0. Endpoint
Definition | The technical details of an endpoint that can be used for electronic services, such as for web services providing XDS.b or a REST endpoint for another FHIR server. This may include any security context information.
Short | The technical details of an endpoint that can be used for electronic services
Control | 0..*
Invariants | dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (`contained.contained.empty()`) dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (`contained.text.empty()`) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (`contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()`) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource (`contained.where(('#'+id in %resource.descendants().reference).not()).empty()`) dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (contained.text.empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource (contained.where(('#'+id in %resource.descendants().reference).not()).empty())
2. Endpoint.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content.
Short | A set of rules under which this content was created
Comments | 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. This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation.
Control | 0..1
Type | uri
Is Modifier | true because No Modifier Reason provideed in previous versions of FHIR
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
4. Endpoint.modifierExtension
Definition | 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. Usually modifier elements provide negation or qualification. In order 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.
Short | Extensions that cannot be ignored
Comments | 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.
Control | 0..*
Type | Extension
Is Modifier | true because No Modifier Reason provideed in previous versions of FHIR
Alternate Names | extensions, user content
6. Endpoint.status
Definition | active | suspended | error | off | test.
Short | active | suspended | error | off | entered-in-error | test
Comments | This element is labeled as a modifier because the status contains codes that mark the endpoint as not currently valid.
Control | 1..1
Binding | The codes SHALL be taken from EndpointStatus http://hl7.org/fhir/ValueSet/endpoint-status|3.0.2 (required to `http://hl7.org/fhir/ValueSet/endpoint-status|3.0.2` ) The status of the endpoint
Type | code
Is Modifier | true because No Modifier Reason provideed in previous versions of FHIR
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
8. Endpoint.connectionType
Definition | A coded value that represents the technical details of the usage of this endpoint, such as what WSDLs should be used in what way. (e.g. XDS.b/DICOM/cds-hook).
Short | Protocol/Profile/Standard to be used with this endpoint connection
Comments | For additional connectivity details for the protocol, extensions will be used at this point, as in the XDS example.
Control | 1..1
Binding | Unless not suitable, these codes SHALL be taken from Endpoint Connection Type http://hl7.org/fhir/ValueSet/endpoint-connection-type|3.0.2 (extensible to `http://hl7.org/fhir/ValueSet/endpoint-connection-type|3.0.2` )
Type | Coding
Summary | true
10. Endpoint.managingOrganization
Definition | The organization that manages this endpoint (even if technically another organisation is hosting this in the cloud, it is the organisation associated with the data).
Short | Organization that manages this endpoint (may not be the organization that exposes the endpoint)
Comments | This property is not typically used when searching for Endpoint resources for usage. The typical usage is via the reference from an aplicable Organization/Location/Practitioner resource, which is where the context is provided. Multiple Locations may reference a single endpoint, and don't have to be within the same organization resource, but most likely within the same organizational hierarchy.
Control | 0..1
Type | Reference(Organization)
Must Support | true
Summary | true
12. Endpoint.payloadType
Definition | The payload type describes the acceptable content that can be communicated on the endpoint.
Short | The type of content that may be used at this endpoint (e.g. XDS Discharge summaries)
Comments | The payloadFormat describes the serialization format of the data, where the payloadType indicates the specific document/schema that is being transferred; e.g. DischargeSummary or CarePlan.
Control | 1..*
Binding | For example codes, see Endpoint Payload Type http://hl7.org/fhir/ValueSet/endpoint-payload-type|3.0.2 (example to `http://hl7.org/fhir/ValueSet/endpoint-payload-type|3.0.2` )
Type | CodeableConcept
Summary | true
14. Endpoint.address
Definition | The uri that describes the actual end-point to connect to.
Short | The technical base address for connecting to this endpoint
Comments | For rest-hook, and websocket, the end-point must be an http: or https: URL; for email, a mailto: url, for sms, a tel: url, and for message the endpoint can be in any form of url the server understands (usually, http: or mllp:). The URI is allowed to be relative; in which case, it is relative to the server end-point (since their may be more than one, clients should avoid using relative URIs) This address will be to the service base, without any parameters, or sub-services or resources tacked on. E.g. for a WADO-RS endpoint, the url should be "https://pacs.hospital.org/wado-rs" and not "https://pacs.hospital.org/wado-rs/studies/1.2.250.1.59.40211.12345678.678910/series/1.2.250.1.59.40211.789001276.14556172.67789/instances/...".

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

8. Endpoint.language
Definition | The base language in which the resource is written.
Short | Language of the resource content
Comments | 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).
Control | 0..1
Binding | Unless not suitable, these codes SHALL be taken from Common Languages (extensible to `http://hl7.org/fhir/ValueSet/languages|3.0.2` ) A human language.

Primitive Value | This primitive element may be present, or absent, or replaced by an extension
10. Endpoint.text
Definition | A human-readable narrative that contains a summary of the resource, and may 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.
Short | Text summary of the resource, for human interpretation
Comments | 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 in formation is added later.
Control | 0..1 This element is affected by the following invariants: dom-1
Type | Narrative
Alternate Names | narrative, html, xhtml, display
12. Endpoint.contained
Definition | 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.
Short | Contained, inline Resources
Comments | 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.
Control | 0..*
Type | Resource
Alternate Names | inline resources, anonymous resources, contained resources
14. Endpoint.extension
Definition | May be used to represent additional information that is not part of the basic definition of the resource. In order 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.
Short | Additional Content defined by implementations
Comments | 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.
