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.
<strong>About the Datahub</strong>
The Datahub provides free access to many of CKAN's core features, letting you search for data, register published datasets, create and manage groups of datasets, and get updates from datasets and groups you're interested in. You can use the web interface or, if you are a programmer needing to connect the Datahub with another app, the CKAN API.
Feel free to sign up - it will only take a minute. If you haven't used CKAN before, have a look at the User Guide, and try it out at demo.ckan.org. This is a demo instance - feel free to try out creating and editing datasets and groups.
You can use CKAN Groups to create and manage collections of datasets. This could be to catalogue datasets for a particular project or team, or on a particular theme, or as a very simple way to help people find and search your own published datasets.
