Janus is an open-source multi-agent platform fully implemented in SARL (implemented with Java for its versions 1 and 2). Janus enables developers to quickly create web, enterprise and desktop multiagent-based applications. It provides a comprehensive set of features to develop, run, display and monitor multiagent-based applications. Janus-based applications can be distributed across a network. Janus could be used as an agent-oriented platform, an organizational platform, and/or an holonic platform. It also natively manages the concept of recursive agents and holons.
