  Based on the cosmological principle only, the method of describing the
evolution of the Universe, called cosmography, is in fact a kinematics of
cosmological expansion. The effectiveness of cosmography lies in the fact that
it allows, based on the results of observations, to perform a rigid selection
of models that do not contradict the cosmological principle. It is important
that the introduction of new components (dark matter, dark energy or even more
mysterious entities) will not affect the relationship between the kinematic
characteristics (cosmographic parameters) This paper shows that within the
framework of cosmography the parameters of any model that satisfies the
cosmological principle (the universe is homogeneous and isotropic on large
scale), can be expressed through cosmographic parameters. The proposed approach
to finding the parameters of cosmological models has many advantages. Emphasize
that all the obtained results are accurate, since they follow from identical
transformations. The procedure can be generalized to the case of models with
interaction between components.
