indeed. We already have period data type, a year data type would make sense.

And more generally, why don't we show the date if it is a date?

@BrendaHijmans if we use date then we should show the date? or should we revert to year?

The issue linked to this PR was closed after this comment:
"Why are we changing a date that is filled out into year? We made a deliberate choice to include start and end date into the collection events and end year/start year for resources. Data collection period may be more precisely recorded than the start/end of a resource."
