  Several aspects of hadron physics are well described by a simple 5D effective
field theory. Baryons arise in this scenario as "large" (and therefore
calculable) 5D skyrmions. We extend and refine the existing analysis of this 5D
soliton, which is fairly non-trivial due to the need of numerical methods. We
perform the complete quantization of those collective coordinates which are
relevant for computing the static observables like the nucleon form factors. We
compare the result with simple expectations about large-N_c QCD and with the
experimental data. An agreement within 30% is found.
