The results of the Nijmegen soft-core potential model are presented for the low-energy {ital YN} interactions. The {ital YN} version of the model is obtained by a straightforward extension of the {ital NN} model through the application of SU(3). The potentials are due to the dominant parts of the {pi}, {eta}, {eta}{prime}, {rho}, {omega}, {phi}, {delta}, {var epsilon}, and {ital S}{sup *} Regge trajectories. This gives the traditional one-boson-exchange potentials. In addition to these, the {ital J}=0 contributions from the tensor {ital f},{ital f}{prime},{ital A}{sub 2} and Pomeron trajectories are included in the potentials. The latter give potentials of the Gaussian type. Also the form factors from Regge poles are Gaussian, which guarantees that the potentials have a soft behavior near the origin. The multichannel Schroedinger equation is solved in configuration space for the (partially) nonlocal potentials. We work on the particle basis and include the Coulomb interaction exactly.
