HL7 Cross-Paradigm Specification: FHIRPath, Release 2 (Jira PSS-2430)

FHIRPath is a path based navigation and extraction language, somewhat like XPath. Operations are expressed in terms of the logical content of hierarchical data models, and support traversal, selection and filtering of data. Its design was influenced by the needs for path navigation, selection and formulation of invariants in both HL7 Fast Healthcare Interoperability Resources (FHIR) and HL7 Clinical Quality Language (CQL). This project will produce a new version of the FHIRPath specification, incorporating implementation and user feedback for new features, clarifications, and updates, as well as consider which trial-use content should now be considered normative.
