Hoi, Amir has created functionality that compares data from en.wp de.wp and it.wp. It is data about "humans" and it only shows differences where they exist. It compares those four Wikipedias with information in Wikidata.
The idea is that the report will be updated regularly.
The problem we face is: what should it actually look like. Should it just splatter the info on a page or is more needed. At this time we just have data [1].
Please help us with something that works easily for now. Once we have something, it can be prettified and more functional. Thanks, GerardM
