Dear Wikidata list,
one of our big contributors, Bruno Belhoste in Paris, just gave me a weird question which I feel I cannot answer that fast.
We, FactGrid, are a Wikidata child and so it came that we adopted structures like the father/mother differentiation. Bruno's question is now whether it would not have been wise to just create just a "parent" option instead of the gender fork that splits the
lineages. Let me insert his mail:

I wonder what people with more data knowledge think about the proposal (which would affect just our site, not Wikidata...) (so: no worries, we can do experimental things without affecting our parent - I hesitate to speak of a father or mother - Wikidata).
Best,
Olaf
