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

CodeDefinitionFHIRPath EquivalentCopy

create(type : string) - type is passed through to the application on the standard API, and must be known by it.

n/abtn btn


n/abtn btn

truncate(source, length) - source must be stringy type.

substringbtn btn

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.

n/abtn btn

cast(source, type?) - cast (convert) source from one type to another. Target type can be left as implicit if there is one and only one target type known. The default namespace for the type is 'FHIR' (see FHIRPath type specifiers icon)

n/abtn btn

append(source...) - source is element or string.

& (String concatenation)btn btn

translate(source, uri_of_map) - use the translate operation.

%terminologies.translate()btn btn

reference(source : object) - return a string that references the provided tree properly.

related to resolve() but returns the string pointerbtn btn

Perform a date operation. Parameters to be documented.

n/abtn btn

Generate a random UUID (in lowercase). No Parameters.

n/abtn btn

Return the appropriate string to put in a reference that refers to the resource provided as a parameter.

n/abtn btn

Execute the supplied FHIRPath expression and use the value returned by that.

n/abtn btn

Create a CodeableConcept. Parameters = (text) or (system. Code[, display]).

n/abtn btn

Create a Coding. Parameters = (system. Code[, display]).

n/abtn btn

Create a quantity. Parameters = (text) or (value, unit, [system, code]) where text is the natural representation e.g. [comparator]value[space]unit.

n/abtn btn

Create an identifier. Parameters = (system, value[, type]) where type is a code from the identifier type value set.

n/abtn btn

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.

n/abtn btn

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
