I want to Open Data!


Open = Freedom to Use / Re-use / Redistribuite

Open Data, what?

Geodata, Statistic, Electoral-Legal, Transport, Environment, National Law, Education,...


Open Data, why?

The Holy Trinity:Innovation, Efficiency, Transparency

Aka Jobs and Growth, Community and Governance

Open Data, how?
