  6. 6. Linked Data is..• Machine readable (not a black box)• (Relatively) Simple• Uses Web standards• Re-usable• Interoperable• LinkableServices in SW are..
  7. 7. LINKED SERVICES
  8. 8. LINKED SERVICES APPROACHAND PRINCIPLES
  9. 9. Linked Services Principles• Services described as Linked Data– Inputs, outputs, functionality, etc is described using RDF(S) andusing existing vocabularies• Consume and produce RDF– Applications may contain ‘standard services’ too• Process layer on top of the Web of Data

  39. 39. Summary (1/2)• As for Linked Data desirable for application componentsto be:–Have machine-readable descriptions based on Webstandards–Discoverable–Re-usable–Interoperable–Linkable• Computing systems now associated with multipleparadigms– Community led Open Source Software initiatives– SOA, Service Marketplaces– Cloud
  40. 40. Summary (2/2)• Some efforts to leverage semantics and Linked Data tosupport interoperability, discovery, linking– Linked Services– Linked USDL for Service Marketplaces– Linked Open Software Source– Semantics in Clouds• Wider reflections on the relationship between LinkedData and current computing system paradigms wouldbenefit all associated communities
