Data Type Profile: CHEMEDEPRRatioAmountPerAmount - Detailed Descriptions

Draft as of 2025-01-21

Definitions for the ch-emed-epr-ratio-amount-per-amount data type profile.

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

0. Ratio
Definition

A relationship of two Quantity values - expressed as a numerator and a denominator.

ShortA ratio of two Quantity values - a numerator and a denominator
Comments

The Ratio datatype should only be used to express a relationship of two numbers if the relationship cannot be suitably expressed using a Quantity and a common unit. Where the denominator value is known to be fixed to "1", Quantity should be used instead of Ratio.

This element is affected by the following invariants: ele-1
Is Modifierfalse
Invariantsele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ((numerator.empty() xor denominator.exists()) and (numerator.exists() or extension.exists()))
rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ((numerator.empty() xor denominator.exists()) and (numerator.exists() or extension.exists()))
2. Ratio.id
Definition

Implementers should not set or read this element. This element is only kept as optional to allow submission of documents that would contain a value, since those documents are still readable by others. The meaning of this element is undefined in this profile.


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

4. Ratio.extension
Definition

Implementers should not set or read this element. This element is only kept as optional to allow submission of documents that would contain a value, since those documents are still readable by others. The meaning of this element is undefined in this profile.


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✕ This element is not supportedAdditional 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 Ratio.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators:
  • value @ url
  • 6. Ratio.numerator
