Concepts

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

CodeDefinitionfhirpath
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)

 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
