Dynamic profiling with advanced validation

  • Structure: Check that all the content in the resource follows the structure from the target profile and nothing extra is present.
  • Cardinality: Check that the cardinality of all properties follows the profile (min. & max.).
  • Binding: Check that codes provided in the code/Coding/Codeable Concept types exist in the bound terminology.
  • FHIRPath: Check that all FHIRPath constraints in the profile aren’t restricted. The FHIRPath spec is extended with custom callbacks. (Full support for FHIRPath in validations)
