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.

ParameterDefinition
Base StructureDefinition for ParameterDefinition Type: The parameters to the module. This collection specifies both the input and output parameters. Input parameters are provided by the caller as part of the $evaluate operation. Output parameters are included in the GuidanceResponse.

ParameterDefinition | Element | Element idParameterDefinitionShort description Definition of a parameter to a module DefinitionThe parameters to the module. This collection specifies both the input and output parameters. Input parameters are provided by the caller as part of the $evaluate operation. Output parameters are included in the GuidanceResponse. The cardinality or value of this element may be affected by these constraints: ele-1 Constraints

id | 0..1 | string | There are no (further) constraints on this element Element idParameterDefinition.idShort description Unique id for inter-element referencing DefinitionUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
| |
extension | C | 0..* | Extension | There are no (further) constraints on this element Element idParameterDefinition.extensionShort description Additional content defined by implementations Alternate namesextensions, user content DefinitionMay be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints
