Overview
This is the tree for the MessageHeader resource in the RDC project. You can find the resource on https://simplifier.net/rdcemrintegrations/message-header. Notice that the path in the URL is exactly the same as the placeholder.
| message-header (MessageHeader) | I | MessageHeader | There are no (further) constraints on this element Element idMessageHeader A resource that describes a message that is exchanged between systems DefinitionThe header for a message exchange that is either requesting or responding to an action. The reference(s) that are the subject of the action as well as other information related to the action are typically transmitted in a bundle in which the MessageHeader resource instance is the first resource in the bundle.
| |
| id | Σ | 0..1 | id | There are no (further) constraints on this element Element idMessageHeader.id Logical id of this artifact DefinitionThe 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. |
| meta | Σ | 0..1 | Meta | There are no (further) constraints on this element Element idMessageHeader.meta Metadata about the resource DefinitionThe metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource. |
| implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idMessageHeader.implicitRules A set of rules under which this content was created DefinitionA reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. 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. |
| language | 0..1 | codeBinding | There are no (further) constraints on this element Element idMessageHeader.language Language of the resource content DefinitionThe 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). A human language. Common Languages (extensible) | |
| text | I | 0..1 | Narrative | There are no (further) constraints on this element Element idMessageHeader.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display DefinitionA 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. 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.
|
| contained | 0..* | Resource | There are no (further) constraints on this element Element idMessageHeader.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources DefinitionThese 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.
| |
| extension | 0..* | Extension | There are no (further) constraints on this element Element idMessageHeader.extension Additional Content defined by implementations Alternate namesextensions, user content DefinitionMay 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. 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.
| |
| modifierExtension | ?! | 0..* | Extension | There are no (further) constraints on this element Element idMessageHeader.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content DefinitionMay 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. 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.
|
| event | Σ | 1..1 | CodingBinding | Element idMessageHeader.event Code for the event this message represents DefinitionCode that identifies the event this message represents and connects it with its definition. Events defined as part of the FHIR specification have the system value "http://hl7.org/fhir/message-events". Drives the behavior associated with this message. One of the message events defined as part of FHIR. messageHeaderEvents (required)Mappings
|
| id | 0..1 | string | There are no (further) constraints on this element Element idMessageHeader.event.id xml:id (or equivalent in JSON) Definitionunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Mappings
| |
| system | Σ | 0..1 | uri | Element idMessageHeader.event.system Identity of the terminology system DefinitionThe identification of the code system that defines the meaning of the symbol in the code. Need to be unambiguous about the source of the definition of the symbol. The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should de-reference to some definition that establish the system clearly and unambiguously.
|
| version | Σ | 0..1 | string | There are no (further) constraints on this element Element idMessageHeader.event.version Version of the system - if relevant DefinitionThe version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured. and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged. Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.
|
| code | Σ | 0..1 | code | Element idMessageHeader.event.code Symbol in syntax defined by the system DefinitionA symbol in syntax defined by the system.

|
| display | Σ | 0..1 | string | Element idMessageHeader.event.display Representation defined by the system DefinitionA representation of the meaning of the code in the system, following the rules of the system. Need to be able to carry a human-readable meaning of the code for readers that do not know the system.
|
| userSelected | Σ | 0..1 | boolean | There are no (further) constraints on this element Element idMessageHeader.event.userSelected If this coding was chosen directly by the user DefinitionIndicates that this coding was chosen by a user directly - i.e. off a pick list of available items (codes or displays). This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing. Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.
|
| destination | Σ | 0..* | BackboneElement | There are no (further) constraints on this element Element idMessageHeader.destination Message destination application(s) DefinitionThe destination application which the message is intended for. Indicates where message is to be sent for routing purposes. Allows verification of "am I the intended recipient". There SHOULD be at least one destination, but in some circumstances, the source system is unaware of any particular destination system.
|
| id | 0..1 | string | There are no (further) constraints on this element Element idMessageHeader.destination.id xml:id (or equivalent in JSON) Definitionunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
| |
| extension | 0..* | Extension | There are no (further) constraints on this element Element idMessageHeader.destination.extension Additional Content defined by implementations Alternate namesextensions, user content DefinitionMay be used to represent additional information that is not part of the basic definition of the element.

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.
