OpenSpending is a project that we at TaxHack really like. The underlying principle is “about Mapping the Money. The aim is to help track every (public) government and corporate financial transaction across the world and present it in useful and engaging forms for everyone from a school-child to a data geek.”
It is based on an open platform of participation and all manner of contributions are welcome. They are present at various hackdays, and the data collected is available in a central database through the OpenSpeding API.
How can OpenSpending be useful for the Tax Justice movement? The number one rule of investigative journalism – particularly with corruption and tax abuse – is to FOLLOW THE MONEY.
