Hoi, It is in the logic. When a king is a monarch and a monarch is a politician I am fine. But when people insist that a "King of Iberia" is a subclass it does not make sense. People hold the office of and it is singular. When such things result in struggles, I think we have a problem.
I have asked in the past to explain the nonsense on items like monarch. When I look at Reasonator there is so much that is plain problematic that it is best to ignore it. What complicates it is that the ontology seems to end with politician and that is a travesty in and of itself. With other "occupations" there is a wealth of upper levels that seem to be completely arbitrary and when asked I find it reasonable that nobody steps up to explain because the consequences of answers are problematic. Thanks, GerardM

Gerard, I am willing to help. What do you want explained? (We can perhaps move that off-list.)

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).
