This paper outlines a generic, core temporal object model that provides support for the modeling of temporal object roles. This model draws from notions introduced in some of our previous works on temporal object modelingby providing a speci c database model that provides a conceptual modeling context for temporal object roles 3, 4, 5, 6, 9, 7, 2, 8, 10, 11]. The model achieves an integration of the abstract concepts that characterize temporal objects. The main purpose of the model is to provide a basic framework for temporal object informationmodelsand information systems. The model is based on a small number of simple \temporal" constructs and primitive \temporal" operations. The simple set of modeling constructs of this model are temporal objects and temporal mappings. A set of primitive operations is de ned on temporal objects that allows uniform viewing, de nition, insertion and manipulationof objects in temporalobject databases. A simple set of temporal constraints is ...
