Indicates the start and/or end of the period of time when the GFE bundle should be provided.

If a previous request was completed or cancelled that largely represents this current task it may be useful for GFE contributors to be able to refer to the previous request. This may happen when something about a GFE collection request changes so much that it requires re-issuing the request by cancelling the first one and creating a new one. GFE contributors may want to refer back to the previous request in order to help them populate a response to the new one.

Generally this will be a reference to a Practitioner or Organization resource residing on the Coordination Platform. If there is a need to express contact information that is specific to the request, and therefore is not included in the information on the Coordination Platform, the reference should point to a server and resource that does not have additional authentication or or authorization requirements.

Contained or referenced request information bundle made available to all GFE contributors that includes information about the products and or services requested and other supporting information, such as Conditions, Observations, and notes

A task to be performed.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

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.

An Extension

Optional Extension Element - found in all resources.

Indicates the start and/or end of the period of time when the GFE bundle should be provided.

An Extension

Source of the definition for the extension code - a logical name or a URL.

The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

The start of the period. The boundary is inclusive.

If the low element is missing, the meaning is that the low boundary is not known.

The end of the period. If the end of the period is missing, it means no end was known or planned at the time the instance was created. The start may be in the past, and the end date in the future, which means that period is expected/planned to end at that time.

The high value includes any matching date/time. i.e. 2012-02-03T10:00:00 is in a period that has an end value of 2012-02-03.

Instant from which the request is being initiated.

Planned period of service the request is about

Completed or terminated task(s) whose function is taken by this new task.

If a previous request was completed or cancelled that largely represents this current task it may be useful for GFE contributors to be able to refer to the previous request. This may happen when something about a GFE collection request changes so much that it requires re-issuing the request by cancelling the first one and creating a new one. GFE contributors may want to refer back to the previous request in order to help them populate a response to the new one.

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 and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

The business identifier for this task.

The business identifier for this task.

The purpose of this identifier.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Identifies the purpose for this identifier, if known .

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

Allows users to make use of identifiers when the identifier system is not known.

Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

Identifier.system is always case sensitive.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Task that this particular task is part of.

This should usually be 0..1.

Allows tasks to be broken down into sub-steps (and this division can occur independent of the original task).

The current status of the task.

These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks.

An explanation as to why this task is held, failed, was refused, etc.

This applies to the current status. Look at the history of the task to see reasons for past statuses.

Indicates the "level" of actionability associated with the Task, i.e. i+R[9]Cs this a proposed task, a planned task, an actionable task, etc.

This element is immutable. Proposed tasks, planned tasks, etc. must be distinct instances.

In most cases, Tasks will have an intent of "order".

Distinguishes whether the task is a proposal, plan or full order.

A name or code (or both) briefly describing what the task involves.

The title (eg "My Tasks", "Outstanding Tasks for Patient X") should go into the code.

Codes to identify what the task involves. These will typically be specific to a particular workflow.

The creator of the task.

Generally this will be a reference to a Practitioner or Organization resource residing on the Coordination Platform. If there is a need to express contact information that is specific to the request, and therefore is not included in the information on the Coordination Platform, the reference should point to a server and resource that does not have additional authentication or or authorization requirements.

Identifies who created this task. May be used by access control mechanisms (e.g., to ensure that only the creator can cancel a task).

The kind of participant that should perform the task.

The type(s) of task performers allowed.

Use to distinguish tasks on different activity queues.

Individual organization or Device currently responsible for task execution.

Tasks may be created with an owner not yet identified.

Identifies who is expected to perform this task.

A description or code indicating why this task needs to be performed.

This should only be included if there is no focus or if it differs from the reason indicated on the focus.

If the Task.focus is a request resource and the task is seeking fulfillment (i.e. is asking for the request to be actioned), this element identifies any limitations on what parts of the referenced request should be actioned.

Sometimes when fulfillment is sought, you don't want full fulfillment.

Additional information that may be needed in the execution of the task.

Contained or referenced request information bundle made available to all GFE contributors that includes information about the products and or services requested and other supporting information, such as Conditions, Observations, and notes

Resources and data used to perform the task. This data is used in the business logic of task execution, and is stored separately because it varies between workflows.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 can 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.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

A code or description indicating how the input is intended to be used as part of the task execution.

If referencing a BPMN workflow or Protocol, the "system" is the URL for the workflow definition and the code is the "name" of the required input.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Comparison source", "Applicable consent", "Concomitent Medications", etc.

Inputs are named to enable task automation to bind data and pass it from one task to the next.

The value of the input parameter as a basic type.

Outputs produced by the Task.

Resources and data produced during the execution the task. This data is generated by the business logic of task execution, and is stored separately because it varies between workflows.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants.

The name of the Output parameter.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Identified issues", "Preliminary results", "Filler order", "Final results", etc.

Outputs are named to enable task automation to bind data and pass it from one task to the next.

The value of the Output parameter as a basic type.

Task outputs can take any form.

A task to be performed.

The 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.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

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.

The 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.

A human-readable narrative that contains a summary of the resource and can 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 information is added later.

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.

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.

An Extension

Optional Extension Element - found in all resources.

Indicates the start and/or end of the period of time when the GFE bundle should be provided.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Enables a formal definition of how he task is to be performed (e.g. using BPMN, BPEL, XPDL or other formal notation to be associated with a task), enabling automation.

BasedOn refers to a higher-level authorization that triggered the creation of the task. It references a "request" resource such as a ServiceRequest, MedicationRequest, ServiceRequest, CarePlan, etc. which is distinct from the "request" resource the task is seeking to fulfill. This latter resource is referenced by FocusOn. For example, based on a ServiceRequest (= BasedOn), a task is created to fulfill a procedureRequest ( = FocusOn ) to collect a specimen from a patient.

The date and time of last modification to this task.

Used along with history to track task activity and time in a particular task state. This enables monitoring and management.

The creator of the task.

Generally this will be a reference to a Practitioner or Organization resource residing on the Coordination Platform. If there is a need to express contact information that is specific to the request, and therefore is not included in the information on the Coordination Platform, the reference should point to a server and resource that does not have additional authentication or or authorization requirements.

Identifies who created this task. May be used by access control mechanisms (e.g., to ensure that only the creator can cancel a task).

The kind of participant that should perform the task.

The type(s) of task performers allowed.

Use to distinguish tasks on different activity queues.

Individual organization or Device currently responsible for task execution.

Tasks may be created with an owner not yet identified.

Identifies who is expected to perform this task.

Principal physical location where the this task is performed.

Ties the event to where the records are likely kept and provides context around the event occurrence (e.g. if it occurred inside or outside a dedicated healthcare setting).

A description or code indicating why this task needs to be performed.

This should only be included if there is no focus or if it differs from the reason indicated on the focus.

A resource reference indicating why this task needs to be performed.

Tasks might be justified based on an Observation, a Condition, a past or planned procedure, etc. This should only be included if there is no focus or if it differs from the reason indicated on the focus. Use the CodeableConcept text element in Task.reasonCode if the data is free (uncoded) text.

Insurance plans, coverage extensions, pre-authorizations and/or pre-determinations that may be relevant to the Task.

Free-text information captured about the task as it progresses.

Links to Provenance records for past versions of this Task that identify key state transitions or updates that are likely to be relevant to a user looking at the current version of the task.

This element does not point to the Provenance associated with the current version of the resource - as it would be created after this version existed. The Provenance for the current version can be retrieved with a _revinclude.

If the Task.focus is a request resource and the task is seeking fulfillment (i.e. is asking for the request to be actioned), this element identifies any limitations on what parts of the referenced request should be actioned.

Sometimes when fulfillment is sought, you don't want full fulfillment.

Additional information that may be needed in the execution of the task.

Resources and data used to perform the task. This data is used in the business logic of task execution, and is stored separately because it varies between workflows.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

If referencing a BPMN workflow or Protocol, the "system" is the URL for the workflow definition and the code is the "name" of the required input.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Comparison source", "Applicable consent", "Concomitent Medications", etc.

Inputs are named to enable task automation to bind data and pass it from one task to the next.

The value of the input parameter as a basic type.

Outputs produced by the Task.

Resources and data produced during the execution the task. This data is generated by the business logic of task execution, and is stored separately because it varies between workflows.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 can 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.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

The name of the Output parameter.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Identified issues", "Preliminary results", "Filler order", "Final results", etc.

Outputs are named to enable task automation to bind data and pass it from one task to the next.

The value of the Output parameter as a basic type.

Task outputs can take any form.
