  A model for the description of photonuclear reactions in the multi-GeV range
is described that combines the coherent initial state interactions (shadowing)
of the incoming photon with an incoherent coupled channel description of final
state interactons of outgoing particles. Particle production itself is treated
either, at low energies, through nucleon resonance decays or, at higher
energies, through string fragmentation. The initial state nucleons can be
far-off-shell due to ground state correlations. Results are shown for
semi-inclusive meson production.
