(eng): Core functions of a distributions from regular statistical families, called Johnson Families, are modifications of the well known score functions. $L_2$ distance of core functions of arbitrary distributions from Johnson families is used to define a core divergence of distributions. It almost coincides with the Kullback divergence when the deviation of parameters is small, and in the cases of heavy-tailed distributions is less sensitive to large deviations of parameters.
