Relational Access Control with Bivalent Permissions in a Social Web/Collaboration Architecture [PDF]

, 2013
We describe an access control model that has been implemented in the web content management framework "Deme" (which rhymes with "team"). Access control in Deme is an example of what we call "bivalent relation object access control"(BROAC). This model builds on recent work by Giunchiglia et al. on relation-based access control (RelBAC), as well as other
