5. Task.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. Task.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. Task.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. Task.meta.profile
Definition

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

Control1..*

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

Control0..0
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
11. Task.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
12. Task.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
13. Task.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
14. Task.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
15. Task.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.

17. Task.extension:groupIdentifier
SliceNamegroupIdentifier
Definition

This is the common identifier that represents a paper order. It may be shared by multiple Task instances for various Medication Orders, reflecting multiple requests that are authorized simultaneously for a patient by a single prescriber

Control1..1
TypeExtension(Task Group Identifier) (Extension Type: Identifier)
Must Supporttrue
Comments

Usage Note: This business identifier is assigned by the sending application and is used to group tasks together that need to be processed and managed together. The following scenarios provide further detail:

Scenario 1) Single Task allowed within a Bundle: There are some business scenarios where a given task will be managed individually and only a single task is allowed in a bundle. This is true for the Adapt (p170) and the Pharmacist Prescribe (p190). Multiple tasks of the same type are not allowed, nor are any other task type.

Scenario 2) Single Task is sent. For any task type, the source system may send a single task within the bundle.

Scenario 3) In either scenario 1 or 2, the task will be assigned its own Group Identifier and will be handled as a group of one.

Scenario 4) Bundle restricted to same task type only: There are cases when only tasks of the same type can be grouped together. This is true for the cancel request (e140), Dispense Notifications (p200), Cancel RX Dispense Notification (p210). In this scenario, no other task types are allowed within the bundle.

Scenario 5) Same or Mixed Task Types within a single group: There are cases when either all the tasks within a group happen to have the same task type (p160) which are not necessary restricted due to 4 or certain task types that are different can be grouped together. This is true for new (e110) and renewal (e120) where these are part of the same prescription. Another scenario is that renewal responses (e161, e162, e163, e164) may be sent with an e110 and/or an e120.

Scenario 6) In either scenario 4 and 5, the same Group Identifier must be assigned to the multiple tasks as they are all part of the same group. All task resources sharing a Group Identifier must be transmitted in the same message bundle and should be treated as a group by the receiving system.

Scenario 7) The p160 task type can only be sent within it's own bundle.

Multiple Group Identifiers within the same Bundle is not allowed.

The Task.extension:groupIdentifier.valueIdentifier.system element will be an OID of the form [Vendor root].[Application instance node].3 expressed as a uri (e.g. urn:oid:1.2.3.4). The branch “.3” is appended to create a unique namespace for the Group Identifer. The Task.extension:groupIdentifier.valueIdentifier.value element will be assigned by the sending system and must be a unique business identifier.

64. Task.type.coding:taskCode.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)

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries.
