Build a model from OCEL data

About OCEL data​

OCEL 2.0 (Object-Centric Event Log) is a data structure for processes involving multiple objects. Unlike traditional single-case event logs, it centers on events and records the multiple object instances related to each event, representing intersecting and collaborative business behavior.
In traditional event logs, an event belongs to one case. Relationships between objects must be represented indirectly through splitting, duplication, or additional fields. For multi-object processes, this can flatten relationships, weaken meaning, and simplify the process into a single perspective that poorly captures dependencies, hierarchies, and collaboration. OCEL addresses this through explicit modeling of objects and their relationships.
OCEL data typically includes four core information categories:

  • Events, such as event ID, activity name, and timestamp.
  • Objects, such as object type and object instance ID.
  • Event-object relationships, identifying the objects involved in an event.
  • Object-object relationships, describing ownership, associations, or dependencies between objects.

Example:


Together, these categories describe what happened, which objects were involved, and how the objects relate, providing a structured basis for multi-object modeling and analysis.

❶   Statistics: object and event type counts, objects with related events, and events with related objects.
❷   Object-object relationships: object types associated with each object type. The number is the count of objects of that type that have related events.
❸   Event-object relationships: object types associated with each event type. The number is the count of events of that type that have related objects.
