Query: The dynamical hierarchy for Roelcke precompact Polish groups   We study several distinguished function algebras on a Polish group $G$, under
the assumption that $G$ is Roelcke precompact. We do this by means of the
model-theoretic translation initiated by Ben Yaacov and Tsankov: we investigate
the dynamics of $\aleph_0$-categorical metric structures under the action of
their automorphism group. We show that, in this context, every strongly
uniformly continuous function (in particular, every Asplund function) is weakly
almost periodic. We also point out the correspondence between tame functions
and NIP formulas, deducing that the isometry group of the Urysohn sphere is
$\Tame\cap\UC$-trivial.
