Query: Riemannian foliations with parallel or harmonic basic forms   In this paper, we consider a Riemannian foliation whose normal bundle carries
a parallel or harmonic basic form. We estimate the norm of the O'Neill tensor
in terms of the curvature data of the whole manifold. Some examples are then
given.
