The production of vector mesons ($\\rho,\\omega,\\phi$) is described via the excitation of nucleon resonances ($R$). The theoretical framework is an extended vector meson dominance model (eVMD) for resonance decays $R\\longmapsto NV$ with arbitrary spin which is covariant and kinematically complete. The eVMD includes thereby excited vector meson states in the transition form factors. The model has successfully been applied to $\\omega$ and $\\phi$ production in $p+p$ reactions.
