The RDF Protune Policy Editor: Enabling Users to Protect Data in the Semantic Web

A fine-grained user-aware access control to user profile data is a key requirement for sharing user profiles among applications. Policy languages like Protune can handle access restrictions very well but are too complicated to be used by non-experts. In this paper, we identify policy templates and embed them into a user interface that enables users to specify powerful access policies and makes them aware of the current and future consequences of their policies. In a user study, we proof the effectiveness of our editor.
