Zusammenfassung The notion of nondeterministic and deterministic processes based on occurrence nets is an essential concept to capture the non-sequential truly concurrent behavior of Petri nets. This concept is well-known for elementary nets and safe place-transition nets and has been generalized to other low-level net classes. For high-level nets, however, the standard technique to define processes is to consider them as processes of the low-level net $Flat(N)$ which is obtained from $N$ via the well-known flattening construction. This low-level notion of processes for high-level nets, however, is not really adequate, because the high-level structure using data types is completely lost. For this reason we have introduced a new notion of high-level net processes for high-level nets which captures the high-level structure. The key notion is a high-level occurrence net $K$, which generalizes the well-known notion of occurrence nets from low-level to high-level nets.
