pm4py.objects.ocpn.variants.to_alternative_format.apply(ocpn: OCPetriNet, parameters=None) → Dict[str, Any][source]#

Converts an OCPetriNet object to the alternative format as a Dict[str, Any] specified in pm4py.algo.discovery.ocel.ocpn.variants.classic. Only the essential components of the OCPetriNet are retained in the alternative format: activities, object_types, petri_nets, double_arcs_on_activity, start_activities, and end_activities.

Parameters:

  • ocpn (OCPetriNet) – The object-centric Petri net to be converted.

  • parameters (dict, optional) – Additional parameters for the conversion (not used in this implementation).

Returns:

ocpn – Alternative format representation of the object-centric Petri net.

Return type:

Dict[str, Any]

pm4py.objects.ocpn.variants.to_alternative_format.oc_marking_to_petri(oc_marking: OCMarking, pn_places: Dict[Place, Place]) → Marking[source]#

Convert an object-centric marking to a classic Petri-net Marking that contains only the places that are keys of the pn_places dictionary.

Parameters:

  • oc_marking (OCMarking) – The object-centric marking to convert.

  • pn_places (Dict[OCPetriNet.Place, PetriNet.Place]) – A mapping from object-centric Petri net places to classic Petri net places.

Returns:

Marking – A classic Petri net marking (place -> token count)

Return type:

Marking
