Making two-level standards work in legacy communication frameworks.

The research presented deals with the problem of how information technology can support the interconnection of medical information systems in practice. We apply a two-part structural standard that consists of a fixed Information Reference (IR) Model, and an Archetype Reference (AR) Model that uses the structures of the IR model. A very important problem with the real-world application of such a two-level model is that the high level (abstract) entities, structures and their connections must be somehow translated into lower level equivalents that legacy database information systems can actually use to program their standardised interface.
