  6. 6. WhereDoesMyMoneyGo.org
  7. 7. DataJounalismHandbook.org
  8. 8. Working Groups okfn.org/wg
  9. 9. What problems are we trying to solve? 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 (ckan.org) 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

  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 publicdata.eu) Data Catalog Interoperability Protocol: http: //spec.datacatalogs.org/
