Attributes

Name

• Key: name
• Components:
  • log
  • trace
  • event
• Datatype: xs:string

Stores a generally understood name for any component type. For streams and logs, the name attribute may store the name of the process having been executed. For traces, the name attribute usually stores the case ID. For events, the name attribute represents the name of the event, e.g. the name of the executed activity represented by the event.

Instance

• Key: instance
• Components:
  • event
• Datatype: xs:string

This represents an identifier of the activity instance whose execution has generated the event. This way, multiple instances (occurrences) of the same activity can be told apart.
