[PatC]: One or the other view (3D or 4D) may be convenient for different tasks, and I think ontologists should feel free to use either, knowing that an accurate translation is available when needed, as PatH has said.
[MW>] Yes indeed. I don’t think that is the issue. The issue is whether you can ignore the difference, or whether you need to be aware of which choice you have made and its consequences for what you are doing.
Yes, indeed. One should understand that there is a difference, what the difference is, and how to translate the two views of objects in time. One shouldn’t be building ontologies if one can’t get that clear.
