Context-Based Naming in Information Bases
International Journal of Cooperative Information Systems, 1997In information bases following semantic and object-oriented data models, logical names are used for the external identification of objects. Yet the naming schemes employed are not "natural" enough and several problems often arise: logical names can be ambiguous, excessively long, unrelated to or unable to follow the changes of the environment of the ...

A RBAC-Based Policy Information Base
Sixth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'05), 2005This paper presents a framework for representing and distributing access control policies in distributed heterogeneous systems. Access control polices follow the RBAC (role based access control) model proposed by the NIST. The framework is based on the provisioning strategy defined by IETF, i.e., the RBAC information is represented in terms of a PIB ...

International Joint Conference on Autonomous Agents and Multiagent Systems, 2008Information-based agency is founded on two observations: everything in an agent's world model is uncertain, and everything that an agent communicates gives away valuable information. The agent's deliberative mechanism manages interaction using plans and strategies in the context of the relationships the agent has with other agents, and is the means by ...
