What is FQL?

FQL is a query language that allows you to retrieve, filter and project data from any data source containing FHIR Resources. It brings the power of three existing languages together: SQL, JSON and FhirPath. It allows you to create tables and is useful for gaining insight and perform quality control.

Target path

Indicates that the reference has a particular focus in the target resource, a particular element of interest, identified by a FHIRPath statement. The FHIRPath expression is limited to a the simple subset with the additional limitation that .resolve() that is not allowed. This is a more sophisticated mechanism of referring to an element than [[[http://hl7.org/fhir/StructureDefinition/targetElement]]] but does require the system resolving the item to be able to use at least FHIRPath. If the author of the reference has the ability to ensure an id will be present on the target [[[http://hl7.org/fhir/StructureDefinition/targetElement]]] might be more widely useable.
