Dear George,
An instance of a property class represents a statement / formal
proposition. Could we thus say that it is also an E73 Information Object?
Would multiple instantiation provide a solution to the problem you
describe? E.g.:
:painting_sistine_chapel
crm:P14_carried_out_by :Michelangelo .
*:statement1*
a crm:PC14_carried_out_by, *crm:E73_Information_Object* ;
crm:P01_has_domain :painting_sistine_chapel ;
crm:P02_has_range :Michelangelo ;
crm:P14.1_in_the_role_of :master_craftsman .
:attrAssign1
a crm:E13_Attribute_Assignment ;
crm:P140_assigned_attribute_to *:statement1*
... ... ...
Thoughts?
Have a good weekend!
Best,
Pavlos
