  1. 1. Open, Convert, Use The Citadel Open Data ecosystem
  2. 2. What is Citadel? • Citadel is a project co-funded by the EC – – – – – To create a common European open data ecosystem To allow apps to be used in different cities To make it easy to open up data (for cities) To make it easy to use this data (for citizens and developers ) Not only through standards, but through easy and usable tools as well Open Convert Use
  3. 3. Open • Many governments are opening up data • Citadel focuses on cities – Strong links with local community – But often lack in ICT budgets or know how (small cities) – Strong demand for Open Data!!
  4. 4. Benefits • Inform – Allergies? – Make it visible which trees will need to be cut soon – Remarkable trees • Engage citizens to identify risks, diseases • Crowd-source the information in a timely manner • Fun
  5. 5. What took us so long? • • • • We don’t check each tree every week We don’t want to provide data that is inaccurate We don’t have the exact geo-location for every tree. We don’t know what the best format is to do so
  6. 6. CSV The Swiss army knife of open data • • • • • • simple common non-proprietary easy to export (from Ecxel) readable …
  7. 7. CSV CSV doesn’t always cut it • Different delimiters (tabs, semicolons, commas) – “F. Mercury; musician” ≠ “F. Mercury”; “Musician” • • • • Encoding hell (Greek characters?) Different line endings on different operating systems Often has markup, subtitles, etc… No semantics (which column names are used in France?)

  9. 9. Open Convert Use
  10. 10. Platform concept • Open – Anyone can do it: publishing Excel files is a good start • Convert – Converter tools transform and publish CSV/Excel files (the majority of datasets) as “live” JSON files • Use – The App Generator Tool allows you to immediately use selected datasets
  11. 11. ODC architecture
  12. 12. Converter development • Version 1: on-line PHP – Test concept with partners and cities – Quick & dirty, but very simple to understand • Version 2: off-line Java – More complex semantic functions – More stable development, possible batch use • Version 3: on-line Java – Anytime, anywhere
  13. 13. Demo Converter Data Days 2014, Ghent, 18 Feb 2014
  14. 14. Interaction with Cities • Enthusiastic reaction (we got something right) – 16 datasets converted over winter holidays • Empowering civil servants as co-designers – Experimenting with prototypes, betas • Motivating for data quality – Seeing the process end-to-end
  15. 15. Ecosystem development • Converter enhancements – Adaptations to convert other datasets • New templates – New templates can be developed for different data structures (eg socio-economic data) • Dataset enhancements – “Rich” datasets (eg containing links in text fields) can link to external functionalities (ie reservations)
  16. 16. Next Steps • Mobile access – Integration with AGT for on-the-fly conversions • Support on-going day-to-day use – Save semantic mappings for re-use – Support batch processing – Integrate with AGT dataset listings • Continue co-design with pilots
  17. 17. Open Convert Use
  18. 18. Citadel lifecycle Open Convert Data Days 2014, Ghent, 18 Feb 2014 Use
  19. 19. Data (re-)use • Thousands of datasets are published every day – by public and private sources – in different formats – in many different domains • Is there any value in publishing them? • Is it worth the effort/cost? • How are they used? Data Days 2014, Ghent, 18 Feb 2014
  20. 20. Citadel approach • Make it easy to publish data • Make it easy for people to use data • Quick and simple apps – Increase the citizens’ innovation potential – Demonstrate the value of the dataset – Apps that can be used in different cities Data Days 2014, Ghent, 18 Feb 2014
  21. 21. How this is achieved • Mobile application templates (for different types of data) – – – – – Parking Events in the city Points of Interest in the city Crowd-sourcing Information Environmental Data • Application Generation Tool – 4 steps to create an app • Citadel Hub – Documentation, resources, discussion forum Data Days 2014, Ghent, 18 Feb 2014
  22. 22. Citadel Mobile Application Templates • Common template features: – HTML5, jQuery mobile, php ( + mysql) – Datasets in common JSON format • Environmental uses Xively feeds – 'Near-me' functionality using HTML5 geo-location feature – Map and list views – Category based filtering • All categories loaded dynamically – Back end functionality for storage Data Days 2014, Ghent, 18 Feb 2014
  23. 23. Parking places • Information about the parking lots in a city • List of total/available parking places • List of places for disabled's people vehicles • Variation: On-Street parking Data Days 2014, Ghent, 18 Feb 2014
  24. 24. Events in the city • Different event categories: festivals, exhibitions, presentations, etc. • Detailed description of each event: time, place, fees, transportation, pictures • Filter by date • Add to favorites Data Days 2014, Ghent, 18 Feb 2014

  26. 26. User-generated PoIs or crowd-sourced information • “Add new PoI” functionality • Different categories of user-generated PoIs • Detailed description of each user-generated PoI • “Add to favourites” Data Days 2014, Ghent, 18 Feb 2014
  27. 27. Environmental data • Xively feeds • Environmental data for different locations (simulation of live feeds for Athens and Manchester). • Available sensors shown on the map • Detailed page shows environmental data for each sensor (including historical data) Data Days 2014, Ghent, 18 Feb 2014

  31. 31. In summary... • The power of open data lies, not only on publishing, but on re-using  Public administrators become aware of what data is useful or interesting for citizens  The relationship between City officials and citizens is strengthened  The innovation potential of citizens increases in a very participatory way Data Days 2014, Ghent, 18 Feb 2014
