Concepts

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

Code	Definition	FHIRPath Equivalent	Copy
create	create(type : string) - type is passed through to the application on the standard API, and must be known by it.	n/a
copy	copy(source).	n/a
truncate	truncate(source, length) - source must be stringy type.	substring
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.	n/a
cast	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](http://hl7.org/fhirpath/N1/#is-type-specifier))	n/a
append	append(source...) - source is element or string.	& (String concatenation)
translate	translate(source, uri_of_map) - use the translate operation.	%terminologies.translate()
reference	reference(source : object) - return a string that references the provided tree properly.	related to resolve() but returns the string pointer
dateOp	Perform a date operation. *Parameters to be documented*.	n/a
uuid	Generate a random UUID (in lowercase). No Parameters.	n/a
pointer	Return the appropriate string to put in a reference that refers to the resource provided as a parameter.	n/a
evaluate	Execute the supplied FHIRPath expression and use the value returned by that.	n/a
cc	Create a CodeableConcept. Parameters = (text) or (system. Code[, display]).	n/a
c	Create a Coding. Parameters = (system. Code[, display]).	n/a
qty	Create a quantity. Parameters = (text) or (value, unit, [system, code]) where text is the natural representation e.g. [comparator]value[space]unit.	n/a
id	Create an identifier. Parameters = (system, value[, type]) where type is a code from the identifier type value set.	n/a
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.	n/a
