ckanext-resourceauthorizer is a CKAN extension that enables ACL-based permission control at the resource level. CKAN natively only supports role-based access permission at the dataset level. This extension lets users specify who (users or organizations) can or cannot access a certain resource. Access permission for an organization affects all its members. User-level permissions take priority over organization-level ones. Allowing access to a resource also grants access to the parent dataset metadata. Developed by ETRI (Electronics and Telecommunications Research Institute, Korea) as part of an Advanced Open Data Distribution Platform project funded by the Korean government (MSIT/IITP).
