The electromagnetic production of kaon-hyperon on the nucleon has been studied by means of a diagrammatic technique. All important resonances listed by the Particle Data Group up to spin 5/2 are included in this analysis. To extract the unknown coupling constants the new data from CLAS, SAPHIR, LEPS, and GRAAL collaborations have been used. In this paper we report on the preliminary results of this analysis. The available elementary model along with the modern nuclear wave functions have been used to analyze the process of photoas well as electroproduction of the hypertriton off the 3He. In this analysis we found that a proper treatment of Fermi motion is essential for describing the process, whereas the few available experimental data favor the assumption that the initial nucleon is off-shell and the final hyperon is on-shell. The influence of the higher partial waves in this process is also investigated. We also discuss the prospect of investigating kaon production off 4He.
