Summary
A new data model for Arden Syntax standardizes database linkages and adds object-oriented features. This facilitates knowledge transfer while maintaining backward compatibility for existing Arden knowledge bases.
Area of Science:
- Health Informatics
- Clinical Knowledge Representation
Background:
- Arden Syntax is a Health Level Seven (HL7) standard for encoding computable knowledge.
- Current Arden knowledge bases (KB) lack standard database linkages, hindering knowledge dissemination.
- The HL7 Reference Information Model (RIM) is object-oriented, posing incompatibility with Arden's data model and risking loss of investment in existing KBs.
Purpose of the Study:
- To define a novel data model for Arden Syntax.
- The model aims to standardize database linkages and incorporate object-oriented features.
- Crucially, the model must maintain backward compatibility with existing Arden KBs.
Main Methods:
- Identified HL7 RIM objects suitable for standard database query schemas.
- Proposed extensions to Arden Syntax to support the new object-oriented data model.
- Included mechanisms for object manipulation within the proposed Arden extensions.
Main Results:
- A data model was defined that standardizes database linkages.
- The model introduces object-oriented constructs into Arden Syntax.
- This approach ensures backward compatibility is maintained.
Conclusions:
- The proposed data model facilitates knowledge transfer by standardizing database linkages.
- Introduction of object-oriented constructs enhances Arden Syntax's capabilities.
- Backward compatibility is preserved, protecting investments in existing Arden knowledge bases.
