Draft as of 2025-11-18

Definitions for the AziendaSanitaria logical model.

- Key Elements Table
- Differential Elements Table
- Snapshot Elements Table

0. AziendaSanitaria
Definition | Modello Logico che definisce il set minimo di dati che caratterizzano una Azienda Sanitaria Base definition for all elements in a resource.
Short | Azienda SanitariaBase for all elements
Control | 0..* This element is affected by the following invariants: ele-1
Is Modifier | false
Logical Model | Instances of this logical model are not marked to be the target of a Reference
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`) ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
2. AziendaSanitaria.id
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Short | Unique id for inter-element referencing
Control | 0..1
Type | string
Is Modifier | false
XML Format | In the XML format, this property is represented as an attribute.
Summary | false
4. AziendaSanitaria.extension
Definition | 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.
Short | Additional content defined by implementations
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.
Control | 0..*
Type | Extension
Is Modifier | false
Summary | false
Alternate Names | extensions, user content
Invariants | 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())
Slicing | This element introduces a set of slices on `AziendaSanitaria.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
6. AziendaSanitaria.identificativo
Definition | ID Azienda Sanitaria
Short | ID Azienda Sanitaria
Control | 0..*
Type | Identifier(Identifier)
8. AziendaSanitaria.nome
Definition | Nome Azienda
Short | Nome Azienda
Control | 0..*
Type | string(string)
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
