ocel

ocel

OCEL 2.0–shaped exporter — returns the relational tables.

ts-shape does not write OCEL JSON or SQLite itself; users feed these DataFrames to pm4py (or any other OCEL tool) directly. The column names match the OCEL 2.0 spec verbatim, so the result maps straight onto pm4py's OCEL constructor::

t = to_event_log_ocel(log)
ocel = pm4py.objects.ocel.obj.OCEL(
    events=t.events, objects=t.objects, relations=t.relations,
    o2o=t.o2o, object_changes=t.object_changes,
)

OCEL2Tables dataclass

OCEL2Tables(
    events: DataFrame,
    objects: DataFrame,
    relations: DataFrame,
    o2o: DataFrame,
    object_changes: DataFrame,
)

The five OCEL 2.0 relational tables produced from an :class:EventLog.

to_event_log_ocel

to_event_log_ocel(eventlog: EventLog) -> OCEL2Tables

Return the OCEL 2.0 tables as an :class:OCEL2Tables bundle.

The canonical schema already uses OCEL 2.0 column names, so this is a pass-through with defensive copy() calls to prevent caller mutation.
