When youâ€™re dealing with a flooding emergency in the middle of the worst drought for many years, the last thing you need is barriers to the sharing of geographical and meteorological information.
Yet thatâ€™s the situation faced by Australia. The authoritiesâ€™ response is to consider the widespread adoption of Creative Commons licences for public-sector information.
This encapsulates, to me, the most compelling argument for free data. That getting access to data helps us better solve problems; barriers to data make for a less innovative, less healthy country.
