Detailed Descriptions for the elements in the ConceptMap resource.

ConceptMap
Element IdConceptMap
Definition

A statement of relationships from one set of concepts to one or more other concepts - either concepts in code systems, or data element/data element concepts, or classes in class models.

Control1..1
TypeDomainResource
Invariants
Defined on this element
cmd-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.matches('[A-Z]([A-Za-z0-9_]){0,254}')
ConceptMap.url
Element IdConceptMap.url
Definition

An absolute URI that is used to identify this concept map 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 at which an authoritative instance of this concept map is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the concept map is stored on different servers.

Control0..1
Typeuri
Requirements

Allows the concept map to be referenced by a single globally unique identifier.

Summarytrue
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.

ConceptMap.identifier
Element IdConceptMap.identifier
Definition

A formal identifier that is used to identify this concept map when it is represented in other formats, or referenced in a specification, model, design or an instance.

NoteThis is a business identifer, not a resource identifier (see discussion)
Control0..1
TypeIdentifier
Requirements

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

Summarytrue
Comments

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

ConceptMap.version
Element IdConceptMap.version
Definition

The identifier that is used to identify this version of the concept map when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the concept map 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.

NoteThis is a business versionId, not a resource version id (see discussion)
Control0..1
Typestring
Summarytrue
Comments

There may be different concept map 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 concept map with the format [url]|[version].

ConceptMap.name
Element IdConceptMap.name
Definition

A natural language name identifying the concept map. This name should be usable as an identifier for the module by machine processing applications such as code generation.

Control0..1
Typestring
Requirements

Support human navigation and code generation.

Summarytrue
Comments

The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.

ConceptMap.experimental
Element IdConceptMap.experimental
Definition

A Boolean value to indicate that this concept map is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.

Control0..1

Summarytrue
Comments

Allows filtering of concept maps that are appropriate for use versus not.

ConceptMap.date
Element IdConceptMap.date
Definition

The date (and optionally time) when the concept map was published. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the concept map changes.

Control0..1
TypedateTime
Alternate NamesRevision Date
Summarytrue
Comments

Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the concept map. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

ConceptMap.publisher
Element IdConceptMap.publisher
Definition

Summarytrue
Comments

Usually an organization but may be an individual. The publisher (or steward) of the concept map is the organization or individual primarily responsible for the maintenance and upkeep of the concept map. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the concept map. This item SHOULD be populated unless the information is available from context.
