| metric | cadf:Metric | Dependent | The property describes the metric used in generating the measurement result. Required if not metricId |
| metricId | cadf:Identifier | Dependent | This property identifies a CADF Metric by reference and whose definition exists elsewhere. Required if not metric |
| calculatedBy | cadf:Resource | No | An optional description of the resource that calculated the measurement |
