5.3 Resource CapabilityStatement - Content

FHIR Infrastructure icon Work Group Maturity Level : N   Normative (from v4.0.0) Security Category : Anonymous Compartments : No defined compartments

A Capability Statement documents a set of capabilities (behaviors) of a FHIR Server or Client 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.

5.3.1 Scope and Usage

The capability statement is a key part of the overall conformance framework in FHIR. It is used as a statement of the features of actual software, or of a set of rules for an application to provide. This statement connects to all the detailed statements of functionality, such as StructureDefinitions and ValueSets . This composite statement of application capability may be used for system compatibility testing, code generation, or as the basis for a conformance assessment. For further information about Conformance testing, see Conformance Rules and Profiling FHIR .

Specifically, capability statements are used in one of three ways:

Instance implementation must be present and software may be present
Capability implementation must be absent, software must be present
Requirements implementation and software must be absent

5.3.1.1 Instance: Describe an actual implementation

In this scenario, the capability statement describes the capabilities of a deployed and configured solution available at a particular access point or set of access points. The statement describes exactly how to interface with that deployed solution and thus provides for a degree of self-configuration of software solutions.

This is the type of statement that FHIR restful solutions are expected to make available on invocation of the capabilities operation. It is also the type of statement that forms a basis for the testing, certification or commissioning of specific software installations.

5.3.1.2 Capability: Describe software solution capabilities

In this scenario, the capability statement describes generic capabilities of a software application or component solution. The solution might be available for purchase or other acquisition and might be deployed and configured at any number of independent sites. Because it is not dependent on any particular implementation, the profile cannot provide specific details such as endpoint addresses. It may also need to document various configurations in which the application can be set up or describe the degree of customizability associated with the solution.

This type of statement may be used as a marketing tool by software and system developers to formally describe their capabilities. It can also be used as the basis for conformance testing of software solutions independent of a particular installation.

5.3.1.3 Requirements: Describe a desired solution

In this scenario, the capability statement describes the capabilities of a desired system. It might be used as part of an architectural design process to document needed system capabilities, or might be used as part of an RFP process to formally document the requirements of a requested solution and to document the criteria by which proposals will be evaluated.

These three types of profiles can be used together. A requirements statement can be compared against the solution statements proffered by respondents to an RFP. A solution statement for a software package forms the starting point for the implementation statement associated with a particular installation of that software package.

CapabilityStatements of type "requirement" describe what capabilities are potentially relevant; additional documentation or extensions (see capabilitystatement-expectation ) within the CapabilityStatement are expected to make more explicit statements of degree of expectation associated with each capability.

5.3.2 Background and Context

Capability Statements provide for a degree of automatic configuration and adaptation. However, capturing absolutely every variation that could impact the interoperability of two systems, let alone keeping that detailed information up-to-date as systems evolve through maintenance and upgrades, is rarely practical. Therefore, capability statements should be seen as an interim step. They provide a degree of automation. However, they also provide a great deal of human-readable content that can minimize the need for direct communication between the operators of the systems being configured to interoperate.

5.3.2.1 Supporting Multiple Versions

Applications may implement multiple versions. If they do, then a CapabilityStatement describes the system's support for a particular version of FHIR, and the system will have multiple statements, one for each version it supports. For further information, see Managing Multiple Versions , and the $versions operation.

5.3.2.2 Mixed Normative Content

While the core of the CapabilityStatement resource is Normative , many of the flags that indicate exactly how the system operates are marked as trial-use . Roughly, the portions of the resource that correspond to OpenAPI document icon elements are normative.

Applications looking for normative stability should only use the normative parts of the resource, and not populate or ignore the portions labelled trial-use. To assist with this, clients can ask for the server to return a 'Normative content only' CapabilityStatement using the mode parameter on /metadata .

Community discussion regarding more capable, efficient and computable representations of an applications capabilities may lead to change to the trial-use parts of this resource or the creation of new resources and/or functionality in future versions of this specification.

This SHOULD be globally unique and SHOULD be a literal address 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 url : uri [0..1] A formal identifier that is used to identify this CapabilityStatement when it is represented in other formats, or referenced in a specification, model, design or an instance identifier : Identifier [0..*] 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.

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 instantiates : canonical [0..*] « CapabilityStatement » 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 imports : canonical [0..*] « CapabilityStatement » The version of the FHIR specification that this CapabilityStatement describes (which SHALL be the same as the FHIR version of the CapabilityStatement itself).

For example, if declared on Observation, this profile is the "superset" of capabilities for laboratory *and* vitals *and* other domains. See further discussion in [Using Profiles](profiling.html#profile-uses) profile : canonical [0..1] « StructureDefinition » A list of profiles representing different use cases the system hosts/produces. A supported profile is a statement about the functionality of the data and services provided by the server (or the client) for supported use cases. For example, a system can define and declare multiple Observation profiles for laboratory observations, vital sign observations, etc. By declaring supported profiles, systems provide a way to determine whether individual resources are conformant. See further discussion in [Using Profiles](profiling.html#profile-uses) supportedProfile : canonical [0..*] « StructureDefinition » Additional information about the resource type used by the system documentation : markdown [0..1] 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 versioning : code [0..1] « null (Strength=Required) ResourceVersionPolicy ! » A flag for whether the server is able to return past versions as part of the vRead operation readHistory : boolean [0..1] 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 updateCreate : boolean [0..1] A flag that indicates that the server supports conditional create conditionalCreate : boolean [0..1] A code that indicates how the server supports conditional read conditionalRead : code [0..1] « null (Strength=Required) ConditionalReadStatus ! » A flag that indicates that the server supports conditional update conditionalUpdate : boolean [0..1] A flag that indicates that the server supports conditional patch conditionalPatch : boolean [0..1] A code that indicates how the server supports conditional delete conditionalDelete : code [0..1] « null (Strength=Required) ConditionalDeleteStatus ! » A set of flags that defines how references are supported referencePolicy : code [0..*] « null (Strength=Required) ReferenceHandlingPolicy ! » A list of _include values supported by the server searchInclude : string [0..*] A list of _revinclude (reverse include) values supported by the server searchRevInclude : string [0..*] ResourceInteraction Coded identifier of the operation, supported by the system resource code : code [1..1] « null (Strength=Required) TypeRestfulInteraction ! » 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' documentation : markdown [0..1] SearchParam The label used for the search parameter in this particular system's API - i.e. the 'name' portion of the name-value pair that will appear as part of the search URL. This SHOULD be the same as the SearchParameter.code of the defining SearchParameter. However, it can sometimes differ if necessary to disambiguate when a server supports multiple SearchParameters that happen to share the same code name : string [1..1] « This element has or is affected by some invariants C » 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 definition : canonical [0..1] « SearchParameter » The type of value a search parameter refers to, and how the content is interpreted type : code [1..1] « null (Strength=Required) SearchParamType ! » This allows documentation of any distinct behaviors about how the search parameter is used. For example, text matching algorithms documentation : markdown [0..1] Operation The name of the operation or query. For an operation, this name is prefixed with $ and used in the URL. For a query, this is the name used in the _query parameter when the query is called. This SHOULD be the same as the OperationDefinition.code of the defining OperationDefinition. However, it can sometimes differ if necessary to disambiguate when a server supports multiple OperationDefinition that happen to share the same code name : string [1..1] 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 definition : canonical [1..1] « OperationDefinition » Documentation that describes anything special about the operation behavior, possibly detailing different behavior for system, type and instance-level invocation of the operation documentation : markdown [0..1] SystemInteraction A coded identifier of the operation, supported by the system code : code [1..1] « null (Strength=Required) SystemRestfulInteraction ! » Guidance specific to the implementation of this operation, such as limitations on the kind of transactions allowed, or information about system wide search is implemented documentation : markdown [0..1] Messaging Length if the receiver's reliable messaging cache in minutes (if a receiver) or how long the cache length on the receiver should be (if a sender) reliableCache : unsignedInt [0..1] Documentation about the system's messaging capabilities for this endpoint not otherwise documented by the capability statement. For example, the process for becoming an authorized messaging exchange partner documentation : markdown [0..1] Endpoint A list of the messaging transport protocol(s) identifiers, supported by this endpoint protocol : Coding [1..1] « null (Strength=Extensible) MessageTransport + » The network address of the endpoint. For solutions that do not use network addresses for routing, it can be just an identifier address : url [1..1] SupportedMessage The mode of this event declaration - whether application is sender or receiver mode : code [1..1] « null (Strength=Required) EventCapabilityMode ! » Points to a message definition that identifies the messaging event, message structure, allowed responses, etc definition : canonical [1..1] « MessageDefinition » Document Mode of this document declaration - whether an application is a producer or consumer mode : code [1..1] « null (Strength=Required) DocumentMode ! » « This element has or is affected by some invariants C » A description of how the application supports or uses the specified document profile. For example, when documents are created, what action is taken with consumed documents, etc documentation : markdown [0..1] A profile on the document Bundle that constrains which resources are present, and their contents profile : canonical [1..1] « StructureDefinition » « This element has or is affected by some invariants C » Software that is covered by this capability statement.

CapabilityStatement ( DomainResource ) + CanonicalResource 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 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 url : uri [0..1] A formal identifier that is used to identify this CapabilityStatement when it is represented in other formats, or referenced in a specification, model, design or an instance identifier : Identifier [0..*] 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 version : string [0..1] Indicates the mechanism used to compare versions to determine which is more current versionAlgorithm[x] : DataType [0..1] « string | Coding ; null (Strength=Extensible) VersionAlgorithm + » 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 name : string [0..1] « This element has or is affected by some invariants C » A short, descriptive, user-friendly title for the capability statement title : string [0..1] The status of this capability statement. Enables tracking the life-cycle of the content (this element modifies the meaning of other elements) status : code [1..1] « null (Strength=Required) PublicationStatus ! » 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 experimental : boolean [0..1] The date (and optionally time) when the capability statement 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 capability statement changes date : dateTime [1..1] The name of the organization or individual responsible for the release and ongoing maintenance of the capability statement publisher : string [0..1] Contact details to assist a user in finding and communicating with the publisher contact : ContactDetail [0..*] 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 description : markdown [0..1] « This element has or is affected by some invariants C » 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 useContext : UsageContext [0..*] A legal or geographic region in which the capability statement is intended to be used jurisdiction : CodeableConcept [0..*] « null (Strength=Extensible) JurisdictionValueSet + » Explanation of why this capability statement is needed and why it has been designed as it has purpose : markdown [0..1] 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 copyright : markdown [0..1] A short string (<50 characters), suitable for inclusion in a page footer that identifies the copyright holder, effective period, and optionally whether rights are resctricted. (e.g. 'All rights reserved', 'Some rights reserved') copyrightLabel : string [0..1] 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) kind : code [1..1] « null (Strength=Required) CapabilityStatementKind ! » « This element has or is affected by some invariants C » 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 instantiates : canonical [0..*] « CapabilityStatement » 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 imports : canonical [0..*] « CapabilityStatement » The version of the FHIR specification that this CapabilityStatement describes (which SHALL be the same as the FHIR version of the CapabilityStatement itself). There is no default value fhirVersion : code [1..1] « null (Strength=Required) FHIRVersion ! » A list of the formats supported by this implementation using their content types format : code [1..*] « null (Strength=Required) MimeTypes ! » A list of the patch formats supported by this implementation using their content types patchFormat : code [0..*] « The mime type of an attachment. Any valid mime type is allowed.

This forms the base for REST interfaces as well as the mailbox and document interfaces url : url [0..1] The organization responsible for the management of the instance and oversight of the data on the server at the specified URL custodian : Reference [0..1] « Organization » Rest Identifies whether this portion of the statement is describing the ability to initiate or receive restful operations mode : code [1..1] « null (Strength=Required) RestfulCapabilityMode ! » « This element has or is affected by some invariants C » Information about the system's restful capabilities that apply across all applications, such as security documentation : markdown [0..1] An absolute URI which is a reference to the definition of a compartment that the system supports. The reference is to a CompartmentDefinition resource by its canonical URL compartment : canonical [0..*] « CompartmentDefinition » Security Server adds CORS headers when responding to requests - this enables Javascript applications to use the server cors : boolean [0..1] Types of security services that are supported/required by the system service : CodeableConcept [0..*] « null (Strength=Extensible) RestfulSecurityService + » General description of how security works description : markdown [0..1] Resource A type of resource exposed via the restful interface type : code [1..1] « null (Strength=Required) ResourceType ! » « This element has or is affected by some invariants C » A system-wide profile that is applied across *all* instances of the resource supported by the system. For example, if declared on Observation, this profile is the "superset" of capabilities for laboratory *and* vitals *and* other domains. See further discussion in [Using Profiles](profiling.html#profile-uses) profile : canonical [0..1] « StructureDefinition » A list of profiles representing different use cases the system hosts/produces. A supported profile is a statement about the functionality of the data and services provided by the server (or the client) for supported use cases. For example, a system can define and declare multiple Observation profiles for laboratory observations, vital sign observations, etc. By declaring supported profiles, systems provide a way to determine whether individual resources are conformant. See further discussion in [Using Profiles](profiling.html#profile-uses) supportedProfile : canonical [0..*] « StructureDefinition » Additional information about the resource type used by the system documentation : markdown [0..1] 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 versioning : code [0..1] « null (Strength=Required) ResourceVersionPolicy ! » A flag for whether the server is able to return past versions as part of the vRead operation readHistory : boolean [0..1] 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 updateCreate : boolean [0..1] A flag that indicates that the server supports conditional create conditionalCreate : boolean [0..1] A code that indicates how the server supports conditional read conditionalRead : code [0..1] « null (Strength=Required) ConditionalReadStatus ! » A flag that indicates that the server supports conditional update conditionalUpdate : boolean [0..1] A flag that indicates that the server supports conditional patch conditionalPatch : boolean [0..1] A code that indicates how the server supports conditional delete conditionalDelete : code [0..1] « null (Strength=Required) ConditionalDeleteStatus ! » A set of flags that defines how references are supported referencePolicy : code [0..*] « null (Strength=Required) ReferenceHandlingPolicy ! » A list of _include values supported by the server searchInclude : string [0..*] A list of _revinclude (reverse include) values supported by the server searchRevInclude : string [0..*] ResourceInteraction Coded identifier of the operation, supported by the system resource code : code [1..1] « null (Strength=Required) TypeRestfulInteraction ! » 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' documentation : markdown [0..1] SearchParam The label used for the search parameter in this particular system's API - i.e. the 'name' portion of the name-value pair that will appear as part of the search URL. This SHOULD be the same as the SearchParameter.code of the defining SearchParameter. However, it can sometimes differ if necessary to disambiguate when a server supports multiple SearchParameters that happen to share the same code name : string [1..1] « This element has or is affected by some invariants C » 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 definition : canonical [0..1] « SearchParameter » The type of value a search parameter refers to, and how the content is interpreted type : code [1..1] « null (Strength=Required) SearchParamType ! » This allows documentation of any distinct behaviors about how the search parameter is used. For example, text matching algorithms documentation : markdown [0..1] Operation The name of the operation or query. For an operation, this name is prefixed with $ and used in the URL. For a query, this is the name used in the _query parameter when the query is called. This SHOULD be the same as the OperationDefinition.code of the defining OperationDefinition. However, it can sometimes differ if necessary to disambiguate when a server supports multiple OperationDefinition that happen to share the same code name : string [1..1] 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 definition : canonical [1..1] « OperationDefinition » Documentation that describes anything special about the operation behavior, possibly detailing different behavior for system, type and instance-level invocation of the operation documentation : markdown [0..1] SystemInteraction A coded identifier of the operation, supported by the system code : code [1..1] « null (Strength=Required) SystemRestfulInteraction ! » Guidance specific to the implementation of this operation, such as limitations on the kind of transactions allowed, or information about system wide search is implemented documentation : markdown [0..1] Messaging Length if the receiver's reliable messaging cache in minutes (if a receiver) or how long the cache length on the receiver should be (if a sender) reliableCache : unsignedInt [0..1] Documentation about the system's messaging capabilities for this endpoint not otherwise documented by the capability statement. For example, the process for becoming an authorized messaging exchange partner documentation : markdown [0..1] Endpoint A list of the messaging transport protocol(s) identifiers, supported by this endpoint protocol : Coding [1..1] « null (Strength=Extensible) MessageTransport + » The network address of the endpoint. For solutions that do not use network addresses for routing, it can be just an identifier address : url [1..1] SupportedMessage The mode of this event declaration - whether application is sender or receiver mode : code [1..1] « null (Strength=Required) EventCapabilityMode ! » Points to a message definition that identifies the messaging event, message structure, allowed responses, etc definition : canonical [1..1] « MessageDefinition » Document Mode of this document declaration - whether an application is a producer or consumer mode : code [1..1] « null (Strength=Required) DocumentMode ! » « This element has or is affected by some invariants C » A description of how the application supports or uses the specified document profile. For example, when documents are created, what action is taken with consumed documents, etc documentation : markdown [0..1] A profile on the document Bundle that constrains which resources are present, and their contents profile : canonical [1..1] « StructureDefinition » « This element has or is affected by some invariants C » 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 software [0..1] Identifies a specific implementation instance that is described by the capability statement - i.e. a particular installation, rather than the capabilities of a software program implementation [0..1] Information about security implementation from an interface perspective - what a client needs to know security [0..1] Identifies a restful operation supported by the solution interaction [0..*] 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 searchParam [0..*] Definition of an operation or a named query together with its parameters and their meaning and type.

5.3.5 Notes:

  • The CapabilityStatement resource provides for an application to describe its use of the RESTful paradigm paradigm, messaging events, or FHIR documents. Usually, Usually an application would only describe one, but more than one may be described described.
  • RESTful CapabilityStatement rules:
    • RESTful servers are required to provide this resource on demand . Servers SHALL specify what resource types and operations are supported, and SHOULD also specify profiles for each resource type.
    • The CapabilityStatement returned in the capabilities interaction may represent the specific capabilities granted to a specific user if retrieved with that specific user's credentials, if one is in context. Servers that require authentication SHOULD still return a CapabilityStatement before authentication/authorization is performed
    • RESTful clients SHOULD publish a capability statement
    • The search parameters that a server supports (or a client makes use of) are specified in the resource profile that the capability statement references
    • Resource Types or operations that are not listed are not supported
  • Messaging CapabilityStatement rules:
    • The interpretation of request and response depends on the mode. If the mode is sender, then request specifies what the application sends, and response specifies what it accepts. If the mode is "receiver", then this is reversed
    • If a request or response is not specified for an event, then no rules are made for it
    • Events that are not listed are not supported
    • The MessageDefinition resource is newly proposed and is still considered 'draft'. The supportedMessage element can be used in place of the event and the work group believes it may meet implementer needs better, however because the new mechanism has not yet been reviewed by ballot, the older 'event' mechanism has been retained. Implementers may use one or the other to define their capabilities. Feedback is welcome.
  • Document CapabilityStatement rules:
    • Document profiles should directly constrain the Document.information.class & type elements so that there is no ambiguity concerning which profile any given document conforms to.
  • Other service-based use of resources: Due to the variability of these services, the CapabilityStatement resource does not attempt to describe service-based use of resources. The various service specifications will need to describe this usage in their own way.

5.3.5.1 Timezone Discovery

If a server has a default timezone, it should be indicated via the timezone code extension on CapabilityStatement.meta .

5.3.5.2 Supporting Search

One of the most important parts of the CapabilityStatement is indicating what search functionality a server supports or a client uses. The search can specify the following things:

  • What resource types search is supported on, or used on
  • What search parameters are supported, and what their names are on this server (the server can use alternative names ). Note that clients can also choose to use alternative names for search parameters, but there is no expectation that servers will adapt for the client in this regard
  • Servers can define their own search parameters that are not sourced from elsewhere, and often to define searches on extensions (see example )
  • What include and reverse includes a server supports, or a client uses
  • The Capability Statement does not support saying anything about modifiers or chaining directly, but these kind of statements can be made in the referenced search parameter resources (using SearchParameter.derivedFrom to establish traceability to the original definition of the search parameter)
  • Systems can also make statements about their use or support for system wide search (not associated with a particular resource type)

Note to Implementers: It is useful to support discovery of which reverse chaining values a server supports. Clients should not assume that servers support reverse chaining everywhere they support forward chaining. This will require a new field somewhere (e.g., in CapabilityStatement or in SearchParameter). Will review with FHIR-I, re: the best place to put this.

The most important use of support for reverse (or forward!) chaining might be in establishing conformance requirements for a server, rather than in supporting "live" discovery of a server's capabilities. (The latter could simply be tested by a client, rather than relying on possibly-incomplete or possibly-incorrect discovery data.)

Open question #1 would we want a way for servers to advertise which specific pairs of (searched resource + reverse chained search params) it support. For example, a server might need to say that the following is supported: 

GET [base]/Patient?_has:Observation:subject:code=1234-5

... even though the following is not: 

GET [base]/Group?_has:Observation:subject:code=1234-5

Open question #2: concern is that the possibility space is so broad that it might not be worth capturing all of this in such detail. Where to draw the line?

Note to Implementers: There is no way for a server to communicate how it supports search at this time. FHIR-I plans to address this and other search issues for R6.

5.3.5.2 5.3.5.3 Supporting Profiles

A CapabilityStatement declares two different kinds of profiles for the functionality it describes. For a discussion of the use of these two types of resources, see two uses for profiles .

5.3.6 Search Parameters

Search parameters for this resource. See also the full list of search parameters for this resource , and check the Extensions registry for search parameters on extensions related to this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.
