Hi Gregor,
I disagree mostly with you in the question of using strings or items for persons, but incidentally, that does not matter. I agree with you fully in the following point:
2012/8/14 Gregor Hagedorn g.m.hagedorn@gmail.com:
I would prefer if the decision whether entity-identity is known or whether only a name-string or other label is known, should be left to the Wikidata editor community, and not prescribed by the software.
I fully agree with that. All I meant is that I would expect that editors will create items for persons, and not use strings. There is indeed nothing in the software to force them to do so.
So, yes, it is up to the community on how to do that.
Cheers, Denny
