Some basic properties of isobar models are discussed using the Saclay-Lyon,
Kaon-MAID, and H2 models and a comparison of their predictions with
experimental data is given for photo- and electroproduction of $K^+$ on the
proton and for photoproduction of $K^0$ on the deuteron in specific kinematical
regions. Results of the isobar models are also compared with the Regge-isobar
hybrid model, Regge-plus-resonance.Comment: 13 pages, 6 figures; in Proceedings of the International Conference
