the information to answer even complex questions is usually available
    • But: the information is scattered across different sources and not connected yet
    • Thus users/employees usually need a lot of time to connect the dots if it comes to rather complex tasks
    • We think that linked data is a proper approach to solve this common problem in a world of distributed systems

    • Linked Data technologies support data integration especially in dynamic & distributed environments
      • Large enterprises
      • Inter-Government organisations & NGOs
      • WWW
    • Linked Data (Semantic Web) technologies make conceptual models behind the data visible and explicit
