CKAN is currently used by governments and organizations worldwide to power both official and community data portals. CKAN was developed by the non-profit Open Knowledge Foundation and is today overseen and managed by the CKAN Association.
CKAN uses its internal model to store metadata about the different records, and presents it on a web interface that allows users to browse and search this metadata. It also offers a powerful API that allows third-party applications and services to be built around it.
Get in touch with one of the CKAN Association members in your region if you would like to learn more about the project.
