Open, Convert, UseThe Citadel Open Data ecosystem

Page 2: Citadel technical

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

• 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!!

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

Page 6: Citadel technical

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

Page 7: Citadel technical

CSVThe Swiss army knife of open data

• simple• common• non-proprietary• easy to export (from Ecxel)• readable• …

Page 8: Citadel technical

CSVCSV 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?)

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

ODC architecture

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

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

Page 16: Citadel technical

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)

Page 17: Citadel technical

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

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

Page 21: Citadel technical

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

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

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

• 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

• 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
