Understanding FUME Mapping Language (FLASH): A Practical Approach to FHIR Data Transformation
[FUME TO FHIR] 19 FUME Mapping Language(FLASH) - iT 邦幫忙- iThome
Summary
This article provides a technical explanation of the FUME Mapping Language, which combines JSONata and FLASH. It introduces how structure description is handled by FLASH and data manipulation is performed, demonstrating practical implementation methods for mapping data into FHIR resources.
Details
This detailed guide explores the FUME Mapping Language used in the process of transforming data into FHIR, a standard for healthcare information exchange. FUME consists of two components: JSONata and FLASH (modified from FSH), with each handling structure description or data manipulation. Key concepts covered include how to declare resource types using `InstanceOf: <type>` in FLASH, and context rules utilizing `(context element)` to retrieve values from input data. The article also compares two practical implementation patterns for handling complex input data: whether to use the composite field directly or define separate variables within the FUME mapping. By doing so, it provides specific technical knowledge on how to efficiently construct FHIR resources while maintaining the integrity of the source data provided by the sender.
