This element intends to bundle all of the various ways of denoting time or age in phenopackets schema. Starting with version 2, other elements will be required to use a TimeElement rather than any of the more specific elements. For instance, the version 1.0 of PhenotypicFeature uses an OntologyClass for the age of onset of the phenotypic feature. Version 2 will replace this with a TimeElement. This will mean that all references to time and age throughout the phenopacket standard are uniform. That this change was needed became obvious when trying to model an acute phenotypic abnormality such as an episode of fever occurring one day before admission to the hospital.
|gestational_age||GestationalAge||(one of the options)||measure of the age of a pregnancy|
|age||Age||(one of the options)||represents age as a ISO8601 duration (e.g., P40Y10M05D).|
|age_range||AgeRange||(one of the options)||indicates that the individual’s age lies within a given range|
|ontology_class||OntologyClass||(one of the options)||indicates the age of the individual as an ontology class|
|timestamp||Timestamp||(one of the options)||indicates a specific time|
|interval||TimeInterval||(one of the options)||indicates an interval of time|
The following shows a TimeElement with the Age option.
timeElement: age: iso8601duration: "P25Y"
A measure of the age of a pregnancy. Gestation, defined as the time between conception and birth, is measured in weeks and days from the first day of the last menstrual period. See GestationalAge.
This element can be used indicates that the individual’s age lies within a given range, which may be desirable to help preserve privacy. See AgeRange
A Timestamp can be used to represent a specific time. Note that all timestamps in a phenopacket can be shifted by the same amount to help preserve privacy if desired.
