Summary
This study introduces a novel two-level model for interconnecting medical information systems using XML and XSD schemas. Key features like containment and cardinality were successfully mapped, enabling better data exchange in healthcare.
Area of Science:
- Health Informatics
- Computer Science
Background:
- Interconnecting diverse medical information systems remains a significant challenge.
- Legacy systems often lack standardized interfaces for modern data exchange.
Purpose of the Study:
- To present a two-part structural standard for information technology support in medical information system interconnection.
- To demonstrate the translation of abstract medical data models to practical, lower-level database formats.
Main Methods:
- Applied a two-part structural standard: Information Reference (IR) Model and Archetype Reference (AR) Model.
- Utilized XML and XSD schemas for lower-level data representation and validation.
- Developed an archetype-XSD translator tool as Protégé/OWL plugins.
- Tested the system on the MedQuery industrial interface using openEHR.
Main Results:
- Successfully mapped crucial features (Containment, Cardinality, Named references, External terminology references) to standard XSD constructs.
- Developed a validator plugin for checking external references.
- Demonstrated the viability of the archetype-XSD translation paradigm.
Conclusions:
- The proposed two-level model effectively translates abstract medical data structures into practical XSD formats for legacy systems.
- The developed tools facilitate standardized medical data exchange, improving interoperability.
