 OpenData explains simply. Every second, we create huge amounts of data. Some see just a lot of numbers. At the same time, the data represents our daily experiences. Doctors' visits, commutes, weather conditions, and even how many parking tickets have been issued on our street. Most of the data is stored in ways which make it inaccessible, whereas some information means a huge opportunity. With OpenData, we can use these numbers and learn from them together. Is there any connection between rainfall and doctors' appointments, or between commute routes and parking tickets? Using OpenData, we have a chance to find out. Thanks to OpenData, entrepreneurs can find new ways to develop their businesses. Scientists get a better understanding of our world, while citizens and politicians can make more informed decisions. Like with England's project, where does my money go? Showing people where their taxes get spent. Anyone can combine OpenData with private data. Should you discover something interesting or create new data that you want to share, you can do so using tools such as WikiData. There are countless benefits to making information more accessible. Some of the data that is free to access today by rights is stored in places that make it in practice almost inaccessible. OpenData aims to change this. With standards for handling, storing, and accessing data, we can avoid these problems. Furthermore, data owners need to take privacy aspects into account. They have to ensure that all open data has been made anonymous and that no one's privacy is threatened. There has never been more data any time in our history than today, so why not benefit from it together by turning numbers into OpenData?
