In spite of the early efforts for studying Ξ resonances, we still do not have enough information on the properties of these resonances. The number of observed Ξ resonances is much smaller than the quark model predictions, and the predicted mass spectrum shows serious model-dependence. Furthermore, the spin-parity quantum numbers are not known for most observed resonances and the parity of the ground state Ξ has never been measured. In this talk, we review the issue in the Ξ spectrum and present a model for Ξ photoproduction which emphasizes the role of high-spin hyperon resonances.
