The development of tools to support semantic resolution is a key issue in the design of heterogeneous interoperable information systems. This paper presents a methodology and a data model translator toolkit, called X-TIME, for the design and management of interoperable information systems. X-TIME combines a metamodelling approach and XML features to provide support for automated design of wrappers or semantic reconciliators. It is a flexible semantics oriented approach that takes into account several important characteristics of interoperable information systems, including extensibility and composability. Extensibility requires a translation scheme that can easily integrate new data models. Composability, which is the ability of an application to dynamically determine the data source it needs, requires on demand translation of data models. To meet these requirements, X-TIME is based on an extensible metamodel that can be used to represent meta-level semantic descriptors of existing modeling concepts.
