The Comprehensive Knowledge Archive Network (CKAN) is a web-based open source data management system for the storage and distribution of data, such as spreadsheets and the contents of databases. It is inspired by the package management capabilities common to open source operating systems like Linux, and is intended to be the "apt-get of Debian for data".[2]

CKAN's code base 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,[4] the Dutch National Data Register, the United States government's[5] and the Australian government's "Gov 2.0".[6] The state government of South Australia also makes government data freely available to the public on the CKAN platform.[7]

Internal technology[edit]

CKAN's back end, the part running on the Web server, is written mainly in Python. The web pages it offers to user browsers include Javascript. CKAN maintains information about the data sets to be offered to users in PostgreSQL databases. Searches are implemented by Solr. CKAN installations can be queried through Web APIs.[8]
