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.
