Open Government Data
Government gathers a ton of data. Some of it is provided to the public by law.
But why do we care?
The Value of Open Data
- Transparency
- Make better decisions
- Improved efficiency/effectiveness of government
- Save the world, etc.
Man, what a burden
Open Data is a Learning Opportunity
