Semantic Web and Open Data

  1. 1. Linked Open Data Egon Willighagen (@egonwillighagen) May 2012, Maastricht, HARMONY 2012Department of Bioinformatics - BiGCaT 1
  2. 2. Open Data• Use• Mix (or convert!)• Reshare• Licenses – Creative Commons flavors, …• Waivers – CCZeroDepartment of Bioinformatics - BiGCaT 2
  3. 3. Linked Data: meaning• Why Semantic Web? – Unique identifiers: URLs (registries are redundant) – Meaning: what is glucose? What are Mad2, CDK2, Pax-5 (BioModel of the month 12/05, CCZero)?Ontologies, … – Gene Ontology – BioPortal, OLS, … – ... Department of Bioinformatics - BiGCaT 3
  4. 4. Linked Data: linking• Why Semantic Web? – Web: stand-up scientist – Linking: “Give me all models that predict something that predict glucose concentration” – “What are the chemical properties of glucose”BIOMD0000000051CCZeroDepartment of Bioinformatics - BiGCaT 4
