[edit]

@Jakec, tomT0m, GZWDer, Micru: when available, can we use this item for the work where the fact was proved rather than the proving person/organization ? Normally, the provers should be the work's authors. For Pythagoras' theorem, I do not know exactly what should be done, as we do not have any work by Pythagoras. Perhaps just "proved by Pythagoras", perhaps, somehow also add the first known work that proved the theorem ? -Zolo (talk) 09:24, 17 September 2014 (UTC)[reply]

I think the first known document that proved the theorem is a good idea, it's very similar to the taxon description in taxonomy, maybe we should reuse the property. To the Pythagora's theorem, I guess we should rely on sources :) There is also the named after property which can make the link.
By the way, if a theorem have different name in different languages, should not the named after property only be a qualifier of the name ? TomT0m (talk) 10:40, 17 September 2014 (UTC)[reply]
I think "named after" should be used in conjunction with a name string whenever possible. That could be the name as a qualifier of the property rather than the other way round, but it seems less intuitive. So I'd say "named after" always as a qualifier, even though that makes "named afters" harder to query. But I do not think we have any property for names like "Pythagoras' theorem" yet.
What do you mean with reusing taxon description ? --Zolo (talk) 12:05, 17 September 2014 (UTC)[reply]
I thought there was a property corresponding to first valid description (Q1361864)  View with Reasonator View with SQID that linked a species to a document or article that first described the species. I can't find it though, I don't know how they model this. But a property linking any type of scientific concept to the paper that first described it may be a good idea anyway.
