it is easy to exhibit the right D-module module even in cases without any finiteness condition. If we want to proceed in a coordinate-free way, one needs to use some finiteness hypotheses, the relative duality formalism and co-stratifications. If we are working in nonzero characteristic, things are much more subtle. This is due to the fact that, in that case, the ring D of differential operators is the enveloping algebra of the Lie-Rinehart algebra of derivations. In characteristic zero and under smoothness conditions, it is very easy to describe the D-module structure on the module of top differential forms: it is enough to start with the action of derivations by means of the opposite of the Lie derivative, and check that is is compatible with Lie brackets and Leibniz rule, and it is linear over the ring of functions.
