Source CodeRelationshipTarget CodeComment
MessageHeader.meta (meta)is equivalent toMessageHeader.metaElement `MessageHeader.meta` is mapped to FHIR R5 element `MessageHeader.meta` as `Equivalent`.
MessageHeader.implicitRules (implicitRules)is equivalent toMessageHeader.implicitRulesElement `MessageHeader.implicitRules` is mapped to FHIR R5 element `MessageHeader.implicitRules` as `Equivalent`. 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.
MessageHeader.language (language)is equivalent toMessageHeader.languageElement `MessageHeader.language` is mapped to FHIR R5 element `MessageHeader.language` as `Equivalent`. 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).
MessageHeader.text (text)is equivalent toMessageHeader.textElement `MessageHeader.text` is mapped to FHIR R5 element `MessageHeader.text` as `Equivalent`. 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.
MessageHeader.contained (contained)is equivalent toMessageHeader.containedElement `MessageHeader.contained` is mapped to FHIR R5 element `MessageHeader.contained` as `Equivalent`. 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.
MessageHeader.event[x] (event[x])is equivalent toMessageHeader.event[x]Element `MessageHeader.event[x]` is mapped to FHIR R5 element `MessageHeader.event[x]` as `Equivalent`. The target context `MessageHeader.event[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `MessageHeader`. The time of the event will be found in the focus resource. The time of the message will be found in [Bundle.timestamp](https://hl7.org/fhir/bundle-definition.html#Bundle.timestamp).
MessageHeader.destination (destination)is broader thanMessageHeader.destinationElement `MessageHeader.destination` is mapped to FHIR R5 element `MessageHeader.destination` as `Equivalent`. There SHOULD be at least one destination, but in some circumstances, the source system is unaware of any particular destination system.
MessageHeader.destination.name (name)is equivalent toMessageHeader.destination.nameElement `MessageHeader.destination.name` is mapped to FHIR R5 element `MessageHeader.destination.name` as `Equivalent`.
MessageHeader.destination.target (target)is equivalent toMessageHeader.destination.targetElement `MessageHeader.destination.target` is mapped to FHIR R5 element `MessageHeader.destination.target` as `Equivalent`.
MessageHeader.destination.endpoint (endpoint)is equivalent toMessageHeader.destination.endpoint[x]Element `MessageHeader.destination.endpoint` is mapped to FHIR R5 element `MessageHeader.destination.endpoint[x]` as `Equivalent`. The target context `MessageHeader.destination.endpoint[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `MessageHeader.destination`. The id may be a non-resolvable URI for systems that do not use standard network-based addresses.
MessageHeader.destination.receiver (receiver)is equivalent toMessageHeader.destination.receiverElement `MessageHeader.destination.receiver` is mapped to FHIR R5 element `MessageHeader.destination.receiver` as `Equivalent`.
MessageHeader.sender (sender)is equivalent toMessageHeader.senderElement `MessageHeader.sender` is mapped to FHIR R5 element `MessageHeader.sender` as `Equivalent`. Use case is for where a (trusted) sending system is responsible for multiple organizations, and therefore cannot differentiate based on source endpoint / authentication alone.
MessageHeader.author (author)is equivalent toMessageHeader.authorElement `MessageHeader.author` is mapped to FHIR R5 element `MessageHeader.author` as `Equivalent`. Usually only for the request but can be used in a response.
MessageHeader.source (source)is broader thanMessageHeader.sourceElement `MessageHeader.source` is mapped to FHIR R5 element `MessageHeader.source` as `Equivalent`.
MessageHeader.source.name (name)is equivalent toMessageHeader.source.nameElement `MessageHeader.source.name` is mapped to FHIR R5 element `MessageHeader.source.name` as `Equivalent`.
MessageHeader.source.software (software)is equivalent toMessageHeader.source.softwareElement `MessageHeader.source.software` is mapped to FHIR R5 element `MessageHeader.source.software` as `Equivalent`.
MessageHeader.source.version (version)is equivalent toMessageHeader.source.versionElement `MessageHeader.source.version` is mapped to FHIR R5 element `MessageHeader.source.version` as `Equivalent`.
MessageHeader.source.contact (contact)is equivalent toMessageHeader.source.contactElement `MessageHeader.source.contact` is mapped to FHIR R5 element `MessageHeader.source.contact` as `Equivalent`.
MessageHeader.source.endpoint (endpoint)is equivalent toMessageHeader.source.endpoint[x]Element `MessageHeader.source.endpoint` is mapped to FHIR R5 element `MessageHeader.source.endpoint[x]` as `Equivalent`. The target context `MessageHeader.source.endpoint[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `MessageHeader.source`. The id may be a non-resolvable URI for systems that do not use standard network-based addresses.
MessageHeader.responsible (responsible)is equivalent toMessageHeader.responsibleElement `MessageHeader.responsible` is mapped to FHIR R5 element `MessageHeader.responsible` as `Equivalent`. Usually only for the request but can be used in a response.
MessageHeader.reason (reason)is equivalent toMessageHeader.reasonElement `MessageHeader.reason` is mapped to FHIR R5 element `MessageHeader.reason` as `Equivalent`.
MessageHeader.response (response)is broader thanMessageHeader.responseElement `MessageHeader.response` is mapped to FHIR R5 element `MessageHeader.response` as `Equivalent`.
MessageHeader.response.identifier (identifier)is broader thanMessageHeader.response.identifierElement `MessageHeader.response.identifier` is mapped to FHIR R5 element `MessageHeader.response.identifier` as `SourceIsBroaderThanTarget`. The mappings for `MessageHeader.response.identifier` do not cover the following types: id. The mappings for `MessageHeader.response.identifier` do not cover the following types based on type expansion: value.
MessageHeader.response.code (code)is equivalent toMessageHeader.response.codeElement `MessageHeader.response.code` is mapped to FHIR R5 element `MessageHeader.response.code` as `Equivalent`. This is a generic response to the request message. Specific data for the response will be found in MessageHeader.focus.
MessageHeader.response.details (details)is equivalent toMessageHeader.response.detailsElement `MessageHeader.response.details` is mapped to FHIR R5 element `MessageHeader.response.details` as `Equivalent`. This SHALL be contained in the bundle. If any of the issues are errors, the response code SHALL be an error.
MessageHeader.focus (focus)is equivalent toMessageHeader.focusElement `MessageHeader.focus` is mapped to FHIR R5 element `MessageHeader.focus` as `Equivalent`. The data is defined where the transaction type is defined. The transaction data is always included in the bundle that is the full message. Only the root resource is specified. The resources it references should be contained in the bundle but are not also listed here. Multiple repetitions are allowed to cater for merges and other situations with multiple focal targets.
MessageHeader.definition (definition)is equivalent toMessageHeader.definitionElement `MessageHeader.definition` is mapped to FHIR R5 element `MessageHeader.definition` as `Equivalent`.

Group 2 Mapping from http://hl7.org/fhir/StructureDefinition/MessageHeader|4.3.0 to R4B: The source of the data entry (new)version: 0.1.0)

Source CodeRelationshipTarget CodeComment
MessageHeader.enterer (enterer)is broader thanExtension (R4B: The source of the data entry (new))Element `MessageHeader.enterer` has a context of MessageHeader based on following the parent source element upwards and mapping to `MessageHeader`. Element `MessageHeader.enterer` has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element). Usually only for the request but can be used in a response.

Group 3 Mapping from http://hl7.org/fhir/StructureDefinition/MessageHeader|4.3.0 to R4B: Id of original message additional typesversion: 0.1.0)

MessageHeader.response.identifier (identifier)is equivalent toExtension (R4B: Id of original message additional types)Element `MessageHeader.response.identifier` is mapped to FHIR R5 element `MessageHeader.response.identifier` as `SourceIsBroaderThanTarget`. The mappings for `MessageHeader.response.identifier` do not cover the following types: id. The mappings for `MessageHeader.response.identifier` do not cover the following types based on type expansion: value.
