Definitions for the profile-messageheader-9xx Profile.

1. MessageHeader
Definition

The 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.

Control0..*

Max Length0
2. MessageHeader.id
Definition

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

Control1..1
Typeid
Must Supporttrue
Comments

Usage Note: This value is assigned by the system that creates a bundle and is unique to the specific message instance of the bundle and the uniqueness of this value will be validated by the PrescribeIT® service. This value is sometimes referenced in error messages.

Max Length0
3. MessageHeader.meta
Definition

The 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.

Control0..1
TypeMeta
Must Supporttrue
Comments

Max Length0
4. MessageHeader.meta.id
Definition

unique id for the element within a resource (for internal references).

Control0..1
Typeid
Max Length0
5. MessageHeader.meta.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. 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.

Control0..*
TypeExtension
Alternate Namesextensions, user content
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.

Max Length0
6. MessageHeader.meta.versionId
Definition

The version specific identifier, as it appears in the version portion of the URL. This values changes when the resource is created, updated, or deleted.

Control0..1
Typeid
Comments

The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.

Max Length0
7. MessageHeader.meta.lastUpdated
Definition

When the resource last changed - e.g. when the version changed.

Control0..1
Typeinstant
Comments

This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant.

Max Length0
8. MessageHeader.meta.profile
Definition

A list of profiles StructureDefinitions that this resource claims to conform to. The URL is a reference to StructureDefinition.url.

Control0..*
Typeuri
Must Supporttrue
Comments

It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set.

Max Length0
9. MessageHeader.meta.security
Definition

Security labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure.

Control0..*
BindingThe codes SHALL be taken from All Security Labels; other codes may be used where these codes are not suitable Security Labels from the Healthcare Privacy and Security Classification System.
TypeCoding
Comments

The security labels can be updated without changing the stated version of the resource The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored.

Max Length0
10. MessageHeader.meta.tag
Definition

Tags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource.

Control0..*
Binding

Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones"

TypeCoding
Comments

The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored.

Max Length0
11. MessageHeader.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.

Control0..1
Typeuri
Is Modifiertrue
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 as much as possible.

Max Length0
12. MessageHeader.language
Definition

The base language in which the resource is written.

Control0..1
BindingThe codes SHALL be taken from http://tools.ietf.org/html/bcp47 A human language.
Typecode
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).

Max Length0
13. MessageHeader.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.

Control0..1 This element is affected by the following invariants: dom-1
TypeNarrative
Alternate Namesnarrative, html, xhtml, display
Comments

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative.

Max Length0
14. MessageHeader.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.

Control0..*
TypeResource
Alternate Namesinline resources, anonymous resources, contained 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.

Max Length0
15. MessageHeader.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.

16. MessageHeader.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.

Max Length0
Fixed Valuehttps://fhir.infoway-inforoute.ca/CodeSystem/sharedmessageevents
22. MessageHeader.event.version
Definition

The 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.

NoteThis is a business versionId, not a resource version id (see discussion)
Control0..1
Typestring
Comments

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.

Max Length0

Max Length0
25. MessageHeader.event.userSelected
Definition

Indicates that this coding was chosen by a user directly - i.e. off a pick list of available items (codes or displays).

Control0..1
Typeboolean
Requirements

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.

Comments

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.
