p 'causally upstream or within' q iff (1) the end of p is before the end of q and (2) the execution of p exerts some causal influence over the outputs of q; i.e. if p was abolished or the outputs of p were to be modified, this would necessarily affect q.

We would like to make this disjoint with 'preceded by', but this is prohibited in OWL2
