Mathew and Anders..
I agree with Mathew.
If you take a simple example, one has to identify same thing as same. Only experience teaches that.
An apple is an apple. When you say apple, you need to mean that it is an apple and when you purchase an apple, you should get an apple and not an orange.
But if you need a green apple, you have to say a green apple. If you just say just apple, you may get a red or green apple or you may be asked a question -Do you mean red or green apple?
In complex world, identifying what is same and what is different requires a lot of experience.
In Dr. Sowa's example they had three parts to gender. Male, Female and Mule. Mule and Gender are not the same thing. Mule is an animal that has a gender. They needed to group at a
higher level. People and Machines and Animals ( or mule if that was only animal they were using) at the same level. Then provide gender as an attribute for People and Animals or just for people. Unless animal's gender made difference or needed to be taken for consideration somewhere.
Same things are same, difference things are different. Only experience teaches that. One can not make an orange and apple, even if they paint it red. Because orange still taste different than apple.
Other than things, how same terminologies can have varying descriptions depending on locations and divisions etc that causes problems. So agreeing on same desciption and documenting them with same description helps.

Dear Matthew,
Ah, i was referring to the smale scale temporal ordering in the sentence "first identify what is the same/different, then apply the above.".
Identity is important but why is there a temporal ordering between the two? could you elaborate on the rationale?

In my book “Developing High Quality Data Models” I identify a number of these. But that just means that these are different things, not the same.
