Naming System

Naming System is a curated namespace that issues unique symbols within that namespace for the identification of concepts, people, devices, etc. It represents a “System” used within the Identifier and Coding data types.

Naming System defines a specific code system or identifier system, so that it can be noted in a registry for other systems to find and understand an identifier. The Code System resource defines the content of a code system, and also its preferred identifier. The Naming System resource identifies the existence of a code or identifier system, and its possible and preferred identifiers. The key difference between the resources is who creates and manages them – Code System resources are managed by the owner of the code system resource, who can properly define the features and content of the code system.

Naming System resources, on the other hand, are frequently defined by 3rd parties that encounter the code system in use, and need to describe the use, but do not have the authority to define the features and content. Additionally, there may be multiple authoritative Naming System resources for a code system, but there should only be one Code System resource.

Data Fields

Name Description Type Constraints
Concept_NameName of the concept in the FHIR structure.stringrequired : 1
Computer_Ready_NameA Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this.string-
TypeThe type the structure describes.string-
Dollar_RefThe "$ref" string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON value being referenced.string-
DescriptionA free text natural language description of the structure and its use.string-
ItemsThe value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value.string-
EnumThe enum is used to restrict a value to a fixed set of values. It must be an array with at least one element, where each element is unique.string-
RequiredThe value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value.string-
ConstThe value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword.string-

Concept NameComputer Ready NameTypeDollar RefDescriptionItemsEnumRequiredConst
NamingSystemresourceTypeThis is a NamingSystem resourceNamingSystem
NamingSystemid#/definitions/idThe logical id of the resource as used in the URL for the resource. Once assigned this value never changes.
NamingSystemmeta#/definitions/MetaThe 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.
NamingSystemimplicitRules#/definitions/uriA 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.
NamingSystem_implicitRules#/definitions/ElementExtensions for implicitRules
NamingSystemlanguage#/definitions/codeThe base language in which the resource is written.
NamingSystem_language#/definitions/ElementExtensions for language
NamingSystemtext#/definitions/NarrativeA 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.
NamingSystemcontainedarrayThese resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently and nor can they have their own independent transaction scope.{'$ref': '#/definitions/ResourceList'}
NamingSystemextensionarrayMay be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension there is a set of requirements that SHALL be met as part of the definition of the extension.{'$ref': '#/definitions/Extension'}
