    Abstract

    We show that community decisions about access control in virtual communities cannot be expressed in current trust management languages. The problem is that trust management languages such as the family of Role Based Trust Management languages (RT) are monotonic. To solve the problem we propose RT-, which adds a restricted form of negation to the standard RT language, thus admitting a controlled form of non-monotonicity. The semantics of RT- is presented in terms of the well-founded semantics for Logic Programs. An implementation of RT- is given using XSB.
