In the 55th joint meeting of the CIDOC CRM and SO/TC46/SC4/WG9; 48th FRBR/LRMoo SIG meeting, the SIG resolved to start an issue where to discus the inheritance in strong/weak shortcuts.
P32 used general technique IsA P125, which itself stands as a shortcut for E7. P16: E70. P2: E55. There is no registered instance of a technique over which this is shortcutting. Is the subproperty still valid if there is no instance of technique?
HW: For MD, WS, CEO and TV to fully flesh out.

Dear all
This is interesting.
E7 Activity. P32 used general technique (was technique of): E55 Type
is declared to be a subproperty of
E7 Activity. P125 used object of type (was type of object used in): E55 Type
The object in the label is somewhat misleading.
"This property is a strong shortcut of the more fully developed path from E7 Activity through P16 used specific object, E70 Thing, P2 has type, to E55 Type"
So the object can be anything enduring of cause also a symbolic object which make sense for P32. So for P32 on may consider to replace P16 with a subproperty, say
E7 Activity. P33 used specific technique (was used by): E29 Design or Procedure
Does this give meaning? Opinions?
Best,
Christian-Emil

Dear Christian-Emil,
Indeed, I think this needs discussion. I'd rather think P125 is not superproperty, but P32 is subproperty of P2 has type.
Producing, e.g., a Benin bronze object with lost vax technique, or a traditional Greek window grid by forging and piercing iron rods, has no
specific intermediate. Isn't it?
Best,
Martin
In the 57th CIDOC CRM & 50th FRBR/LRMoo SIG Meeting, CEO suggested that P32 used general technique [D: E7 Activity, R: E55 Type] might be a shortcut over a fully developed path that goes through P33 used specific technique [D: E7 Activity, R: E29 Design or Procedure] and P2 has type.
MD countered that proposal with an alternative, i.e.:
- make P32 used general technique [D: E7 Activity, R: E55 Type] IsA P2 has type [D: E1 CRM Entity, R: E55 Type], and
- disengage P32 from P125 altogether (to be dealt with in a new issue). The general technique may not imply any used object -despite the fact that the full path for P125 goes through P16 used specific object: E70 Thing (so any endurant really).
Decision:
Start a new issue about disengaging P32 from P125 (see 657)
Nb. The decision does not resolve the original question of there being no registered instance of a technique over which P32 is shortcutting
