XML Enabled Metamodeling and Tools for Cooperative Information Systems

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