Abstract
This analysis has shown that there are several levels of ideas used in categories of Park-Milner processes. First and foremost, the theory of exact categories provides the fundamental structures. Second, the idea of rooted processes means one is attempting to work in a bigpointed category. As this brief analysis shows, bipointed categories have a rather weak collection of nice properties—at least known to me. Third, additive idempotence introduces considerable additional structure, and it is here that the non-unital aspects of the A-modules play an important rôle.
