We consider the cone of admissible metrics, introduce a special norm in it, prove compactness criteria, define the \"-entropy of a measure space with an admissible metric, etc. These notions and related results are applied to the theory of transformations with invariant measure; namely, we study the asymptotic properties of orbits in the cone of admissible metrics with respect to a given transformation or a group of transformations.
