Clarify documentation of start and end in TSV spec

[frederik-elwert]

The documentation of start currently reads:

Earliest relevant date in ISO 8601 form (YYYY-MM-DD); …

For me, “relevant date” seems to be a bit vague. E.g., does this date refer to the use of the name given, or to the existence/use of the place? Of course the TSV is less expressive than the JSON-LD format, but it would be helpful to understand how a date given here is interpreted during import.

Good point, thanks. I've updated the spec. How does it read now?

Yes, that’s very helpful! (Sorry for the late feedback, somehow the notification got lost.)
