Several FHIR configuration items use FHIRPath expressions to extract metadata values from incoming messages. FHIRPath is a path-based navigation and extraction language, similar to XPath, that is part of the FHIR standard specification published by HL7 International.
The OnBase FHIR module supports messages in JSON and XML format, and the same FHIRPath expressions can be used to extract values from messages in either format.
The following sections provide information and considerations on FHIRPath functions that are used in integrating OnBase with an external system using FHIR. This information is not intended as an exhaustive resource on FHIRPath.
Epic Integration will utilize FHIR R4 when communicating to Epic using the FHIR standard. The Epic Web Blob Pass-through solution will continue to utilize FHIR STU3.
For detailed information on FHIRPath, see the specification at http://hl7.org/fhirpath/.
