Abstract
The Agent Reputation and Trust (ART) Testbed initiative was launched with the goal of establishing a testbed for agent reputation- and trust-related technologies. This initiative has lead to the delivery of a flexible/modular prototype platform to the community. After two years and four successful competitions, several issues have arisen that require some attention to maintain the focus of the testbed as a research oriented tool as well as the interest of the participants. This paper presents these issues and suggests some possible modifications that we think can improve the testbed.
