Open data portals around the world have certainly provided lots of data to anybody with the skill to download a dataset. If you don’t have a particular analysis in mind, but want to develop an app to make the available data more useful, you are in luck. If one of the available datasets hits the nail on the head for a problem you want to work on, even better. However, the data that sits in open portals is there for a number of reasons. Opendatahandbook.org provides many good reasons as to why. Many data sets are the result of Freedom of Information Acts (FOIA) actions that some government leaders see as an opportunity to put up additional data.
