'''Solution:''' | '''Solution:''' Many legitimate very old dates exist, however a date of collection or identification before the birth date of the collector or determiner will trigger a data quality notification in Arctos. | ||

'''Problem:''' The date the specimen was identified (dateIdentified field) is earlier than the date the specimen was collected (eventDate). | '''Problem:''' The date the specimen was identified (dateIdentified field) is earlier than the date the specimen was collected (eventDate). | ||
'''Solution:''' | '''Solution:''' Arctos supports more than collecting, so something may legitimately be identified (as in an observation) prior to being collected, however, there is a curatorial report that flags this situation for review. | ||
