Definitions for the extension-quantity-translation extension.
Guidance on how to interpret the contents of this table can be found here
0. Extension | |
Definition | An alternative representation of the same physical quantity expressed in a different unit from a different unit code system and possibly with a different value. |
Short | Same quantity with different units |
Comments | It is not necessary for information processing entities to check and enforce that the translations are valid translations of the base unit, but they are allowed to do so, and to reject instances where the translations are not valid. NOTE Translations are allowed to contain other representations in UCUM units, but there is generally no point to this as it is possible to convert from one UCUM form to another. |

0. Extension | |
Definition | An alternative representation of the same physical quantity expressed in a different unit from a different unit code system and possibly with a different value. Optional Extension Element - found in all resources. |
Short | Same quantity with different unitsOptional Extensions Element |
Comments | It is not necessary for information processing entities to check and enforce that the translations are valid translations of the base unit, but they are allowed to do so, and to reject instances where the translations are not valid. NOTE Translations are allowed to contain other representations in UCUM units, but there is generally no point to this as it is possible to convert from one UCUM form to another. |
Control | 0..* |
Is Modifier | false |
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()) |
2. Extension.extension | |
Definition | An Extension 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 | ExtensionAdditional 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. |

Slicing | This element introduces a set of slices on Extension.extension . The slices areUnordered and Open, and can be differentiated using the following discriminators: |
4. Extension.url | |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Short | identifies the meaning of the extension |
Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
