#### StructureDefinition: ADHA Core OperationOutcome - Detailed Descriptions

Definitions for the dh-operationoutcome-core-1 Profile.

1. OperationOutcome
Definition | A collection of error, warning, or information messages that result from a system action.
Control | 0..*
Comments | Can result from the failure of a REST call or be part of the response message returned from a request message.
2. OperationOutcome.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Control | 0..1
Type | id
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.
3. OperationOutcome.meta
Definition | 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.
Control | 0..1
Type | Meta
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
4. OperationOutcome.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. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Control | 0..1
Type | uri
Is Modifier | 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. 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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. OperationOutcome.language
Definition | The base language in which the resource is written.
Control | 0..1
Binding | The codes SHOULD be taken from CommonLanguages A human language
Additional Bindings | Purpose
AllLanguages | Max Binding
Type | code
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).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. OperationOutcome.text
Definition | 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.
Control | 0..1
Type | Narrative
Alternate Names | narrativehtmlxhtmldisplay
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 information is added later.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. OperationOutcome.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.
Control | 0..*
Type | Resource
Alternate Names | inline resourcesanonymous resourcescontained 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. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.
8. OperationOutcome.extension
Definition | May be used to represent additional information that is not part of the basic definition of the resource. 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.
Control | 0..*
Type | Extension
Alternate Names | extensionsuser 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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
9. OperationOutcome.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 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).
Control | 0..*
Type | Extension
Is Modifier | true
Requirements | 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.

14. OperationOutcome.issue.severity
Definition | Indicates whether the issue indicates a variation from successful processing.
Control | 1..1
Binding | The codes SHALL be taken from IssueSeverity How the issue affects the success of the action
Type | code
Must Support | true
Requirements | Indicates how relevant the issue is to the overall success of the action.
Comments | This is labeled as "Is Modifier" because applications should not confuse hints and warnings with errors.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
15. OperationOutcome.issue.code
Definition | Describes the type of the issue. The system that creates an OperationOutcome SHALL choose the most applicable code from the IssueType value set, and may additional provide its own code for the error in the details element.
Control | 1..1
Binding | The codes SHALL be taken from IssueType A code that describes the type of issue
Type | code
Must Support | true
Requirements | Expresses the issue in a human and computer-friendly way, allowing the requesting system to behave differently based on the type of issue. The required element provides a base level of computable interoperability across all systems for processing an outcome, allowing systems to respond appropriately regardless of the internal system error codes returned.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
16. OperationOutcome.issue.details
Definition | Additional details about the error. This may be a text description of the error or a system code that identifies the error.
Control | 1..1
Binding | For example codes, see OperationOutcomeCodes A code that provides details as the exact issue
Type | CodeableConcept
Must Support | true
Comments | A human readable description of the error issue SHOULD be placed in details.text.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
17. OperationOutcome.issue.diagnostics
Definition | Additional diagnostic information about the issue.
Control | 0..1
Type | string
Must Support | true
Comments | This may be a description of how a value is erroneous, a stack dump to help trace the issue or other troubleshooting information.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
18. OperationOutcome.issue.location
Definition | This element is deprecated because it is XML specific. It is replaced by issue.expression, which is format independent, and simpler to parse. For resource issues, this will be a simple XPath limited to element names, repetition indicators and the default child accessor that identifies one of the elements in the resource that caused this issue to be raised. For HTTP errors, will be "http." + the parameter name.
Control | 0..*
Type | string
Requirements | Allows systems to highlight or otherwise guide users to elements implicated in issues to allow them to be fixed more easily.
Comments | The root of the XPath is the resource or bundle that generated OperationOutcome. Each XPath SHALL resolve to a single node. This element is deprecated, and is being replaced by expression.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
19. OperationOutcome.issue.expression
Definition | A simple subset of FHIRPath limited to element names, repetition indicators and the default child accessor that identifies one of the elements in the resource that caused this issue to be raised.
Control | 0..*
Type | string
Requirements | Allows systems to highlight or otherwise guide users to elements implicated in issues to allow them to be fixed more easily.
Comments | The root of the FHIRPath is the resource or bundle that generated OperationOutcome. Each FHIRPath SHALL resolve to a single node.
