This Code system is used in the following value sets:

How data is copied/created.

This code system defines the following codes:

create createcreate(type : string) - type is passed through to the application on the standard API, and must be known by it.
copy copycopy(source).
truncate truncatetruncate(source, length) - source must be stringy type.
escape escapeescape(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 castcast(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 appendappend(source...) - source is element or string.
translate translatetranslate(source, uri_of_map) - use the translate operation.
reference referencereference(source : object) - return a string that references the provided tree properly.
dateOp dateOpPerform a date operation. *Parameters to be documented*.
uuid uuidGenerate a random UUID (in lowercase). No Parameters.
pointer pointerReturn the appropriate string to put in a reference that refers to the resource provided as a parameter.
evaluate evaluateExecute the supplied FHIRPath expression and use the value returned by that.
cc ccCreate a CodeableConcept. Parameters = (text) or (system. Code[, display]).
c cCreate a Coding. Parameters = (system. Code[, display]).
qty qtyCreate a quantity. Parameters = (text) or (value, unit, [system, code]) where text is the natural representation e.g. [comparator]value[space]unit.
id idCreate an identifier. Parameters = (system, value[, type]) where type is a code from the identifier type value set.
cp cpCreate 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
