    Transactional Petri Nets (TPNets) are a new class of high-level Zero-Safe Nets (ZSNs), defined as a more suitable semantic framework for UML2 activity diagrams. Indeed, they ensure reactivity and synchronization of concurrent flows triggering with their junction. Reactivity is guaranteed due to the real time massive cancellation semantics based on the definition of new dynamic enabling rules and the imposed priority among executions. Global synchronization in turn is assured thanks to non-locality principle, an outcome of exploiting atomic stable transactions. Rewriting logic is defined as the operational semantics framework of TPNets.
