I thought you meant that these were truly useless items, like someone typing in "hello world", hitting "Save" and then moving on. (Looking at these items, it looks like a lot of them, while not quite that bad, should be turned into redirects. I randomly clicked on this one, for example: https://www.wikidata.org/wiki/Q12672715 , and it looks like it should be merged in to https://www.wikidata.org/wiki/Q466973 .) With that said, for items that do already correspond to a Wikipedia/Wikimedia page and are thus presumably valid, I don't think having zero properties is in itself a major issue - that is, it's not much worse than having only one property. That's a matter of opinion, of course. You could argue that lacking both "instance of" and "subclass of" makes an item unknowable, but in that case, the set of items that lack both of these properties is the real issue, regardless of what other data they hold. > > ---- > Not so much related to the current discussion, > The items with P31 human settlements without a country: I only included > P31 = human settlement, and not a subclass of human settlements.

Given that you were only going for "human settlement", you did an amazing job. -Yaron -- WikiWorks · MediaWiki Consulting · http://wikiworks.com
