# Auto-generated by /home/maestro/repos/MV2/examples/semantics/translational/regenerate_mm.py.

# Merged run-time meta-models of 'Petri Net' and 'Port' formalisms.
# An abstract 'Top'-class (superclass of everything else), and a 'generic_link'-association (which can connect everything with everything) have also been added.
