Re: [ontolog-forum] What is the role of an upper level ontology?

["Matthew West" <dr.matthew.west@xxxxxxxxx>]

Dear Hassan,

This is conflating two things:

a)      Membership of a club to a sports federation, and of a player to a sports club

b)      Whole-part.

I would argue that it is the membership relation that is not transitive, but that it is quite reasonable to create a mereological sum of the players of the clubs that are members of a sports club and of a sports federation, and that this is transitive.

 

Regards

Could you provide example of a nontransitive part relation

A sport team is part of a sport club. A club is part of a sport federation if it has at least one team all of whose members are professional players. So a sport team may be part of a club, but not part of a federation.
