We compare various classes of Petri net languages. We present a new constructive proof of the equivalence, from the point of view of descriptive power, of “general” Petri nets and “restricted” Petri nets (no multiple arcs nor self-loops are allowed in the latter class). We also comment on the descriptive power of Petri nets versus that of finitely recursive processes.
