Public Data Marketplaces and Initiatives

In 2011 European Commissioner Neelie Kroes put up a proposal to open up Europe’s Public Data for everyone to use. Neelie Kroes is a strong supporter of the use of public datasets and she called governments to put online datasets that were created with public money. Also the United Stated sees many chances for public data. Obama launched a big data initiative worth $ 200 million in 2012 to investigate the big data opportunities and technologies.

Due to these initiatives, public datasets are becoming more widely available for organisations and that thrives innovation and new solutions for (unknown) problems in the world. More and more private initiative are being launched as well. These marketplaces collect public datasets and private datasets for organisations. Visitors can buy the datasets or download them for free. At some websites organisations can also sell their own datasets. Also Google and Amazon are developing big data marketplace, be it still in a relatively small scale.
