Query: Phenomenological hadron form factors: shape and relativity   The use of relativistic quark models with simple parametric wave functions
for the understanding of the electromagnetic structure of nucleons together
with their electromagnetic transition to resonances is discussed. The
implications of relativity in the different ways it can be implemented in a
simple model are studied together with the role played by mixed symmetry
s-state and D-state deformations of the rest frame wave functions of the
nucleon and Delta resonance.
