TuCSoN4Jason (T4Jn for short) is a Java library enabling Jason agents to exploit TuCSoN coordination services wrapped as Jason internal actions. Jason is a well-known Java-based implementation of the AgentSpeak(L) language for BDI agents. TuCSoN is Java-based middleware providing software agents with coordination as a service via programmable logic tuple spaces, called tuple centres.

By combining TuCSoN and Jason, T4Jn aims at providing MAS engineers with a full-featured MAS middleware for cognitive agents, enabling them to exploit both dimensions of agent-oriented software engineering — individual, through Jason agents; social, via TuCSoN tuple centres — in a complete and well-balanced way.
