Description of a process representation model based on a logical relationship.

Model diagram	Model characteristics
	Record the changing status of objects before and after and the relationship between objects
A process-based dynamic spatiotemporal data model [13]
	The graph model used to record and express the spatiotemporal changes with complex composition structure is effectively expressed, and the evolution process of object-event-object is recorded
Research on spatiotemporal data model based on Petri net [14]
	Record the object-event participation relationship and the active relationship between events and processes
Spatiotemporal data model based on object-event-process and its application [15]; Database model based on spatiotemporal ontology [16]
