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.

API
-
Project FHIR API
This is the location where you can find your resource using a FHIR client.
-
Simplifier FHIR API
The global endpoint is where users can search for all resources in Simplifier. Resources have a globally unique guid Id here.

Unregistered conflicting canonical
The canonical from this resource does not match any claim in this context and conflicts with a claim from another scope.

Canonical claims are used to verify ownership of your canonical URLs.

| Distance | I | Quantity | Element idDistance A length - a value with a unit that is a physical distance DefinitionA length - a value with a unit that is a physical distance. The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.
| |
| id | 0..1 | string | There are no (further) constraints on this element Element idDistance.id xml:id (or equivalent in JSON) Definitionunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
| |
| extension | 0..* | Extension | There are no (further) constraints on this element Element idDistance.extension 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. In order 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 is allowed to 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 Mappings

| value | Σ | 0..1 | decimal | There are no (further) constraints on this element Element idDistance.value Numerical value (with implicit precision) DefinitionThe value of the measured amount. The value includes an implicit precision in the presentation of the value. Precision is handled implicitly in almost all cases of measurement. The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books).
|
| comparator | Σ ?! | 0..1 | codeBinding | There are no (further) constraints on this element Element idDistance.comparator < | <= | >= | > - how to understand the value DefinitionHow the value should be understood and represented - whether the actual value is greater or less than the stated value due to measurement issues; e.g. if the comparator is "<" , then the real value is < stated value. Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology. This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value. If there is no comparator, then there is no modification of the value How the Quantity should be understood and represented. ?? (required)Mappings
|
| unit | Σ | 0..1 | string | There are no (further) constraints on this element Element idDistance.unit Unit representation DefinitionA human-readable form of the unit. There are many representations for units of measure and in many contexts, particular representations are fixed and required. I.e. mcg for micrograms.
|
| system | Σ I | 0..1 | uri | There are no (further) constraints on this element Element idDistance.system System that defines coded unit form DefinitionThe identification of the system that provides the coded form of the unit. Need to know the system that defines the coded form of the unit.
|
| code | Σ | 0..1 | code | There are no (further) constraints on this element Element idDistance.code Coded form of the unit DefinitionA computer processable form of the unit in some unit representation system. Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest. The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.
