Semantic mapping to simplify deployment of HL7 v3 Clinical Document Architecture.

HL7 Version 3 was developed to provide semantically reliable healthcare interoperability but has been perceived as overly complex to implement. This paper describes how semantic mapping can simplify usage of HL7 Version 3 Clinical Document Architecture (CDA) and reports on the rationale for adopting this approach in three particular use cases and lessons learned from the practical application experience. We envision a broad application of the semantic mapping approach in clinical documents, messaging and application design modelling.
