Title Hypermedata Approach: A Way to Systems Integration
Contributors
Abstract The paper provides an overview of the Hypermedata language specifically designed to support integration of heterogeneous information systems. The core of Hypermedata integration is data interchange resting upon a sufficiently complex and powerful language allowing to describe both intra- and inter-schema relationships of individual systems. The language uses declarative descriptions of data schemas, and functional expressions for constraints inside schemas and for conversion rules defining transformations of data instances un-der various schemas. Metadata describing data schemas, as well as transforma-tion specifications, is internally represented as oriented graphs. The evaluator of functional data expressions utilises lazy evaluation.
