1.23.2.1.3 Value Set for codes in http://hl7.org/fhir/data-types

This is a value set defined by the FHIR project.

Summary

Code System URL:	http://hl7.org/fhir/data-types
Value Set URL:	http://hl7.org/fhir/vs/data-types
Definition:	The type of an element - one of the FHIR data types

Formal value Set definition : XML or JSON.

This value set defines its own codes:

This value set contains 42 concepts

1.23.2.1.3.1 DataType

The type of an element - one of the FHIR data types

This value set defines its own terms in the system http://hl7.org/fhir/data-types

Code	Definition
Address	There is a variety of postal address formats defined around the world. This format defines a superset that is the basis for all addresses around the world.
Age	A duration (length of time) with a UCUM code
Attachment	For referring to data content defined in other formats.
BackboneElement	Base definition for all elements that are defined inside a resource - but not those in a data type.
CodeableConcept	A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text.
Coding	A reference to a code defined by a terminology system.
ContactPoint	Details for All kinds of technology mediated contact points for a person or organization, including telephone, email, etc.
Count	A count of a discrete element (no unit)
Distance	A measure of distance
Duration	A length of time
Element	Base definition for all elements in a resource.
ElementDefinition	Captures constraints on each element within the resource, profile, or extension.
Extension	Optional Extensions Element - found in all resources.
HumanName	A human's name with the ability to identify parts and usage.
Identifier	A technical identifier - identifies some entity uniquely and unambiguously.
Meta	The metadata about a resource. This is content in the resource that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.
Money	An amount of money. With regard to precision, see [[X]]
Narrative	A human-readable formatted text, including images.
Period	A time period defined by a start and end date and optionally time.
Quantity	A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.
Range	A set of ordered Quantities defined by a low and high limit.
Ratio	A relationship of two Quantity values - expressed as a numerator and a denominator.
Reference	A reference from one resource to another.
SampledData	A series of measurements taken by a device, with upper and lower limits. There may be more than one dimension in the data.
Signature	An XML digital signature along with supporting context.
Timing	Specifies an event that may occur multiple times. Timing schedules are used to record when things are expected or requested to occur. The most common usage is in dosage instructions for medications. They are also used when planning care of various kinds.
base64Binary	A stream of bytes
boolean	Value of "true" or "false"
code	A string which has at least one character and no leading or trailing whitespace and where there is no whitespace other than single spaces in the contents
date	A date, or partial date (e.g. just year or year + month). There is no time zone. The format is a union of the schema types gYear, gYearMonth and date. Dates SHALL be valid dates.
dateTime	A date, date-time or partial date (e.g. just year or year + month). If hours and minutes are specified, a time zone SHALL be populated. The format is a union of the schema types gYear, gYearMonth, date and dateTime. Seconds must be provided due to schema type constraints but may be zero-filled and may be ignored. Dates SHALL be valid dates.
decimal	A rational number with implicit precision
id	Any combination of lowercase letters, numerals, "-" and ".", with a length limit of 36 characters. (This might be an integer, an unprefixed OID, UUID or any other identifier pattern that meets these constraints.) Systems SHALL send ids as lower-case but SHOULD interpret them case-insensitively.
instant	An instant in time - known at least to the second
integer	A whole number
oid	An oid represented as a URI
positiveInt	An integer with a value that is positive (e.g. >0)
string	A sequence of Unicode characters
time	A time during the day, with no date specified
unsignedInt	An integer with a value that is not negative (e.g. >= 0)
uri	String of characters used to identify a name or a resource
uuid	A UUID, represented as a URI

OIDs

Code System OID:	2.16.840.1.113883.4.642.1.3
Value Set OID:	2.16.840.1.113883.4.642.2.3
Note: these OIDs are not used in FHIR, but may be used in v3, or OID based terminology systems

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. In this scheme, some codes are under other codes, and imply that the code they are under also applies

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)

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

Comments

Additional notes about how to use the code

In addition, this page will include mappings to HL7 v2 or HL7 v3 code where these have been defined.
