  • 7. Open SolutionStep 1: get the data openly licensedStep 2: make it accessible - metadata,formats, portal (ckan.org)Step 3: start building, linking and turning datainto something more - information
  • 8. CKAN at a glanceMetadata catalogData management platformOpen Source - everything developed on GitHubFree community and paid support availableExtensible flexible componentized architectureDeveloper friendlyRich JSON APIInteroperable

  • 10. 1. Discoverability
  • 11. Search and discoveryOnline home for dataCentral keyword searchFacet by tags, location, format, licence...Browse by groups, keywords, publishersLink to datasets or data directlyPreviews and data exploration
  • 12. Data explorer allows filtering, editing,plotting, graphing and embedding
  • 13. 2. Interoperability
  • 14. Harvesting and normalizationGet metadata from external catalogs andendpointsCKAN will parse, validate and normalise tocreate metadata records that look the same toend users no matter where they came fromWe can currently harvest: other CKANcatalogs, CSW endpoints and WAFs servingISO 19139 documents + others
  • 15. Used by governments, organizationsand communities around the world
  • 16. ckan.org/instances/
  • 17. More generally: federationSearch across numerous different catalogs inaggregator sites (such as publicdata.eu)Data Catalog Interoperability Protocol: http://spec.datacatalogs.org/
