Dear All,
I remember a discussion about the quantifiers of P140, P141, assigns
attribute...
As it stands now, they are both
"many to many (0,n:0,n)".
P177 assigned property of type, has
"many to many, necessary (1,n:0,n)"
Firstly, all must be necessary. you cannot assign a property type
without a domain and range.
Secondly, the scope notes of all these properties do use singular, "the":
"This property associates an instance of E13 Attribute Assignment with
the type of property or relation that this assignment maintains to hold
between *the item* to which it assigns an attribute and *the attribute*
itself"
Thirdly, multiple values confuse which is which.
I remember a discussion that, theoretically, if you have:
a) one domain, one type, many ranges
b) many domains, one type, one range
c) one domain, many types, one range,
The propositions are well defined. I assume that this discussion was
never ended, nor such constraints be formulated in Logic. I doubt it can
be in FOL, and is, for any user, utterly *confusing*.
The quantifiers must be: "many to one, necessary (1,1:0,n)"
Generalizing single property assigments for *ISSUE 602*, this *must *be
resolved.
best,
Martin
