We're working on models for representing and reasoning about security, authorization, delegation etc and find a need to represent speech acts such as one agent's assertion that it delegates a permission to another agent. An agent's obligations and permissions can be determined by reasoning from the representation of the security policy together with a set of validly signed public speech acts. Our approach is to try to use DAML to represent the FIPA communicative acts and associated parameters as well as a FIPA compliant content language. -- Tim Finin, Prof Computer Science & Electrical Eng, Director Inst. for Global Electronic Commerce, U Maryland Baltimore County, 1000 Hilltop, Baltimore MD 21250. mailto:finin@umbc.edu 410-455-3522 fax:-3969 http://umbc.edu/~finin/
