CapabilityStatement

A Capability Statement documents a set of capabilities (behaviors) of a FHIR Server for a particular version of FHIR that may be used as a statement of actual server functionality or a statement of required or desired server implementation.

Elements

NameRequiredTypeDescription
urluri

Canonical identifier for this capability statement, represented as a URI (globally unique)

Details

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

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](resource.html#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](resource.html#meta) element to indicate where the current master source of the resource can be found.

versionstring

Business version of the capability statement

Details

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

There may be different capability statement 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 capability statement with the format [url]|[version].

namestring

Name for this capability statement (computer friendly)

Details

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

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.

titlestring

Name for this capability statement (human friendly)

Details

A short, descriptive, user-friendly title for the capability statement.

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

statuscode

draft | active | retired | unknown

Details

The status of this capability statement. Enables tracking the life-cycle of the content.

Allows filtering of capability statements that are appropriate for use versus not.This is not intended for use with actual capability statements, but where capability statements are used to describe possible or desired systems.

experimentalboolean

For testing purposes, not real usage

Details

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

Allows filtering of capability statements that are appropriate for use versus not.

datedateTime

Date last changed

Details

The date (and optionally time) when the capability statement 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 capability statement changes.

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

publisherstring

Name of the publisher (organization or individual)

Details

The name of the organization or individual that published the capability statement.

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

contactContactDetail[]

Contact details for the publisher

Details

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

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

descriptionmarkdown

Natural language description of the capability statement

Details

A free text natural language description of the capability statement from a consumer's perspective. Typically, this is used when the capability statement describes a desired rather than an actual solution, for example as a formal expression of requirements as part of an RFP.

This description can be used to capture details such as why the capability statement 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 capability statement 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 capability statement is presumed to be the predominant language in the place the capability statement was created).This does not need to be populated if the description is adequately implied by the software or implementation details.

useContextUsageContext[]

The context that the content is intended to support

Details

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 capability statement instances.

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

jurisdictionCodeableConcept[]

Intended jurisdiction for capability statement (if applicable)

Details

A legal or geographic region in which the capability statement is intended to be used.

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

purposemarkdown

Why this capability statement is defined

Details

Explanation of why this capability statement is needed and why it has been designed as it has.

This element does not describe the usage of the capability statement. 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 capability statement.

copyrightmarkdown

Use and/or publishing restrictions

Details

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

kindcode

instance | capability | requirements

Details

The way that this statement is intended to be used, to describe an actual running instance of software, a particular product (kind, not instance of software) or a class of implementation (e.g. a desired purchase).

instantiatescanonical[]

Canonical URL of another capability statement this implements

Details

Reference to a canonical URL of another CapabilityStatement that this software implements. This capability statement is a published API description that corresponds to a business service. The server may actually implement a subset of the capability statement it claims to implement, so the capability statement must specify the full capability details.

HL7 defines the following Services: [Terminology Service](terminology-service.html). Many [Implementation Guides](http://fhir.org/guides/registry) define additional services.

importscanonical[]

Canonical URL of another capability statement this adds to

Details

Reference to a canonical URL of another CapabilityStatement that this software adds to. The capability statement automatically includes everything in the other statement, and it is not duplicated, though the server may repeat the same resources, interactions and operations to add additional details to them.

the contents of any directly or indirectly imported CapabilityStatements SHALL NOT overlap, i.e. they cannot refer to the same rest/resource, operations/name, searchparam/name, interaction/code, messaging/endpoint, document/mode pair. A capability statement that imports another CapabilityStatement automatically instantiates it too (though this is often not a very useful statement for the kinds of CapabilityStatements that are suitable for importing).

softwareCapabilityStatementSoftware

Software that is covered by this capability statement

Details

Software that is covered by this capability statement. It is used when the capability statement describes the capabilities of a particular software version, independent of an installation.

idstring

Unique id for inter-element referencing

Details

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

extensionExtension[]

Additional content defined by implementations

Details

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

modifierExtensionExtension[]

Extensions that cannot be ignored even if unrecognized

Details

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

namestring

Servers may implement multiple versions (see [Managing Multiple Versions](versioning.html), and the [$versions](capabilitystatement-operation-versions.html) operation). If they do, and the CapabilityStatement is requested from the server, then this fhirVersion will be either the version requested, or the server's default version.

formatcode[]

formats supported (xml | json | ttl | mime type)

Details

A list of the formats supported by this implementation using their content types.

"xml", "json" and "ttl" are allowed, which describe the simple encodings described in the specification (and imply appropriate bundle support). Otherwise, mime types are legal here.

patchFormatcode[]

Patch formats supported

Details

A list of the patch formats supported by this implementation using their content types.

At present, the patch mime types application/json-patch+json and application/xml-patch+xml are legal. Generally, if a server supports PATCH, it would be expected to support the patch formats and match the formats it supports, but this is not always possible or necessary.

typecode

A resource type that is supported

Details

A type of resource exposed via the restful interface.

profilecanonical

Base System profile for all uses of resource

Details

A specification of the profile that describes the solution's overall support for the resource, including any constraints on cardinality, bindings, lengths or other limitations. See further discussion in [Using Profiles](profiling.html#profile-uses).

The profile applies to all resources of this type - i.e. it is the superset of what is supported by the system.

supportedProfilecanonical[]

Profiles for use cases supported

Details

A list of profiles that represent different use cases supported by the system. For a server, "supported by the system" means the system hosts/produces a set of resources that are conformant to a particular profile, and allows clients that use its services to search using this profile and to find appropriate data. For a client, it means the system will search by this profile and process data according to the guidance implicit in the profile. See further discussion in [Using Profiles](profiling.html#profile-uses).

Supported profiles are different than the profile that applies to a particular resource in .rest.resource.profile. The resource profile is a general statement of what features of the resource are supported overall by the system - the sum total of the facilities it supports. A supported profile is a deeper statement about the functionality of the data and services provided by the server (or used by the client). A typical case is a laboratory system that produces a set of different reports - this is the list of types of data that it publishes. A key aspect of declaring profiles here is the question of how the client converts knowledge that the server publishes this data into working with the data; the client can inspect individual resources to determine whether they conform to a particular profile, but how does it find the ones that do? It does so by searching using the _profile parameter, so any resources listed here must be valid values for the _profile resource (using the identifier in the target profile).

documentationmarkdown

Additional information about the use of the resource type

Details

Additional information about the resource type used by the system.

interactionCapabilityStatementRestResourceInteraction[]

What operations are supported?

Details

Identifies a restful operation supported by the solution.

In general, a Resource will only appear in a CapabilityStatement if the server actually has some capabilities - e.g. there is at least one interaction supported. However interactions can be omitted to support summarization (_summary = true).

idstring

Unique id for inter-element referencing

Details

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

extensionExtension[]

Additional content defined by implementations

Details

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

codecode

read | vread | update | patch | delete | history-instance | history-type | create | search-type

Details

Coded identifier of the operation, supported by the system resource.

documentationmarkdown

Anything special about operation behavior

Details

Guidance specific to the implementation of this operation, such as 'delete is a logical delete' or 'updates are only allowed with version id' or 'creates permitted from pre-authorized certificates only'.

versioningcode

no-version | versioned | versioned-update

Details

This field is set to no-version to specify that the system does not support (server) or use (client) versioning for this resource type. If this has some other value, the server must at least correctly track and populate the versionId meta-property on resources. If the value is 'versioned-update', then the server supports all the versioning features, including using e-tags for version integrity in the API.

If a server supports versionIds correctly, it SHOULD support vread too, but is not required to do so.

readHistoryboolean

Whether vRead can return past versions

Details

A flag for whether the server is able to return past versions as part of the vRead operation.

It is useful to support the vRead operation for current operations, even if past versions aren't available.

updateCreateboolean

If update can commit to a new identity

Details

A flag to indicate that the server allows or needs to allow the client to create new identities on the server (that is, the client PUTs to a location where there is no existing resource). Allowing this operation means that the server allows the client to create new identities on the server.

Allowing the clients to create new identities on the server means that the system administrator needs to have confidence that the clients do not create clashing identities between them. Obviously, if there is only one client, this won't happen. While creating identities on the client means that the clients need to be managed, it's much more convenient for many scenarios if such management can be put in place.

conditionalCreateboolean

If allows/uses conditional create

Details

A flag that indicates that the server supports conditional create.

Conditional Create is mainly appropriate for interface engine scripts converting from other formats, such as v2.

conditionalReadcode

not-supported | modified-since | not-match | full-support

Details

A code that indicates how the server supports conditional read.

Conditional Read is mainly appropriate for interface engine scripts converting from other formats, such as v2.

conditionalUpdateboolean

If allows/uses conditional update

Details

A flag that indicates that the server supports conditional update.

Conditional Update is mainly appropriate for interface engine scripts converting from other formats, such as v2.

conditionalDeletecode

not-supported | single | multiple - how conditional delete is supported

Details

A code that indicates how the server supports conditional delete.

Conditional Delete is mainly appropriate for interface engine scripts converting from other formats, such as v2.

referencePolicycode[]

literal | logical | resolves | enforced | local

Details

A set of flags that defines how references are supported.

searchIncludestring[]

_revinclude values supported by the server

Details

A list of _revinclude (reverse include) values supported by the server.

If this list is empty, the server does not support reverse includes.

searchParamCapabilityStatementRestResourceSearchParam[]

Search parameters supported by implementation

Details

Search parameters for implementations to support and/or make use of - either references to ones defined in the specification, or additional ones defined for/by the implementation.

The search parameters should include the control search parameters such as _sort, _count, etc. that also apply to this resource (though many will be listed at [CapabilityStatement.rest.searchParam](capabilitystatement-definitions.html#CapabilityStatement.rest.searchParam)). The behavior of some search parameters may be further described by other code or extension elements, or narrative within the capability statement or linked [SearchParameter](searchparameter.html#) definitions.

idstring

Unique id for inter-element referencing

Details

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

extensionExtension[]

namestring

Name of search parameter

Details

The name of the search parameter used in the interface.

Parameter names cannot overlap with standard parameter names, and standard parameters cannot be redefined.

definitioncanonical

Source of definition for parameter

Details

An absolute URI that is a formal reference to where this parameter was first defined, so that a client can be confident of the meaning of the search parameter (a reference to [SearchParameter.url](searchparameter-definitions.html#SearchParameter.url)). This element SHALL be populated if the search parameter refers to a SearchParameter defined by the FHIR core specification or externally defined IGs.

This SHOULD be present, and matches refers to a SearchParameter by its canonical URL. If systems wish to document their support for modifiers, comparators, target resource types, and chained parameters, they should do using a search parameter resource. This element SHALL be populated if the search parameter refers to a SearchParameter defined by the FHIR core specification or externally defined IGs.

typecode

number | date | string | token | reference | composite | quantity | uri | special

Details

The type of value a search parameter refers to, and how the content is interpreted.

While this can be looked up from the definition, it is included here as a convenience for systems that autogenerate a query interface based on the server capability statement. It SHALL be the same as the type in the search parameter definition.

documentationmarkdown

Server-specific usage

Details

This allows documentation of any distinct behaviors about how the search parameter is used. For example, text matching algorithms.

operationCapabilityStatementRestResourceOperation[]

Definition of a resource operation

Details

Definition of an operation or a named query together with its parameters and their meaning and type. Consult the definition of the operation for details about how to invoke the operation, and the parameters.

Operations linked from CapabilityStatement.rest.resource.operation must have OperationDefinition.type = true or OperationDefinition.instance = true. If an operation that is listed in multiple CapabilityStatement.rest.resource.operation (e.g. for different resource types), then clients should understand that the operation is only supported on the specified resource types, and that may be a subset of those listed in OperationDefinition.resource.

Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

namestring

Name by which the operation/query is invoked

Details

The name of the operation or query. For an operation, this is the name prefixed with $ and used in the URL. For a query, this is the name used in the _query parameter when the query is called.

The name here SHOULD be the same as the name in the definition, unless there is a name clash and the name cannot be used. The name does not include the "$" portion that is always included in the URL.

definitioncanonical

The defined operation/query

Details

Where the formal definition can be found. If a server references the base definition of an Operation (i.e. from the specification itself such as ```http://hl7.org/fhir/OperationDefinition/ValueSet-expand```), that means it supports the full capabilities of the operation - e.g. both GET and POST invocation. If it only supports a subset, it must define its own custom [OperationDefinition](operationdefinition.html#) with a 'base' of the original OperationDefinition. The custom definition would describe the specific subset of functionality supported.

This can be used to build an HTML form to invoke the operation, for instance.

Inherited Elements

NameRequiredTypeDescription
idstring

Logical id of this artifact

Details

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

metaMeta

Metadata about the resource

Details

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

implicitRulesuri

A set of rules under which this content was created

Details

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

languagecode

Language of the resource content

Details

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

textNarrative

Text summary of the resource, for human interpretation

Details

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

containedResource[]

Contained, inline Resources

Details

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

extensionExtension[]

Additional content defined by implementations

Details

May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

modifierExtensionExtension[]

Extensions that cannot be ignored

Details

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
