FHIR Extensions Pack
5.2.0-ballot - 5.2.0 Ballot - September 2024) International flag

FHIR Extensions Pack, published by HL7 International / FHIR Infrastructure. This guide is not an authorized publication; it is the continuous build for version 5.2.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-extensions/ and changes regularly. See the Directory of published versions

CodeSystem: Obligation Codes

Official URL: http://hl7.org/fhir/CodeSystem/obligation Version: 5.2.0-ballot
Standards status: Trial-use Maturity Level: 1 Computable Name: ObligationCodes
Other Identifiers: OID:2.16.840.1.113883.4.642.4.2123

Codes that describe application obligations for handling FHIR content. There are five kinds of codes in this code system:

  • Categorizer codes: ResourceProducerObligations, ResourcesExchangerObligations, and ResourceConsumerObligations which are used to construct value sets and indicate the contexts in which the obligations apply. Note that many applications will be producers, consumers, and potentially exchangers simultaneously, so there is no need to limit obligations to only one category. These are abstract and cannot be declared as obligations.
  • Qualifier codes: SHALL/SHOULD/MAY which convey the ‘strength’ of an obligation. These are also abstract and cannot be declared as obligations.
  • Generic codes - these describe abstract functional obligation behaviors applications may implement, but do not specify a specific strength. They may be organized in a hierarchy where one generic code specializes another. These are also abstract cannot be declared as obligations.
  • Leaf obligation codes - these are specific qualified obligations that can be declared by a data element and represent leaf-level obligations. They always inherit from a qualification concept and usually inherit from a functional code concept. These codes can be declared as obligations.
  • Composite codes - these specialise Leaf obligation codes, inheriting the expectations of multiple concrete obligations. They represent common or externally defined combinations of obligations for ease of reference. These codes can also be declared as obligations.

This Code system is referenced in the content logical definition of the following value sets:

Changes since version 1.0.0:

    Properties

    This code system defines the following properties for its concepts

    NameCodeURITypeDescription
    Not Selectable icon Added:not-selectable http://hl7.org/fhir/concept-properties#notSelectable boolean Codes with this property set are not intended to appear in instances. They are for grouping/subsetting purposes only.
    Parent icon Added:parent http://hl7.org/fhir/concept-properties#parent code
    qualifier icon Added:qualifier http://hl7.org/fhir/CodeSystem/obligation#qualifier code Indicates the level of adherence expected to the obligation concept
    converse icon Added:converse http://hl7.org/fhir/CodeSystem/obligation#converse code Indicates another obligation code with an opposite meaning to this one. A single obligation cannot list two converse codes and an application cannot satisfy both a code and its coverse (though if the obligation strength for both is SHOULD or MAY, an application could conform with both obligations by adhering to one and not the other).
    security-dependent icon Added:security-dependent http://hl7.org/fhir/CodeSystem/obligation#security-dependent boolean Obligation codes with this property set to true may be overridden by policies and regulations related to privacy and security, including patient consent. Testing of such obligations will need to take such considerations into account.

    Concepts

    This case-sensitive code system http://hl7.org/fhir/CodeSystem/obligation defines the following codes in a Is-A hierarchy:

    CodeDisplayDefinitionNot SelectableParent
    icon Added:SHALL SHALL

    The functional requirement is mandatory. Applications that do not implement this functional behavior are considered non-conformant.

    true
    icon Added:SHOULD SHOULD

    The functional requirement is a recommendation. Applications are strongly encouraged to implement this functional behavior, but are still conformant if they do not.

    true
    icon Added:MAY MAY

    The functional requirement is an option worthy of consideration but there is no expectation or recommendation associated with its use. NOTE: Elements not flagged with any obligation are intrinsically still 'MAY' (unless constraints dictate otherwise), but have not specifically been called out by the author as worthy of consideration.

    true
    ResourceProducerObligations ResourceProducerObligations

    Resource producers are applications that assembles resources in the first place. Resource producers may be a server, client, sender, receiver or some middleware device, and they may store the resource, or merely hand it on.

    icon Added:ResourceExchangerObligations ResourceExchangerObligations

    Exchangers do not produce or consume resources; they only pass the resource on. They may store the resource in a persistent store between reception and subsequent transfer. The generic FHIR servers are exchangers, as are most middleware systems. Note that Exchanger obligations may also be taken on by Producers or Consumers if they act as intermediaries between other systems or between systems and users.

    true
    ResourceConsumerObligations ResourceConsumerObligations

    Resource Consumers are applications that consume resources and do something with them, either displaying them to humans, transferring them to some other format for further re-use, or using them to drive some kind of application logic process AKA decision support. Resource Consumers often store resources, but do not need to, and whether resources are stored or not between receiving them and using them doesn't make any difference to the obligations

    icon Added:able-to-populate be able to populate

    Conformant applications producing resources SHALL/SHOULD/MAY be able to correctly populate this element. Notes: Typically, this means that an application needs to demonstrate during some conformance testing process that there are some conditions under which it populates the element with a correct value. (i.e. not a data-absent-reason or equivalent.) This obligation does not impose expectations on the circumstances in which the element will be sent, only that it can be in at least some situations.

    true ResourceProducerObligations
    icon Added:populate-if-known populate if known

    Conformant applications producing resources SHALL/SHOULD correctly populate this element if they know a value for the element, but it is acceptable if the system is unable to ever know a value for the element. Notes: This obligation does not impose a requirement to be able to know a value, unlike populate and able-to-populate which do. 'Knowing' an element means that a value for the element is available in memory, persistent store, or is otherwise available within the system claiming conformance.

    true ResourceProducerObligations
    icon Added:populate populate

    Conformant applications producing resources SHALL/SHOULD include this element if a value is known and allowed to be shared. Notes: This implementation obligation means that whenever the producer knows the correct value for an element, it populates it. This is NOT the same as cardinality, as a 'populate' element can be omitted if no data exists or the data that exists is prohibited from being shared.

    true populate-if-known, able-to-populate
    icon Added:in-narrative include in narrative

    Conformant applications SHALL/SHOULD/MAY ensure that this data element is represented in any human readable representation of a resource. Notes: When no value for an element is known, the producer populates the narrative with the content of any nested ElementDefinition.valueAlternatives extensions such as DataAbsentReason. If no particular reason is known or reportable, the element can simply be indicated as 'unknown' in the narrative.

    true ResourceProducerObligations
    icon Added:exclude-narrative exclude from narrative

    Conformant applications SHALL/SHOULD ensure that this data element is NOT represented in any human readable representation of a resource. Notes: This may be useful for profiles related to de-identified records

    true ResourceProducerObligations
    icon Added:user-input allow user input

    Conformant applications SHALL/SHOULD/MAY ensure that users can enter a value for this element during data input/capture. Notes: Exactly what form the input takes is not specified, but the expectation is that this is a value that comes from the user, and not implied internally by the application.

    true ResourceProducerObligations
    icon Added:explain populate or document irrelevance

    Documentation applicable to Conformant applications SHALL/SHOULD explain how this element is handled. Notes: this is really a rule about specifications, implying that another specification (which might be application documentation) either makes this element populate, or explains how the use cases that involve this element do not arise, or how they are handled. An example: IPA marks Patient.active must-handle and must-explain. Client applications must process Patient.active correctly if they see it, but many (though not all) specifications and/or applications ensure that Patient.active will never be false, and so it will never be populated e.g. MedMij in Netherlands prohibits use of Patient.active, and explains that it is never false.

    true ResourceProducerObligations
    icon Added:persist persist

    Conformant applications SHALL/SHOULD/MAY ensure that the value for this element is stored in a persistent data store. Notes: Exactly what the data store is not specified, nor how long it is stored for, but it is understood that the same value will be available in later exchanges

    true ResourceConsumerObligations, ResourceProducerObligations
    icon Added:no-alter not alter

    Conformant applications SHALL/SHOULD ensure that this element does not change between receiving and transfer. Notes: This does not mean that the element value cannot change, only that changing the element value for an element marked with this obligation moves an application from being an exchanger to a Consumer and a Producer, and those obligations apply

    true ResourceExchangerObligations
    icon Added:no-error not error if present

    Conformant applications SHALL/SHOULD accept resources containing any valid value for the element without error. Notes: Applications are still able to inform the user that a value cannot be processed correctly and may ignore the data, but applications aren't able to reject an instance merely because the element is present (which would be allowed for elements that do not have this obligation). A system MAY raise an error if the value provided is not valid or violates specific business rules. This obligation also applies to elements that only contain an extension in place of a value where (or equivalent), should either of these be allowed on the consumer obligations

    true ResourceConsumerObligations
    icon Added:reject-invalid reject invalid

    Conformant applications SHALL/SHOULD check that values for this element meet all data constraints asserted within the profile declaring this obligation. If validity issues are found, the system SHALL/SHOULD not accept the instance. Notes: This applies to validating the element with the obligation, but not resources referenced by it.

    true ResourceConsumerObligations
    icon Added:accept-invalid accept invalid

    Conformant applications SHALL/SHOULD accept data that does not meet all data constraints asserted within the profile declaring this obligation. This applies to non-valid constraints, not to non-valid syntax or failure to meet base resource validity expectations. Typically used when a system needs to be able to handle data that does not adhere to desired expectations (legacy data, test data, data undergoing authorship that is not yet complete, etc.)

    true ResourceConsumerObligations
    icon Added:handle correctly handle

    Conformant applications SHALL/SHOULD handle the meaning of this element correctly. Notes: this rule is vague in that doesn't specify any particular handling of the element. But it's important because an application that ignores this element is non-conformant. A good example would be a status code of 'entered-in-error' - how exactly a Resource Consumer handles this depends on the use case etc., but the application can never simply ignore such a status code. Note that whether the resource or information from it is stored for later use is irrelevant - when the resource or information in it is processed, the consequences of the element are considered. That may mean not retaining the information for later use, or informing the user, etc. Typically, this obligation marks that there are known patient safety issues that can arise if the element is ignored. Implementers should pay particular attention to the possible range of values for the element from a safety perspective.

    true ResourceConsumerObligations
    icon Added:display display

    Conformant applications SHALL/SHOULD/MAY display the value of this element when presenting the data from the resource to a human user. Notes: exactly how it is displayed is not specified, but it means that a human looking at the content of the resource is made aware of the value of the element so that they can consider the meaning of the resource

    true handle
    icon Added:process process

    Conformant applications SHALL/SHOULD/MAY consider the value of this element when processing the resource as specified by the IG. Notes: this implies that the IG that specifies this obligation provides details about what processing is to be performed, and the obligation specifially relates to the processing specified in the IG of any ElementDefinition.valueAlternatives extensions as well as the value (or other extensions explicitly declared beneath the element in the profile containing the obligation. Examples might include consideration in decision support, consideration in claims evaluation, etc.

    true handle
    icon Added:print print

    Conformant applications SHALL/SHOULD/MAY print the value of this element somewhere. Notes: The form of the printing is not specified. A profile using this value SHALL explain the nature of the printing requirement somehow

    true handle
    icon Added:ignore ignore

    Conformant applications SHALL/SHOULD/MAY not make any use of the value of this element if received.

    true ResourceConsumerObligations
    icon Added:SHALL:able-to-populate SHALL be able to populate

    Conformant applications producing resources SHALL be able to correctly populate this element. Notes: Typically, this means that an application needs to demonstrate during some conformance testing process that there are some conditions under which it populates the element with a correct value. (i.e. not a data-absent-reason or equivalent.) This obligation does not impose expectations on the circumstances in which the element will be sent, only that it can be in at least some situations.

    able-to-populate
    icon Added:SHOULD:able-to-populate SHOULD be able to populate

    Conformant applications producing resources SHOULD be able to correctly populate this element. Notes: Typically, this means that an application needs to demonstrate during some conformance testing process that there are some conditions under which it populates the element with a correct value. (i.e. not a data-absent-reason or equivalent.) This obligation does not impose expectations on the circumstances in which the element will be sent, only that it shold be in at least some situations.

    able-to-populate
    icon Added:MAY:able-to-populate MAY be able to populate

    Conformant applications producing resources MAY be able to correctly populate this element. Notes: Typically, this means that an application needs to demonstrate during some conformance testing process that there are some conditions under which it populates the element with a correct value. (i.e. not a data-absent-reason or equivalent.) This obligation does not impose expectations on the circumstances in which the element will be sent, only that it may be in at least some situations. This is a null statement and is the default behavior for originating systems if other obligations are not specified.

    able-to-populate
    icon Added:SHALL:populate-if-known SHALL populate if known

    Conformant applications producing resources SHALL correctly populate this element if they know a value for the element, but it is acceptable if the system is unable to ever know a value for the element. Notes: This obligation does not impose a requirement to be able to know a value, unlike populate and able-to-populate which do. 'Knowing' an element means that a value for the element is available in memory, persistent store, or is otherwise available within the system claiming conformance.

    populate-if-known
    icon Added:SHOULD:populate-if-known SHOULD populate if known

    Conformant applications producing resources SHOULD correctly populate this element if they know a value for the element, but it is acceptable if the system is unable to ever know a value for the element. Notes: This obligation does not impose a requirement to be able to know a value, unlike populate and able-to-populate which do. 'Knowing' an element means that a value for the element is available in memory, persistent store, or is otherwise available within the system claiming conformance.

    populate-if-known
    icon Added:SHALL:populate SHALL populate

    Conformant applications producing resources SHALL include this element if a value is known and allowed to be shared. Notes: This implementation obligation means that whenever the producer knows the correct value for an element, it populates it. This is NOT the same as cardinality, as a 'populate' element can be omitted if no data exists or the data that exists is prohibited from being shared.

    SHALL:able-to-populate, populate
    icon Added:SHOULD:populate SHOULD populate

    Conformant applications producing resources SHOULD include this element if a value is known and allowed to be shared. Notes: This implementation obligation means that whenever the producer knows the correct value for an element, it should populate it. This is NOT the same as cardinality, as a 'populate' element can be omitted if no data exists or the data that exists is prohibited from being shared.

    SHOULD:able-to-populate, populate
    icon Added:SHALL:in-narrative SHALL include in narrative

    Conformant applications SHALL ensure that this data element is represented in any human readable representation of a resource. Notes: When no value for an element is known, the producer populates the narrative with the content of any nested ElementDefinition.valueAlternatives extensions such as DataAbsentReason. If no particular reason is known or reportable, the element can simply be indicated as 'unknown' in the narrative.

    in-narrative
    icon Added:SHOULD:in-narrative SHOULD include in narrative

    Conformant applications SHOULD ensure that this data element is represented in any human readable representation of a resource. Notes: When no value for an element is known, the producer populates the narrative with the content of any nested ElementDefinition.valueAlternatives extensions such as DataAbsentReason. If no particular reason is known or reportable, the element can simply be indicated as 'unknown' in the narrative.

    in-narrative
    icon Added:MAY:in-narrative MAY include in narrative

Notes: When no value for an element is known, the producer populates the narrative with the content of any nested ElementDefinition.valueAlternatives extensions such as DataAbsentReason. If no particular reason is known or reportable, the element can simply be indicated as 'unknown' in the narrative.

    in-narrative
    icon Added:SHALL:exclude-narrative SHALL exclude from narrative

    Conformant applications SHALL ensure that this data element is NOT represented in any human readable representation of a resource. Notes: This may be useful for profiles related to de-identified records

    exclude-narrative
    icon Added:SHOULD:exclude-narrative SHOULD exclude from narrative

    Conformant applications SHOULD ensure that this data element is NOT represented in any human readable representation of a resource. Notes: This may be useful for profiles related to de-identified records

    exclude-narrative
    icon Added:SHALL:user-input SHALL allow user input

    Conformant applications SHALL ensure that users can enter a value for this element during data input/capture. Notes: Exactly what form the input takes is not specified, but the expectation is that this is a value that comes from the user, and not implied internally by the application.

    user-input
    icon Added:SHOULD:user-input SHOULD allow user input

    Conformant applications SHOULD ensure that users can enter a value for this element during data input/capture. Notes: Exactly what form the input takes is not specified, but the expectation is that this is a value that comes from the user, and not implied internally by the application.

    user-input
    icon Added:MAY:user-input MAY allow user input

    user-input
    icon Added:SHALL:explain SHALL populate or document irrelevance

    Documentation applicable to Conformant applications SHALL explain how this element is handled. Notes: this is really a rule about specifications, implying that another specification (which might be application documentation) either makes this element populate, or explains how the use cases that involve this element do not arise, or how they are handled. An example: IPA marks Patient.active must-handle and must-explain. Client applications must process Patient.active correctly if they see it, but many (though not all) specifications and/or applications ensure that Patient.active will never be false, and so it will never be populated e.g. MedMij in Netherlands prohibits use of Patient.active, and explains that it is never false.

    persist
    icon Added:SHOULD:persist SHOULD persist

    persist
    icon Added:SHALL:no-alter SHALL not alter

    Conformant applications SHALL ensure that this element does not change between receiving and transfer. Notes: This does not mean that the element value cannot change, only that changing the element value for an element marked with this obligation moves an application from being an exchanger to a Consumer and a Producer, and those obligations apply

    no-alter
    icon Added:SHOULD:no-alter SHOULD not alter

    Conformant applications SHOULD ensure that this element does not change between receiving and transfer. Notes: This does not mean that the element value cannot change, only that changing the element value for an element marked with this obligation moves an application from being an exchanger to a Consumer and a Producer, and those obligations apply

    no-alter
    icon Added:MAY:alter MAY alter

    Conformant applications MAY choose to alter this element value. Notes: this is really a null-statement - it's the default rule for an application. It's defined here to allow a specification to be explicit that it isn't conveying obligations for resource producers

    ResourceExchangerObligations
    icon Added:SHALL:no-error SHALL not error if present

    Conformant applications SHALL accept resources containing any valid value for the element without error. Notes: Applications are still able to inform the user that a value cannot be processed correctly and may ignore the data, but applications aren't able to reject an instance merely because the element is present (which would be allowed for elements that do not have this obligation). A system MAY raise an error if the value provided is not valid or violates specific business rules. This obligation also applies to elements that only contain an extension in place of a value where (or equivalent), should either of these be allowed on the consumer obligations

This applies to non-valid constraints, not to non-valid syntax or failure to meet base resource validity expectations. Typically used when a system needs to be able to handle data that does not adhere to desired expectations (legacy data, test data, data undergoing authorship that is not yet complete, etc.)

    accept-invalid
    icon Added:SHOULD:accept-invalid SHOULD accept invalid

    Conformant applications SHOULD accept data that does not meet all data constraints asserted within the profile declaring this obligation.
