Definitions for the LogicalExample logical model

Guidance on how to interpret the contents of this table can be foundhere

0. LogicalExample
Definition

Example Logical Structure Definition Instance

ShortExample Logical Structure Definition
Control0..*
Is Modifierfalse
Logical ModelInstances of this logical model are not marked to be the target of a Reference
2. LogicalExample.foo
Definition

A data element

ShortSome element
Control0..1
Typestring
Primitive ValueThis primitive element may be present, or absent, or replaced by an extension
Invariantsele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. LogicalExample.foo.id
Definition

unique id for the element within a resource (for internal references)


Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Shortxml:id (or equivalent in JSON)Unique id for inter-element referencing
Control0..1
Typestring
Is Modifierfalse
XML FormatIn the XML format, this property is represented as an attribute.
Summaryfalse
6. LogicalExample.foo.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.

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.
