Dear Christian-Emil,
I agree with all you write. The quantification should be (1,1:0,n) for
all subproperties you have listed.

Martin

Dear Martin,
I have read this issue a little late. I have no problem with your
argumentation. There may be a side effect.
P35:
Quantification: many to many, necessary (1,n:0,n)
For all x,y we have P37(x,y) ⇒P141(x,y)
Since the quantification of P35 is (1,n:0,n), then it may exist
P37(a,b) and P37(a,c) and b is not c. (if not the quantification
should be (1,1:0,n). From the subproperty definition
P37(a,b) ⇒ P141(a,b) and P37(a,c) ⇒ P141(a,c)
so we can conclude that P141(a,b) and P141(a,c) which contradicts the
proposed quantification (1,1:0,n) of P141. In general a subproperty
cannot have a less restrictive quantification than its superproperty.
If I am correct we have check the scopenotes of
P34, P35, P37, P38, P40, P42
P140 assigned attribute to (was attributed by)
Domain: E13Attribute Assignment Range:E1CRM Entity
Superproperty of:
E14 Condition Assessment. P34 concerned (was assessed by): E18Physical
Thing [ (1,n:0,n), not OK]
E16 Measurement. P39 measured (was measured by): E18Physical Thing [OK]
E17 Type Assignment. P41 classified (was classified by): E1 CRM Entity
[OK]
P141 assigned (was assigned by)
Domain: E13Attribute Assignment
Range:E1CRM Entity
Superproperty of:
E14 Condition Assessment. P35 has identified (identified by): Ε3
Condition State [ (1,n:0,n), not OK]
E15 Identifier Assignment. P37 assigned (was assigned by): E42
Identifier [ (0,n:0,n), not OK]
E15 Identifier Assignment. P38 deassigned (was deassigned by): E42
Identifier [ (0,n:0,n), not OK]
E16 Measurement. P40 observed dimension (was observed in):
E54Dimension [ (1,n:0,n), not OK]
E17 Type Assignment. P42 assigned (was assigned by): E55 Type [
(1,n:0,n), not OK]
In all the scopepnotes (P34, P35, P37, P38, P40, P42 ) the instance of
the range is in singular number. So the quantifications can be
adjusted without problem.
Best,
Christian-Emil

*Subject:* [Crm-sig] New ISSUE: Quantifiers of P140,P141,P177
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
