Definitions for the Ratio-uv-ips data type profile
Guidance on how to interpret the contents of this table can be foundhere
| 0. Ratio | |
| Definition | A relationship of two Quantity values - expressed as a numerator and a denominator. |
| Short | A 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. |
| Control | 0..* |
| Is Modifier | false |
| Invariants | ele-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.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists()))ele-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.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists())) |

If both are absent, there SHALL be some extension present ( (numerator.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists())) |
| 2. Ratio.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 This element is affected by the following invariants: ele-1 |
| Type | id |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Ratio.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. |
| 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 Ratio.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators: |
| 6. Ratio.numerator | |
| Definition | The value of the numerator. |
| Short | Numerator value |
| Control | 0..1 This element is affected by the following invariants: rat-1 |
| Type | Quantity |
| Is Modifier | false |
| Summary | true |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 8. Ratio.denominator | |
| Definition | The value of the denominator. |
| Short | Denominator value |
| Control | 0..1 This element is affected by the following invariants: rat-1 |
| Type | Quantity(SimpleQuantity) |
| Is Modifier | false |
| Summary | true |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
