Managing the Evolution of Simple and Complex Mappings between Loosely-Coupled Systems

Abstract: Semantic standards and technologies can facilitate the management of the dependency relationships between related components. Applications at different layers must map shared information both structurally (e.g., identifying which fields map to each other in different data schemas) as well as semantically (e.g., specifying the derivation relationship between a field in one schema and one or more fields from a potentially different schema). Believing that the efficient maintenance and evolution of such mappings is as important as creating the initial mappings in the first place, we present here methodologies for maintaining both simple and semantically complex mappings that exploit the rich constructs that Semantic Web technologies offer for modelling relationships. We include a description of a reference implementation that focuses on the domain of resource managing and provisioning. Notes:
