摘要：

The recent precise measurements of the e(+)e(-) -> KSKL and e(+)e(-) -> K+K- cross sections and the hadronic spectral function of the tau(-) -> K-KS nu(tau) decay are used to extract the isoscalar and isovector electromagnetic kaon form factors and their relative phase in a model-independent way. The experimental results are compared with a fit based on the vector-meson-dominance model.
