time measurement datum
age measurement datum
A time measurement datum that is the result of measurement of age of an organism
In MageTab file, we use
initialTimePoint (a process) + age (a number expected) + TimeUnit (definied in UO, such as year, hour, day, etc.)
Now we use the term label indicating the start time point of measuring the age, (number + TimeUnit) are expected instances of the class
MO_178 Age

discussed on Nov 15, dev call
All subtype will be defined by textual definition now.
note that we are currently defining subtypes of age measurement datum that specify when the age is relative to, e.g. planting, as we don't have adequate temporal predicates yet.
life of bearer doesn't imply organism
this assay measures time not developmental stage. we recognize that development can take different time periods under different conditions such as media / temperature
age as a quality is dubious; we plan to revisit
stages in development are currently handled with controlled vocabulary, such as 2-somite stage
