CKAN
The Comprehensive Knowledge Archive Network (CKAN) is an open-source open data portal for the storage and distribution of open data. Initially inspired by the package management capabilities of Debian Linux,[2] CKAN has developed into a powerful data catalogue system that is mainly used by public institutions seeking to share their data with the general public.
Rufus Pollock developed its first version in 2005-2006. Since its inception, CKAN has evolved and is the leading[citation needed] open data platform software in the world, used by governments including the US and UK, to publish millions of public datasets.
CKAN's codebase is maintained by the Open Knowledge Foundation. The system is used both as a public platform on Datahub[3] and in various government data catalogues, such as the UK's data.gov.uk,[4] the Dutch National Data Register,[5] the United States government's Data.gov[6] and the Australian government's "Gov 2.0".[7] The state government of South Australia also makes government data freely available to the public on the CKAN platform.[8] The Italian government makes available the open data of the Data & Analytics Framework on the CKAN platform.[9]
