GPConnect-Task-1 (Task)	I		Task	There are no (further) constraints on this element Element id Task Short description A task to be performed Definition A task to be performed. Data type Task Constraints 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()` inv-1: Last modified date must be greater than or equal to authored-on date. `lastModified.exists().not() or authoredOn.exists().not() or lastModified >= authoredOn` Mappings rim: Entity. Role, or Act workflow: Request, Event rim: ControlAct[moodCode=INT] w5: workflow.order
id	Σ	0..1	id	There are no (further) constraints on this element Element id Task.id Short description Logical id of this artifact Definition The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. Comments The only time that a resource does not have an id is when it is being submitted to the server using a create operation. Data type id Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a
meta	Σ	0..1	Meta	There are no (further) constraints on this element Element id Task.meta Short description Metadata about the resource 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. Data type Meta Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a rim: N/A
implicitRules	Σ ?!	0..1	uri	There are no (further) constraints on this element Element id Task.implicitRules Short description A set of rules under which this content was created 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. 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. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a
language		0..1	codeBinding	There are no (further) constraints on this element Element id Task.language Short description Language of the resource content Definition The base language in which the resource is written. 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). Data type code Binding A human language. Common Languages (extensible) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a
text	I	0..1	Narrative	There are no (further) constraints on this element Element id Task.text Short description Text summary of the resource, for human interpretation Alternate names narrative, html, xhtml, display 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. 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. Data type Narrative Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a rim: N/A rim: Act.text?
contained		0..*	Resource	There are no (further) constraints on this element Element id Task.contained Short description Contained, inline Resources Alternate names inline resources, anonymous resources, contained resources 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. 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. Data type Resource Mappings rim: Entity. Role, or Act rim: N/A
extension	I	0..*	Extension	There are no (further) constraints on this element Element id Task.extension Short description Additional Content defined by implementations Alternate names extensions, user content 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. 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. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
modifierExtension	?! I	0..*	Extension	There are no (further) constraints on this element Element id Task.modifierExtension Short description Extensions that cannot be ignored Alternate names extensions, user content 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. 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.

basedOn	Σ I	0..*	Reference(Resource \| GPConnect-Task-1)	Element id Task.basedOn Short description Request fulfilled by this task Definition BasedOn refers to a higher-level authorization that triggered the creation of the task. It references a "request" resource such as a ProcedureRequest, MedicationRequest, ProcedureRequest, CarePlan, etc. which is distinct from the "request" resource the task is seeking to fulfil. This latter resource is referenced by FocusOn. For example, based on a ProcedureRequest (= BasedOn), a task is created to fulfil a procedureRequest ( = FocusOn ) to collect a specimen from a patient. Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Data type Reference(Resource \| GPConnect-Task-1) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %resource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Request.basedOn, Definition.basedOn rim: .outboundRelationship[typeCode=FLFS].target[moodCode=INT]
groupIdentifier	Σ	0..1	Identifier	There are no (further) constraints on this element Element id Task.groupIdentifier Short description Requisition or grouper id Definition An identifier that links together multiple tasks and other requests that were created in the same context. Requirements Billing and/or reporting can be linked to whether multiple requests were created as a single unit. Data type Identifier Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a v2: CX / EI (occasionally, more often EI maps to a resource id or a URL) rim: II - see see identifier pattern at http://wiki.hl7.org/index.php?title=Common_Design_Patterns#Identifier_Pattern for relevant discussion.

partOf	Σ I	0..*	Reference(Task \| GPConnect-Task-1)	Element id Task.partOf Short description Composite task Definition Task that this particular task is part of. Requirements Allows tasks to be broken down into sub-steps (and this division can occur independent of the original task). Comments This should usually be 0..1. Data type Reference(Task \| GPConnect-Task-1) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %resource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.partOf rim: .inboundRelationship[typeCode=COMP].source[moodCode=INT]
status	Σ	1..1	codeBinding	There are no (further) constraints on this element Element id Task.status Short description draft \| requested \| received \| accepted \| + Definition The current status of the task. Requirements These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks. Comments Note that FHIR strings may not exceed 1MB in size Data type code Binding The current status of the task.

statusReason	Σ	0..1	CodeableConcept	There are no (further) constraints on this element Element id Task.statusReason Short description Reason for current status Definition An explanation as to why this task is held, failed, was refused, etc. Comments This applies to the current status. Look at the history of the task to see reasons for past statuses. Data type CodeableConcept Binding Codes to identify the reason for current status. These will typically be specific to a particular workflow.

businessStatus	Σ	0..1	CodeableConcept	There are no (further) constraints on this element Element id Task.businessStatus Short description E.g. "Specimen collected", "IV prepped" Definition Contains business-specific nuances of the business state. Requirements There's often a need to track substates of a task - this is often variable by specific workflow implementation. Comments Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. Data type CodeableConcept Binding The domain-specific business-contextual sub-state of the task. For example: "Blood drawn", "IV inserted", "Awaiting physician signature", etc. (unbound) (example) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a v2: CE/CNE/CWE rim: CD orim: fhir:CodeableConcept rdfs:subClassOf dt:CD rim: .inboundRelationship[typeCode=SUBJ].source[classCode=OBS, moodCode=EVN, code="business status"]
intent	Σ	1..1	codeBinding	There are no (further) constraints on this element Element id Task.intent Short description proposal \| plan \| order + Definition Indicates the "level" of actionability associated with the Task. I.e. Is this a proposed task, a planned task, an actionable task, etc. Comments This element is immutable. Proposed tasks, planned tasks, etc. must be distinct instances. In most cases, Tasks will have an intent of "order". Data type code Binding Distinguishes whether the task is a proposal, plan or full order RequestIntent (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a workflow: Request.intent rim: .moodCode w5: class

focus	Σ I	0..1	Reference(Resource \| GPConnect-Task-1)	Element id Task.focus Short description What task is acting on Definition The request being actioned or the resource being manipulated by this task. Requirements Used to identify the thing to be done. Comments If multiple resources need to be manipulated, use sub-tasks. (This ensures that status can be tracked independently for each referenced resource.). Data type Reference(Resource \| GPConnect-Task-1) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %resource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) rim: .outboundRelationship[typeCode=SUBJ].target w5: what
for	Σ I	0..1	Reference(Resource \| GPConnect-Task-1)	Element id Task.for Short description Beneficiary of the Task Alternate names Patient Definition The entity who benefits from the performance of the service specified in the task (e.g., the patient). Requirements Used to track tasks outstanding for a beneficiary. Do not use to track the task owner or creator (see owner and creator respectively). This can also affect access control. Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Data type Reference(Resource \| GPConnect-Task-1) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %resource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Request.subject, Event.subject rim: .participation[typeCode=RCT].role w5: who.focus

Requirements For some tasks it may be important to know the link between the task or episode of care the task originated within. Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

executionPeriod	Σ I	0..1	Period	There are no (further) constraints on this element Element id Task.executionPeriod Short description Start and end time of execution Definition Identifies the time action was first taken against the task (start) and/or the time final action was taken against the task prior to marking it as completed (end). Comments This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval\|Duration. Data type Period Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` per-1: If present, start SHALL have a lower value than end `start.empty() or end.empty() or (start <= end)` Mappings rim: n/a v2: DR rim: IVL<TS>[lowClosed="true" and highClosed="true"] or URG<TS>[lowClosed="true" and highClosed="true"] workflow: Event.occurrence[x] rim: .effectiveTime w5: when.done

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. 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.

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.

Comments References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

reference	Σ I	1..1	string	There are no (further) constraints on this element Element id Task.requester.agent.reference Short description Literal reference, Relative, internal or absolute URL Definition A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Comments 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. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

identifier	Σ	0..1	Identifier	There are no (further) constraints on this element Element id Task.requester.agent.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the other resource. This is used when there is no way to reference the other resource directly, either because the entity is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Summary	True
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.

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.

Definition	An identifier for the other resource. This is used when there is no way to reference the other resource directly, either because the entity is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.
Cardinality	0...1
Type	Identifier
Summary	True
Comments	When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

This element may need to be included in narrative because of the potential for modifying information. Annotations SHOULD NOT be used to communicate "modifying" information that could be computable. (This is a SHOULD because enforcing user behavior is nearly impossible).

Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference\n\nApplications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it." />

Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred.

For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred.

            <comment value="When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference\n\nApplications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it." />

            <comment value="When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference\n\nApplications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it." />

For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred.

For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. \n\nWhen both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference\n\nApplications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.",
