  Non-autonomous Svinolupov-Jordan systems are considered. The integrability
criteria of such systems are associated with the existence of recursion
operators. A new non-autonomous KdV system is obtained and its recursion
operator is given for all $N$. The examples for N=2 and N=3 are studied in
detail. Some possible transformations are also discussed which map some systems
to autonomous cases.
