Подробное описание элементов ресурса GraphDefinition.

GraphDefinition
Element IdGraphDefinition
Definition

A formal computable definition of a graph of resources - that is, a coherent set of resources that form a graph by following references. The Graph Definition resource defines a set and makes rules about the set.

GraphDefinition.url
Element IdGraphDefinition.url
Definition

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

Control0..1
Typeuri
Requirements

Allows the graph definition 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.

GraphDefinition.version
Element IdGraphDefinition.version
Definition

The identifier that is used to identify this version of the graph definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the graph definition 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 graph definition 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 graph definition with the format [url]|[version].

GraphDefinition.name
Element IdGraphDefinition.name
Definition

A natural language name identifying the graph definition. 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 alphanumeric type name to ensure that it is machine-processing friendly.

GraphDefinition.status
Element IdGraphDefinition.status
Definition

The status of this graph definition. Enables tracking the life-cycle of the content.

Control1..1
Terminology BindingPublicationStatus (Required)
Typecode
Is Modifiertrue (Reason: This is labeled as "Is Modifier" because applications should not use a retired {{title}} without due consideration)
Summarytrue
Comments

Allows filtering of graph definitions that are appropriate for use versus not.

GraphDefinition.experimental
Element IdGraphDefinition.experimental
Definition

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

Control0..1
Typeboolean
Requirements

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

Summarytrue
Comments

Allows filtering of graph definitions that are appropriate for use versus not.

GraphDefinition.date
Element IdGraphDefinition.date
Definition

The date (and optionally time) when the graph definition 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 graph definition 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 graph definition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

GraphDefinition.publisher
Element IdGraphDefinition.publisher
Definition

The name of the organization or individual that published the graph definition.

Control0..1
Typestring
Requirements

Helps establish the "authority/credibility" of the graph definition. May also allow for contact.

Summarytrue
Comments

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

GraphDefinition.contact
Element IdGraphDefinition.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.

GraphDefinition.description
Element IdGraphDefinition.description
Definition

A free text natural language description of the graph definition from a consumer's perspective.

Control0..1
Typemarkdown
Comments

This description can be used to capture details such as why the graph definition 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 graph definition 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 graph definition is presumed to be the predominant language in the place the graph definition was created).

GraphDefinition.useContext
Element IdGraphDefinition.useContext
Definition

The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate graph definition instances.

Control0..*
TypeUsageContext
Requirements

Assist in searching for appropriate content.

Summarytrue
Comments

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

GraphDefinition.jurisdiction
Element IdGraphDefinition.jurisdiction
Definition

A legal or geographic region in which the graph definition is intended to be used.

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

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

GraphDefinition.purpose
Element IdGraphDefinition.purpose
Definition

Explanation of why this graph definition is needed and why it has been designed as it has.

Control0..1
Typemarkdown
Comments

This element does not describe the usage of the graph definition. 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 graph definition.

GraphDefinition.start
Element IdGraphDefinition.start

GraphDefinition.link.path
Element IdGraphDefinition.link.path
Definition
