Detailed Descriptions for the elements in the StructureMap resource.

StructureMap
Element Id StructureMap
Definition

A Map of relationships between 2 structures that can be used to transform data.

Short Display A Map of relationships between 2 structures that can be used to transform data
Cardinality 0..*
Type CanonicalResource
Alternate Names Template; Profile
Summary false
Invariants
Defined on this element
cnl-0Warning 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}$')
StructureMap.url
Element Id StructureMap.url
Definition

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

Short Display Canonical identifier for this structure map, represented as a URI (globally unique)
Cardinality 1..1
Type uri
Requirements

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

Alternate Names url; authoritative-url; destination; identity
Summary true
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
Defined on this element
cnl-1Warning URL should not contain | or # - these characters make processing canonical references problematicexists() implies matches('^[^|# ]+$')
StructureMap.identifier
Element Id StructureMap.identifier
Definition

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

Short Display Additional identifier for the structure map
Note This is a business identifier, not a resource identifier (see discussion)
Cardinality 0..*
Type Identifier
Requirements

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

Summary true
Comments

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

StructureMap.version
Element Id StructureMap.version
Definition

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

Short Display Business version of the structure map
Note This is a business versionId, not a resource version id (see discussion)
Cardinality 0..1
Type string
Summary true
Comments

There may be different structure 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 structure map with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

StructureMap.versionAlgorithm[x]
Element Id StructureMap.versionAlgorithm[x]
Definition

Indicates the mechanism used to compare versions to determine which is more current.

Short Display How to compare versions
Cardinality 0..1
Terminology Binding Version Algorithm (Extensible)
Type string|Coding
[x] Note See Choice of Datatypes for further information about how to use [x]
Summary true
Comments

If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can't be successfully be determined.

StructureMap.name
Element Id StructureMap.name
Definition

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

Short Display Name for this structure map (computer friendly)
Cardinality 1..1
Type string
Requirements

Support human navigation and code generation.

Summary true
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.

Invariants

cnl-0Warning 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}$')
StructureMap.title
Element Id StructureMap.title
Definition

A short, descriptive, user-friendly title for the structure map.

Short Display Name for this structure map (human friendly)

See guidance around (not) making local changes to elements here.

StructureMap.experimental
Element Id StructureMap.experimental
Definition

Short Display For testing purposes, not real usage
Cardinality 0..1
Type boolean
Meaning if Missing If absent, this resource is treated as though it is not experimental.
Requirements

Enables experimental content to be developed following the same lifecycle that would be used for a production-level structure map.

Summary true
Comments

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

StructureMap.date
Element Id StructureMap.date
Definition

The date (and optionally time) when the structure map was last significantly changed. 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 structure map changes.

Short Display Date last changed
Cardinality 0..1
Type dateTime
Alternate Names Revision Date
Summary true
Comments

The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the structure map. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

See guidance around (not) making local changes to elements here.

StructureMap.publisher
Element Id StructureMap.publisher
Definition
