-Once a device message is transformed into a normalized data model, the data is collected for transformation to a [FHIR Observation](https://www.hl7.org/fhir/observation.html). If the Observation type is [SampledData](https://www.hl7.org/fhir/datatypes.html#SampledData), the data is grouped according to device identifier, measurement type, and time period (time period can be either 1 hour or 24 hours). The output of this grouping is sent for conversion into a single [FHIR Observation](https://www.hl7.org/fhir/observation.html) that represents the time period for that data type. For other Observation types ([Quantity](https://www.hl7.org/fhir/datatypes.html#Quantity), [CodeableConcept](https://www.hl7.org/fhir/datatypes.html#CodeableConcept) and [string](https://www.hl7.org/fhir/datatypes.html#string)) data is no grouped, but instead each measurement is transformed into a single Observation representing a point in time.
