  • Outcome: First specification of extension to SKOS, for representing classification hierarchies in RDF. Turtle file and skeleton draft for Linked Data vocabulary focusing on discovery aspect of DDI data.
  • DDI vocabulary:
  • XKOS vocabulary:
  • Other participants, e.g., Richard Cyganiak (DERI), Arofan Gregory (SDMX, DDI), Joachim Wackerow, Heiko Paulheim
  • Great group of very interesting people (statisticians, social scientists, computer scientists). Dagstuhl working atmosphere, even though no official Dagstuhl seminar but Leibniz institute workshop.
  • Micro-data from the social sciences may be interesting from a data integration point of view. Large amounts of heterogeneous data to be integrated with other statistics (e.g., from sensors). Much benefit in reuse and for analysis.
