  Kaon photo- and electroproduction off the nucleon is investigated in the
framework of an isobaric model up to energies of about 1 GeV above threshold
for all six isospin channels. The hadronic coupling constants in the model are
determined by fitting to the available experimental data. We give a brief
status report on the state of these models and discuss problems to be attacked
in the future. We include hadronic form factors and show that they are
essential for a proper description of the dynamics even though their inclusion
has to be done carefully in order to preserve gauge invariance. We also
investigate the effects of the K0 electromagnetic form factors for two quark
models on the longitudinal and transverse differential cross sections. It is
found that only the reaction n(e,e'K0)\Lambda is sufficiently sensitive to
extract the K0 form factor.
