CKAN is a tool for managing and publishing collections of data. It is used by national and local governments, research institutions, and other organisations which collect a lot of data. With its powerful search and faceting, users can browse and find the data they need, and preview it using maps, graphs and tables - whether they are developers, journalists, researchers, NGOs, citizens or your own colleagues.
CKAN is free, open-source software, which has been developed by the Open Knowledge Foundation since 2006 and used by government and organisations around the world. Version 2.0 was released in May 2013.
