4.11 Resource NamingSystem - Content

Vocabulary icon Work GroupMaturity Level: 2 Trial UseSecurity Category: Anonymous Compartments: Not linked to any defined compartments

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.

4.11.1 Scope and Usage

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.

4.11.2 Boundaries and Relationships

A NamingSystem resource manages identifiers of a code system or identifier system, identifier metadata (e.g. type), and limited code system or identifier system specific metadata (e.g. publisher and description). A CodeSystem resource represents a code system, its key properties, and may include the content, identifiers, and other metadata. There is known overlap between the CodeSystem and NamingSystem resource elements. However, the key differences between the resources are as follows:

  • CodeSystem resources may include the concept and property content of the code system, whereas NamingSystem resources do not. CodeSystem resources also allow identifiers to be supplemented by specific metadata. The metadata are supported with extensions.
  • NamingSystem resources allow the identifiers for code systems or identifier systems to be supplemented by metadata specific to the identifiers. For example: preferred, authoritative, and validity period.

4.11.5.1 Terminology Bindings

PathDefinitionTypeReference
NamingSystem.status

The lifecycle status of an artifact.

RequiredPublicationStatus
NamingSystem.kind

Identifies the purpose of the naming system.

RequiredNamingSystemType
NamingSystem.type

Identifies the style of unique identifier used to identify a namespace.

PreferredNamingSystemIdentifierSystemType (a valid code from identifierType icon)
NamingSystem.jurisdiction

This value set defines a base set of codes for country, country subdivision and region for indicating where a resource is intended to be used.

Note: The codes for countries and country subdivisions are taken from ISO 3166 icon while the codes for "supra-national" regions are from UN Standard country or area codes for statistical use (M49) icon.

ExtensibleJurisdictionValueSet
NamingSystem.topic

High-level categorization of the definition, used for searching, sorting, and filtering.

ExampleDefinitionTopic
NamingSystem.uniqueId.type

Identifies the style of unique identifier used to identify a namespace.

4.11.5.2 Constraints

UniqueKeyLevelLocationDescriptionExpression
img cnl-0Warning (base)Name should be usable as an identifier for the module by machine processing applications such as code generationname.exists() implies name.matches('[A-Z]([A-Za-z0-9_]){1,254}')
img nsd-1Rule (base)Root systems cannot have uuid identifierskind != 'root' or uniqueId.all(type != 'uuid')
img cnl-1Warning NamingSystem.urlURL should not contain | or # - these characters make processing canonical references problematicurl.matches('([^|#])*')
img nsd-2Rule NamingSystem.uniqueId.preferredCan't have more than one preferred identifier for a typeuniqueId.where(preferred = true).select(type).isDistinct()
img nsd-3Rule NamingSystem.uniqueId.authoritativeCan't have more than one authoritative identifier for a type/period combination (only one authoritative identifier allowed at any given point of time)uniqueId.where(authoritative = true).select(type).isDistinct().select(period).isDistinct()

4.11.5.3 Dealing with duplicate entries

In some cases, the same code or identifier system might accidentally be created more than once in a registry, for example because someone failed to check for an existing entry before adding a new one or knows the same concept with a different name. If this occurs, one of the system entries should be deleted and the remaining entry should have its uniqueId updated to include any identifiers present on the original entry (and possibly have its descriptive information modified to include additional information from the duplicate entry).

4.11.5.4 NamingSystem.url

The NamingSystem resource has a url property. The NamingSystem resource also specifies preferred identifiers for the Identifier or Code system that is being described. These are not the same thing; the url property of the NamingSystem itself identifies the registration of the system - the description itself, where as the preferred identifiers identify the system being described.

The NamingSystem.url SHOULD not be the same as a URL in the preferred identifiers list, and it would not therefore appear in a Coding.system or an Identifier.system.

4.11.6 Search Parameters

Search parameters for this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
