NamingSystem
Element IdNamingSystem
Definition

A curated namespace that issues unique symbols within that namespace for the identification of concepts, people, devices, etc. Represents a "System" used within the Identifier and Coding data types.

Short DisplaySystem of unique identification
Cardinality1..1
Invariants

NamingSystem.id
Element IdNamingSystem.id
Definition

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Short DisplayLogical id of this artifact
Cardinality0..1
Typeid
Comments

Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.

NamingSystem.meta
Element IdNamingSystem.meta
Definition

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

Short DisplayMetadata about the resource
Cardinality0..1
TypeMeta
Invariants
Inherited by this element
ele-1RuleAll FHIR elements must have a @value or childrenhasValue() or (children().count() > id.count())
NamingSystem.implicitRules
Element IdNamingSystem.implicitRules
Definition

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Short DisplayA set of rules under which this content was created
Cardinality0..1
Typeuri
Is Modifiertrue (Reason: This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies its meaning or interpretation)
Comments

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.

Invariants

NamingSystem.language
Element IdNamingSystem.language
Definition

The base language in which the resource is written.

Short DisplayLanguage of the resource content
Cardinality0..1
Terminology BindingIETF language tag for a human language
The codes SHALL be taken from All Languages
Typecode
Comments

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Invariants
Inherited by this element
ele-1RuleAll FHIR elements must have a @value or childrenhasValue() or (children().count() > id.count())
NamingSystem.text
Element IdNamingSystem.text
Definition

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Short DisplayText summary of the resource, for human interpretation
Cardinality0..1 This element is affected by the following invariants: dom-6
TypeNarrative
Alternate Namesnarrative, html, xhtml, display
Comments

Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

Invariants
Inherited by this element
ele-1RuleAll FHIR elements must have a @value or childrenhasValue() or (children().count() > id.count())
NamingSystem.contained
Element IdNamingSystem.contained
Definition

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

Short DisplayContained, inline Resources
Cardinality0..* This element is affected by the following invariants: dom-2, dom-4, dom-3, dom-5
TypeResource
Alternate Namesinline resources, anonymous resources, contained resources
Comments

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.

NamingSystem.modifierExtension
Element IdNamingSystem.modifierExtension
Definition

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

Short DisplayExtensions that cannot be ignored
Cardinality0..*
TypeExtension
Is Modifiertrue (Reason: Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them)
Requirements

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Alternate Namesextensions, user content
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

NamingSystem.url
Element IdNamingSystem.url
Definition

An absolute URI that is used to identify this naming system when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this naming system is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the naming system is stored on different servers.

Short DisplayCanonical identifier for this naming system, represented as a URI (globally unique)
Cardinality1..1
Typeuri
Must Supporttrue
Requirements

Allows the naming system to be referenced by a single globally unique identifier.

Comments

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

Invariants

Short DisplayAdditional identifier for the naming system (business identifier)
Cardinality0..*
TypeIdentifier
Requirements

Allows externally provided and/or usable business identifiers to be easily associated with the naming system.

Comments

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this naming system outside of FHIR, where it is not possible to use the logical URI.

Invariants
Inherited by this element
ele-1RuleAll FHIR elements must have a @value or childrenhasValue() or (children().count() > id.count())
NamingSystem.version
Element IdNamingSystem.version
Definition

The identifier that is used to identify this version of the naming system when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the naming system author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence.

Short DisplayBusiness version of the naming system
Cardinality1..1
Typestring
Must Supporttrue
Comments

There may be different naming system instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the naming system with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

Element IdNamingSystem.uniqueId.modifierExtension
Definition

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

Is Modifiertrue (Reason: Modifier extensions are expected to modify the meaning or interpretation of the element that contains them)
Requirements

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Comments

Different identifier types may be used in different types of communications (OIDs for v3, URIs for FHIR, etc.). Other includes RUIDs from v3, standard v2 code name strings, etc. Preferred identifiers for the same identifier type SHOULD NOT overlap by period.

Comments

If the value is a URI intended for use as FHIR system identifier, the URI should not contain "&quot; or "?" or "," since this makes escaping very difficult.

Definition

Identifies the period of time over which this identifier is considered appropriate to refer to the naming system. Outside of this window, the identifier might be non-deterministic.

Short DisplayWhen is identifier valid?
Cardinality0..1 This element is affected by the following invariants: nsd-3
TypePeriod
Comments

Within a registry, a given identifier should only be "active" for a single namespace at a time. (Ideally, an identifier should only ever be associated with a single namespace across all time).

The nuance of identifier deprecation is not represented with a separate element. When a determination is made that an identifier should not be used, the validity period end date is updated with the date the identifier is deemed to be deprecated. The identifier should no longer be used once the period end date is reached.
