Tests are a bit depressing. - "Borane" has two unlinked entries: Q127611 is "any chemical compound composed of boron and hydrogen atoms only" while Q15634214 is specifically boron trihydride. Both correct, but the latter should be labelled as an instance of the former. - "Anomalocaris" has Q37395 for the "extinct genus of radiodon" (instance of "fossil taxon") but species (e.g. Q49557506 Anomalocaris cranbrookensis) do not link to it. - There are no lists of links, for example Q936518 ("aerospace manufacturer") doesn't have a list of its instances (e.g. Boeing, Q66, or Arado Flugzeugwerke, Q624899).

> There are no lists of links, for example Q936518 ("aerospace manufacturer") doesn't have a list of its instances (e.g. Boeing, Q66, or Arado Flugzeugwerke, Q624899) This is intentional, you can construct these via the query service. There's also an optional "gadget" registered users can add to their configuration, that can do this automatically when visiting a page for every instance of some "inverse" property.

  I thought this is what the "What links here" link on the left was for? https://www.wikidata.org/wiki/Special:WhatLinksHere/Q936518 https://www.wikidata.org/wiki/Special:WhatLinksHere/Q936518

    Well, "what links here" gives you a general list of related pages without telling you which is relevant to the property you care about. It's sometimes useful (esp. for items with few incoming links), but the query service is a more complete solution.

> Both correct, but the latter should be labelled as an instance of the former. No, it should be labelled as an subclass of the former. Instance would be a specific piece of borane.
