Hoi,

What I mean and what I say is that there has been noone willing to explain why certain items are in there. When you ask questions it is seen as a threat and consequently I find I am treated like one. The consequence is that I do not care about the structure and totally ignore it. This is a shame because on occasion I do expect this has an impact.

Thanks,

GerardM

The subclass of and instance of statements are actually used in very
many WDQS queries, often with * expressions to navigate the hierarchy.

I think that's what Gerard meant: you don't have to know what's under the hood, as long as it works. When you get some unexpected result, you go check what went wrong in the chain of subclasses etc. This is at least what I do, although I also work with some more traditional people who want to know the full ontology before even entering their first statement (of course they get lost for a few months).
