  3. 3. The Open Knowledge Foundation We are a global movement to open up knowledge around the world and see it used and useful.
  4. 4. We build tools and communities to educate, empower and connect people.
  5. 5. What does open mean? A piece of content or data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and share-alike.

To utilize digital information more effectively to improve governance, the economy and research Context: ● Explosion of digital information ● Ever improving information technology For example: ● Find a better way to get to work ● Build more sustainable cities ● Spend government money more effectively and legitimately
  10. 10. Open Solution Step 1: get the data openly licensed Step 2: make it accessible - metadata, formats, portal ( Step 3: start building, linking and turning data into something more - information
  11. 11. CKAN - Quick Fact Sheet Open Source - all code on GitHub Extensible flexible componentized architecture Developer friendly Rich RESTful JSON API
  12. 12. Serves two main use cases 1. search and discoverability for re-users of data 2. data management tools for publishers
  13. 13. 1. Search and discovery Online home for data Central keyword search Facet by tags, location, format, licence, publishing department Browse by groups, keywords, publishers Standardized interface for viewing Link to datasets or data directly Previews and data exploration where possible
  14. 14. Numerous social and community features
  15. 15. Visualisation & data explorer functionality: ● Previews for many types of data ● Data API for .csv & tabular data ● Linkable URIs and ability to embed visualisations
  16. 16. Data explorer allows filtering, editing, plotting, graphing and embedding
  17. 17. Data Management for Publishers Easily store and update metadata records Workflow and approval Fine grained authorization controls Broken link reports Download and view counts
  18. 18. Add and edit dataset metadata
  19. 19. Authorisation & access control
  20. 20. Stats & analytics CKAN comes with inbuilt stats + integration with Google Analytics Includes dataset counts, download counts + reports
  21. 21. Link checker and 5 star ratings
  22. 22. Specialist Features
  23. 23. Sophisticated geospatial capabilities
  24. 24. Geo-Search: Filter by location / draw bounding box WMS previews Plotting GeoJSON / Longitude & Latitude in tabular data Support for: ● INSPIRE ● GEMINI 2.1 ● CSW ● ISO 19139
  25. 25. Harvesting and normalization Get metadata from external catalogs and endpoints CKAN will parse, validate and normalise to create metadata records that look the same to end users no matter where they came from We can currently harvest: other CKAN catalogs, CSW endpoints and WAFs serving ISO 19139 documents
  26. 26. Federation Search across catalogs in aggregator sites (such as Data Catalog Interoperability Protocol: http: //
  27. 27.
  28. 28. Multilingualism Translated by into over 18 languages Fully supports all international characters Added multilingual search, setting dataset language level, string translations using a vocabulary & more for the European Commission Open Data Portal
  29. 29. Roadmap Extending data exploration features Supporting complex workflows Better reports, analytics and notifications
  30. 30. Open Source All our code is on Github: https://github. com/okfn/ckan Open issue tracker Code contributions: https://github. com/okfn/ckan/blob/master/CONTRIBUTING. rst
