  We consider all hyperon data relevant to spin and flavor structure of
hyperons. In addition to masses and magnetic moments considered as static
properties in Hyperon99 we include also relevant data from hyperon decays and
spin structure determined from deep inelastic scattering. Any theoretical model
for the hyperons with parameters to be determined from experiment should use
input from all these data. Of particular interest are new data from $\Xi^o$
decay and the polarixation of $\Lambda's$ produced in Z^o decays and deep
inelastic scattering.
