Replying to egourgoulhon:

There remains to implement the differential part, in particular the Schouten bracket. On the Wikipedia page, there is some warning: "There are two different versions, both rather confusingly called by the same name." Do we agree that the thing to implement is the bracket given by the second formula in that page?

Yes, we agree.

Multivector fields and their Schouten-Nijenhuis bracket are now ready (at least for review...): #23429.
