Used widely around the globe, CKAN is an open source software that enables the storage, management, provision, and use of open data as well as the display, search, and visualisation of data. Both governments and national and international companies and organisations already use CKAN to make all types of data available to the public, for example, on population sizes or water/air quality. This data is not only useful to citizens, but also to traffic and the environment. It is used to develop applications that can prevent traffic congestion, facilitate political decisions, or alert to harmful substances in the air, for example. Data and processes thus become transparent and accessible to everyone.
CKAN has become a powerful catalogue software that can be used to make data and metadata available to users in the most varied of formats and, in part, visualise the data. Ultimately, it is the users who create the added value –by developing business models based on the data, for example. Additional benefits can be achieved by linking several datasets. What’s more, CKAN can be embedded in websites or WordPress pages via plug-ins.
Important CKAN plug-ins
CKAN Google Analytics Extension
With this plug-in, Google Analytics can easily be integrated into the CKAN page to track and visualise user activities.
CKAN Harvest Extension
The Harvest Extension is primarily suited to administrative districts or large companies, for instance, which have additional lower-level CKAN portals. The plug-in allows the resources stored there to also be integrated into the portal.
CKAN WordPress Extension
This plug-in integrates the CKAN page into WordPress, allowing for easy website management via the WordPress admin interface.
CKAN QA Extension
The Quality Assurance Extension provides an evaluation of the “openness” of each dataset by analysing parameters such as format to check whether the open standards are met.
This plug-in enables users to comment on datasets and discuss possible benefits with other users.
