4.3.16.256.1 Content

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:

Level

A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')

Display

The 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

Definition

An explanation of the meaning of the concept
