Project Information
This project will create a single combined query language that meets the requirements of FHIRPath, (a graph query language proposed for use within the FHIR specification) and Clinical Quality Language (CQL), (an HL7 STU for representing clinical quality logic), and which can be profiled to more appropriately meet the specific requirements of each setting.
The project will also examine whether other query requirements can be met as part of this initiative.

Initial Alignment Proposal FHIRPath:CQL::XPath:XQuery
Project Requirements: There are numerous requirements within the FHIR specification for the use of a graph query language. These requirements overlap the requirements for Clinical Quality Language, but introduce additional requirements that are not met by CQL. This project will seek to align the specifications into a single specification.
Requirements for the graph query language are a subset of the requirements for reasoning defined in Harmonization of Health Quality Artifact Reasoning and Expression Logic plus additional requirements for use within the FHIR specification as detailed here: FHIRPath Introduction.
Meeting Information
TBD
Status
In progress.
