DKan
DKAN is a Drupal distribution that provides a complete and integrated management solution for an open data portal, designed to have features compatible with CKAN. Its name is of course a reference to CKAN, but it is a completely independent solution although interoperability is possible. DKAN has a different approach to CKAN, because it integrates the functionality of an open data portal into an existing CMS. Datasets are treated as content, offering rich workflows.
