Modeling and Validating Spatio-Temporal Conceptual Schemas in XML Schema

In this paper, we describe a translation algorithm that maps spatio-temporal conceptual schemas into XML schemas expressed in the W3C XML Schema Language. Moreover, we extend the standard XML Schema validator with a Java library to check spatio-temporal constraints. The resulting framework allows one to validate XML documents containing spatio-temporal information with respect to spatio-temporal conceptual schemas.
