Detailed Descriptions

Extension
ShortAnatomical collection site
Definition

Anatomical location from which the specimen was collected (if subject is a patient). This is the target site. This element is not used for environmental specimens.

Cardinality0..1
Comments

Specimen.collection.bodySite maps to R4 Specimen.collection.bodySite. So is mapped as Equivalent.

ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1
Constraints
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
  • ext-1: Must have either extensions or value[x], not both
    extension.exists() != value.exists()
Mappings
  • rim: n/a
  • rim: N/A
Extension.id
ShortUnique id for inter-element referencing
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Cardinality0..1
Typestring
Mappings
  • rim: n/a
Extension.extension
ShortAdditional content defined by implementations
Definition

May 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.

Comments

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.
