Abstract
We define temporal extensions to a uniform, behavioral and functional object model by providing an extensible set of structural and behavioral abstractions to model various notions of time for different applications. We discuss the temporal semantics of inheritance by defining a lifespan behavior on objects in a collection. Finally, we give an elaborative example and show that temporal objects can be queried without adding any extra construct to the underlying query language.
