Summary
This study introduces the Connection Service (CS) for the HELIOS system, enhancing distributed health information interoperability. The proposed meta-model enables seamless message interpretation and translation, addressing semantic heterogeneity in healthcare data exchange.
Area of Science:
- Health Informatics
- Software Engineering
- Information Systems
Background:
- Interoperability is a critical challenge in distributed health information systems.
- Existing systems often struggle with diverse data formats and semantic differences.
Purpose of the Study:
- To design and implement the Connection Service (CS) component for the HELIOS medical software engineering environment.
- To address the interoperability challenges in distributed health information systems.
Main Methods:
- Development of an exchange message meta-model based on CEN TC251 recommendations.
- Creation of a message description language.
- Implementation of the Connection Service (CS) utilizing the meta-model for message interpretation and translation.
Main Results:
- The Connection Service (CS) can interpret messages in various syntaxes (e.g., EDIFACT, ASTM) and map them to application objects.
- Automated translation of messages between different syntaxes is achievable.
- The meta-model effectively manages semantic heterogeneity in health information exchange.
Conclusions:
- The proposed meta-model approach significantly contributes to managing semantic heterogeneity in health information systems.
- The Connection Service (CS) enhances interoperability within the HELIOS environment.
- This design facilitates more robust and flexible health data exchange.
