Mapping Engine
Mapping of knowledge from one domain (the base) into another (the target). The structure-mapping engine, or SME, is a computer simulation of the analogy and similarity comparisons.

Structure mapping theory is based on the systematicity principle, which states that connected knowledge is preferred over independent facts. Therefore, the structure mapping engine should ignore isolated source-target mappings unless they are part of a bigger structure. The SME should map objects that are related to knowledge that has already been mapped.

The theory also requires that mappings be done one-to-one, which means that no part of the source description can map to more than one item in the target and no part of the target description can be mapped to more than one part of the source. The theory also requires that if a match maps subject to target then the arguments of subject and target must also be mapped. If both these conditions are met, the mapping is said to be "structurally consistent."

Orion Health’s Rhapsody™ Integration Engine has been specifically designed to meet the present and future needs of health integration. Rhapsody manages and streamlines message exchange between hospital applications, databases and external systems.

Rhapsody's Message Mapping tools provide a clear graphical interface to allow rapid mapping of data between systems with different data formats. Mapping code is automatically generated by dragging a field from one message format to a field in the output format. The generated code can be modified for full flexibility, and an integrated debugger allows effortless testing and configuration of the mapping.

The Rhapsody Mapper supports EDI,XML and custom schemas, providing support for almost any specification, including Health Level 7 (HL7) versions 2 (EDI) and 3 (XML).
