Hello,

I am hoping you might be able to help me with a small confusion -

The scope note for 
E80_Part_Removal<https://cidoc-crm.org/Entity/e80-part-removal/version-7.1.1> 
states that "This class comprises the activities that result in an instance of 
E18 Physical Thing being decreased by the removal of a part." This reads to me 
as if the relationship would then go: E80 > P112_diminished > E18, as P112 
creates the connection to the thing being diminished (having something removed 
from it), as opposed to P113_removed, which is for the connection to the thing 
that was removed.
However, the range of P112 is E24, not E18, and the scope note for 
P112_diminished<https://cidoc-crm.org/Property/p112-diminished/version-7.1.1> 
reads "This property identifies the instance E24 Physical Human-Made Thing that 
was diminished by an instance of E80 Part Removal."
Meanwhile, the range of 
P113_removed<https://cidoc-crm.org/Property/p113-removed/version-7.1.1> is E18, 
as is the range of P31_has_modified<https://cidoc-crm.org/node/8121>, the 
superproperty of P112.

It seems to me therefore that either I am reading the scope note incorrectly 
(very possible!) or that there is an inconsistency between the two, perhaps in 
the range of P112?

I looked in the Issues history for anything about this, and wonder if the 
discussion around the change of P31 (Issue 
191<https://cidoc-crm.org/Issue/ID-191-range-of-p31>) might have relevance to 
either the range or language around it, as in that case the range of P31 was 
relaxed from E24 to E18. Although, that being said, this perceived E18/E24 
inconsistency as described above exists as far back as 
v4.0<https://cidoc-crm.org/html/cidoc_crm_v4.0.html#E80>, the earliest version 
available on the website, so perhaps it is my reading of the scope note that is 
backwards...

To summarize, my question is - Which is the correct range of P112: E18 as 
stated in the E80 scope note or E24 as stated in the P112 scope note and range; 
or am I reading this set of notes/relationships incorrectly?

Thanks for your guidance on this,
Erin Canning
