FML Editor

en

The objective of the visual editor is to conceal the complexity of the FML language and facilitate rapid adaptation to it.
The graphical FML Editor incorporates the following patterns:

• Handling of any structures and data types defined in FHIR StructureDefinition format.
• Capability to create subgroups (encapsulating rules within isolated spaces).
• Capability to use FML transformers - constants and functions.
• Support for the FHIRPath language through the FML function ”evaluate”.
• Support of conditional ”when” expressions.
• Specialized support for complex data types such as Coding, Quantity, Date, and Reference.

The figure demonstrates the example of transforming the logical model to the Observation resource.
