  • Annotation-Based Access Control for e-Professionals 

    Nasirifard, Peyman; Peristeras, Vassilios (2008)
    Collaborative Working Environments (CWE) provide shared workspaces that enable eProfessionals to work together and share resources that they own. Most current shared workspaces provide coarse-grained role-based access ...
  • An Annotation-based Access Control Model and Tools for Collaborative Information Spaces 

    Nasirifard, Peyman; Peristeras, Vassilios; Decker, Stefan (2008)
    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 ...
  • Applying DAC Principles to the RDF Graph Data Model 

    Kirrane, Sabrina; Mileo, Alessandra; Decker, Stefan (2013)
    In this paper we examine how Discretionary Access Control principles, that have been successfully applied to relational and XML data, can be applied to the Resource Description Framework (RDF) graph data model. The ...
