Abstract

We present an Annotation-Based Access Control model supported by a Collaboration Vocabulary (CoVoc) as a more flexible and user-centric access control approach in social platforms and shared workspaces. We present also briefly two SOA-based tools for enabling our approach: Uncle-Share is a gadget that provides annotation-based access control for bookmarks and uses CoVoc for annotating collaborative relationships. Who-With-Whom uses also CoVoc and visualizes extended social networks in order to help users to select the appropriate contacts to grant access to resources.
