Feature #402

Updated by Alexander Watzinger almost 5 years ago

Idea: It will sometimes be necessary to record a timespan in which the beginning/birth (or death or whatever event) took place.
Example: Person A was born somewhen between the 1st of May 2003 and November 2014.
Possible Solution: Link person A via OA1a (born at) with 2 time primitives. The earlier one is logically the "from" and the other one the "to" value.

*To do*
- update (delete old ones)
implent end
- implement born, died
- implement for relationship
- test invalid date
- check begin not after end
- show in list?

- update date types wiki
- get entity by name: always take first one
