4.11 Resource NamingSystem - Content

Terminology Infrastructure icon Work GroupMaturity Level: 4 Trial UseSecurity Category: Anonymous Compartments: No 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

Path ValueSet Type Documentation
NamingSystem.versionAlgorithm[x] VersionAlgorithm Extensible

Indicates the mechanism used to compare versions to determine which is more current.
NamingSystem.status PublicationStatus Required

The lifecycle status of an artifact.
NamingSystem.kind NamingSystemType Required

Identifies the purpose of the naming system.
NamingSystem.type NamingSystemIdentifierSystemType (a valid code from identifierType icon) Preferred

Identifies the style of unique identifier used to identify a namespace.
NamingSystem.jurisdiction JurisdictionValueSet Extensible

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.
NamingSystem.topic DefinitionTopic Example

High-level categorization of the definition, used for searching, sorting, and filtering.
NamingSystem.uniqueId.type NamingSystemIdentifierType Required

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}$')
img nsd-1Rule (base)Root systems cannot have uuid identifierskind != 'root' or uniqueId.all(type != 'uuid')
img cnl-1Warning NamingSystem.urlURL should not contain | or # - these characters make processing canonical references problematicexists() implies matches('^[^|# ]+$')
img nsd-2Rule (base)Can't have more than one preferred identifier for a typeuniqueId.where(preferred = true).select(type).isDistinct()
img nsd-3Rule (base)Can'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.toString() & period.start.toString() & period.end.toString()).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 if they didn't recognize that their addition replicates another. If this occurs, the system publisher should be contacted for guidance.

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. See also the full list of search parameters for this resource, and check the Extensions registry for search parameters on extensions related to this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
