This Code system is used in the following value sets:

4.3.14.321.1 Content

4.3.14.321.2 StructureMapTransform

How data is copied/created.

This code system http://hl7.org/fhir/map-transform defines the following codes:

Code Display Definition
create create create(type : string) - type is passed through to the application on the standard API, and must be known by it.
copy copy copy(source).
truncate truncate truncate(source, length) - source must be stringy type.
escape escape escape(source, fmt1, fmt2) - change source from one kind of escaping to another (plain, java, xml, json). note that this is for when the string itself is escaped.
cast cast cast(source, type?) - case source from one type to another. target type can be left as implicit if there is one and only one target type known.
append append append(source...) - source is element or string.
translate translate translate(source, uri_of_map) - use the translate operation.
reference reference reference(source : object) - return a string that references the provided tree properly.
dateOp dateOp Perform a date operation. *Parameters to be documented*.
uuid uuid Generate a random UUID (in lowercase). No Parameters.
pointer pointer Return the appropriate string to put in a reference that refers to the resource provided as a parameter.
evaluate evaluate Execute the supplied FHIRPath expression and use the value returned by that.
cc cc Create a CodeableConcept. Parameters = (text) or (system. Code[, display]).
c c Create a Coding. Parameters = (system. Code[, display]).
qty qty Create a quantity. Parameters = (text) or (value, unit, [system, code]) where text is the natural representation e.g. [comparator]value[space]unit.
id id Create an identifier. Parameters = (system, value[, type]) where type is a code from the identifier type value set.
cp cp Create a contact details. Parameters = (value) or (system, value). If no system is provided, the system should be inferred from the content of the value.

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
