From a modelling perspective there are many data points that only make logical sense to be modelled as an Interval event, for example a travel record which should theoretically have a start and end date (date of departure and date of return. Sometimes the end date has not been completed if they are still travelling. Sometimes we need to record where they travelled to, but don’t have dates to set the interval.
I’m sure not having all relevant dates for OBS data IRL is a relatively common occurrence.
How do implementers manage this in practice? What are your tips, thinking, workarounds, for this scenario?
