## Resource Profile: QICoreBodyStructure - Detailed Descriptions

Definitions for the qicore-bodystructure resource profile.

1. BodyStructure
Definition | Record details about an anatomical structure. This resource may be used when a coded concept does not provide the necessary detail needed for the use case.
Control | 0..*
Alternate Names | anatomical location
Invariants | Defined on this element dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (: contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).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-5: If a resource is contained in another resource, it SHALL NOT have a security label (: contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (: text.`div`.exists())
2. BodyStructure.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 | string
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. BodyStructure.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. BodyStructure.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. BodyStructure.language
Definition | The base language in which the resource is written.
Control | 0..1
Binding | The codes SHOULD be taken from CommonLanguages Max Binding: AllLanguages A human language.
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. BodyStructure.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 | narrative, html, xhtml, display
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. BodyStructure.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 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. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.
8. BodyStructure.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 | extensions, 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.
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. BodyStructure.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.
Alternate Names | extensions, 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.
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())
10. BodyStructure.identifier
Definition | Identifier for this instance of the anatomical structure.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
11. BodyStructure.active
Definition | Whether this body site is in active use.
Control | 1..1
Type | boolean
Is Modifier | true
Must Support | true
Requirements | Need to be able to mark a body site entry as not to be used because it was created in error.
Comments | This element is labeled as a modifier because it may be used to mark that the resource was created in error.
Meaning if Missing | This resource is generally assumed to be active if no value is provided for the active element
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
12. BodyStructure.morphology
Definition | The kind of structure being represented by the body structure at `BodyStructure.location`. This can define both normal and abnormal morphologies.
Control | 0..1
Binding | For example codes, see SNOMEDCTMorphologicAbnormalities Codes describing anatomic morphology.
Type | CodeableConcept
Comments | The minimum cardinality of 0 supports the use case of specifying a location without defining a morphology.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
13. BodyStructure.location
Definition | The anatomical location or region of the specimen, lesion, or body structure.
Control | 1..1
Binding | The codes SHOULD be taken from Precoordinated Body Structures Precoordinated body sites such as 'left ear'
Type | CodeableConcept
Must Support | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
14. BodyStructure.locationQualifier
Definition | Qualifier to refine the anatomical location. These include qualifiers for laterality, relative location, directionality, number, and plane.
Control | 0..*
Binding | For example codes, see BodystructureLocationQualifier Concepts modifying the anatomic location.
Type | CodeableConcept
Must Support | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
