  In the chirally symmetric Nambu--Jona-Lasinio model baryons are described as
chiral solitons of mesonic quark--antiquark bound states. Hyperons are
investigated in two complementary pictures: the bound state approach of Callan
and Klebanov and the collective approach of Yabu and Ando. The latter is used
to compute the strange vector form factors of the nucleon providing estimates
for the strange electric mean square radius and the strange magnetic moment of
the nucleon.
