Abstract
In a conceptual schema that includes specializations and generalizations, and that allows multiple classification, an entity may be, at a given time, instance of one or more entity types. We call type configuration of an entity the set of entity types of which it is instance at some time. In this paper, we characterize the set of valid type configurations, taking into account the constraints defined by specializations and generalizations. We also analyze the problem of determining the valid evol...
