Detailed Descriptions for the elements in the StructureMap resource.

StructureMap
Definition

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

Control1..1
Alternate NamesTemplate; Profile
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. This SHOULD be globally unique, and SHOULD be a literal address at which this structure map is (or will be) published.

Control1..1
Typeuri
Requirements

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

Alternate Namesurl; authoritative-url; destination; identity
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 URL SHOULD include the major version of the structure map. For more information see Technical and Business Versions.

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.

NoteThis is a business identifer, not a resource identifier (see discussion)
Control0..*
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, e.g., to identify this structure map outside of FHIR, where it is not possible to use the logical URI.

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.

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

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.

Control1..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 alpha-numeric type name to ensure that it is computable friendly.

StructureMap.title
Definition

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

Control0..1
Typestring
Summarytrue
Comments

This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.

StructureMap.status
Definition

The status of this structure map. Enables tracking the life-cycle of the content.

Control1..1
Terminology BindingPublicationStatus (Required)
Typecode
Is Modifiertrue
Summarytrue
Comments

Allows filtering of structure maps that are appropriate for use vs. not.
This is labeled as "Is Modifier" because applications should not use a retired structure map without due consideration.

StructureMap.experimental
Definition

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

Control0..1
Typeboolean
Is Modifiertrue
Requirements

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

Summarytrue
Comments

Allows filtering of structure map that are appropriate for use vs. not. This is labeled as "Is Modifier" because applications should not use an experimental structure map in production.

StructureMap.date
Definition

The date (and optionally time) when the structure map was published. The date must change if and 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.

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 structure map. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

StructureMap.publisher
Definition

The name of the individual or organization that published the structure map.

Control0..1
Typestring
Requirements

Helps establish the "authority/credibility" of the structure map. May also allow for contact.

Summarytrue
Comments

Usually an organization, but may be an individual. The publisher (or steward) of the structure map is the organization or individual primarily responsible for the maintenance and upkeep of the structure 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 structure map. This item SHOULD be populated unless the information is available from context.

StructureMap.contact
Definition

Contact details to assist a user in finding and communicating with the publisher.

Control0..*
TypeContactDetail
Summarytrue
Comments

May be a web site, an email address, a telephone number, etc.

StructureMap.description
Definition

A free text natural language description of the structure map from a consumer's perspective.

Control0..1
Typemarkdown
Comments

This description can be used to capture details such as why the structure map was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the structure map as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the profile is presumed to be the predominant language in the place the profile was created).

StructureMap.useContext
Definition

The content was developed with a focus and intent of supporting the contexts that are listed. These terms may be used to assist with indexing and searching for appropriate structure map instances.

Control0..*
TypeUsageContext
Requirements

Assist in searching for appropriate content.

Summarytrue
Comments

When multiple useContexts are specified, there is no expectation whether all or any of the contexts apply.

StructureMap.jurisdiction
Definition

A legal or geographic region in which the structure map is intended to be used.

Control0..*
Terminology BindingJurisdiction ValueSet (Extensible)
TypeCodeableConcept
Summarytrue
Comments

It may be possible for the structure map to be used in jurisdictions other than those for which it was originally designed or intended.

StructureMap.purpose
Definition

Explaination of why this structure map is needed and why it has been designed as it has.

Control0..1
Typemarkdown
Comments

This element does not describe the usage of the structure map Instead it provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this structure map.

StructureMap.copyright
Definition

A copyright statement relating to the structure map and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the structure map.

Control0..1
Typemarkdown
Requirements

Consumers must be able to determine any legal restrictions on the use of the structure map and/or its content.

Alternate NamesLicense; Restrictions
StructureMap.structure
