Data Type Profile: PQ - Detailed Descriptions

Draft as of 2024-10-01

Definitions for the PQ data type profile.

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

0. Element
Definition

Elements of this data type are physical quantities, i.e. a measurable quantity (or countable) value from the physical world. This is different from just a “number”, because there is a (natural) unit specified in which the measurable quantity is expressed.

ShortPhysical, measurable quantity with unit

2. Element.id
Definition

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

ShortUnique id for inter-element referencing
Control0..1
This element is affected by the following invariants: ele-1
Typestring
Is Modifierfalse
XML FormatIn the XML format, this property is represented as an attribute.
Summaryfalse
4. Element.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 managable, 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.

ShortAdditional 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.

SlicingThis element introduces a set of slices on Element.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators:
