Implications and caveats

Severity: Warning

The identificationDate can be earlier than the eventDate if the organism is observed or collected multiple times, e.g. a ringed bird, the same tree that is observed or collected from multiple times, or a living plant from a known accession.

In many data sets, however, it is almost always an error.
