D.4.1.1 Formal Views of Profile Content

The official URL for this profile is: 

http://hl7.org/fhir/uv/cpg/StructureDefinition/cpg-shareablestructuredef

Profile of StructureDefinition to establish minimum expectations for sharing a StructureDefinition including URL, name, and version. This profile also provides the ability to declare knowledge representation level and knowledge artifact capabilities.

This profile builds on StructureDefinition.

This profile was published on Thu Jun 06 00:00:00 UTC 2019 as a draft by Health Level Seven, Inc. - CDS WG.

Constraints

IdPathDetailsRequirements
dom-2StructureDefinitionIf the resource is contained in another resource, it SHALL NOT contain nested Resources
: contained.contained.empty()
dom-3StructureDefinitionIf 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-4StructureDefinitionIf 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-5StructureDefinitionIf a resource is contained in another resource, it SHALL NOT have a security label
: contained.meta.security.empty()
dom-6StructureDefinitionA resource should have narrative for robust management
: text.`div`.exists()
sdf-0StructureDefinitionName should be usable as an identifier for the module by machine processing applications such as code generation
: name.matches('[A-Z]([A-Za-z0-9_]){0,254}')
sdf-1StructureDefinitionElement paths must be unique unless the structure is a constraint
: derivation = 'constraint' or snapshot.element.select(path).isDistinct()
sdf-15aStructureDefinitionIf the first element in a differential has no "." in the path and it's not a logical model, it has no type
: (kind!='logical' and differential.element.first().path.contains('.').not()) implies differential.element.first().type.empty()		No Type on the root element (differential)
sdf-4StructureDefinitionIf the structure is not abstract, then there SHALL be a baseDefinition
: abstract = true or baseDefinition.exists()		Ensure that the base types are abstract
sdf-5StructureDefinitionIf the structure defines an extension then the structure must have context information
: type != 'Extension' or derivation = 'specialization' or (context.exists())
sdf-6StructureDefinitionA structure must have either a differential, or a snapshot (or both)
: snapshot.exists() or differential.exists()
sdf-9StructureDefinitionIn any snapshot or differential, no label, code or requirements on an element without a "." in the path (e.g. the first element)
: children().element.where(path.contains('.').not()).label.empty() and children().element.where(path.contains('.').not()).code.empty() and children().element.where(path.contains('.').not()).requirements.empty()		Because these 3 fields seem to be have overlapping meaning with the ones in the root of StructureDefinition
sdf-11StructureDefinitionIf there's a type, its content must match the path name in the first element of a snapshot
: kind != 'logical' implies snapshot.empty() or snapshot.element.first().path = type		Ensure that the type is not inconsistent with the other information in the structure
sdf-14StructureDefinitionAll element definitions must have an id
: snapshot.element.all(id.exists()) and differential.element.all(id.exists())		elements have id
sdf-15StructureDefinitionThe first element in a snapshot has no type unless model is a logical model.
: kind!='logical' implies snapshot.element.first().type.empty()		No Type on the root element (snapshot)
sdf-16StructureDefinitionAll element definitions must have unique ids (snapshot)
: snapshot.element.all(id.exists()) and snapshot.element.id.trace('ids').isDistinct()		element ids need to be unique
sdf-17StructureDefinitionAll element definitions must have unique ids (diff)
: differential.element.all(id.exists()) and differential.element.id.trace('ids').isDistinct()		element ids need to be unique
sdf-18StructureDefinitionContext Invariants can only be used for extensions
: contextInvariant.exists() implies type = 'Extension'		contextInvariant
sdf-19StructureDefinitionFHIR Specification models only use FHIR defined types
: url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (differential.element.type.code.all(matches('^[a-zA-Z0-9]+$') or matches('^http:\\/\\/hl7\\.org\\/fhirpath\\/System\\.[A-Z][A-Za-z]+$')) and snapshot.element.type.code.all(matches('^[a-zA-Z0-9\\.]+$') or matches('^http:\\/\\/hl7\\.org\\/fhirpath\\/System\\.[A-Z][A-Za-z]+$')))		custom types only in logical models
sdf-21StructureDefinitionDefault values can only be specified on specializations
: differential.element.defaultValue.exists() implies (derivation = 'specialization')		no default values on data types or resources
sdf-22StructureDefinitionFHIR Specification models never have default values
: url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (snapshot.element.defaultValue.empty() and differential.element.defaultValue.empty())		no default values on data types or resources
sdf-23StructureDefinitionNo slice name on root
: (snapshot | differential).element.all(path.contains('.').not() implies sliceName.empty())		no sliceName on root
