Dear All,
Indeed, I see two characteristic cases:
A) broken surfaces:
This is characteristic for statues, which miss heads or limbs, but also
for architectural elements. The Roman statues without heads have
characteristic places where to place the head. There is the reasoning
that people hardly produced a statue with a broken-off arm in antiquity.
These parts have not been discrete before being broken of. In other
cases, there may be traces of mortar or other cement to the connected
component, or damaged joining features, such as corrupted screw holes etc.
B) If an object is found in a context of /use/, rather than in a
/factory/, we can assume that it contained all essential components.
I agree with Oeyvind that a part removal is not adequate for a
deterioration happening when some objects down etc. Therefore I raised
the issue, because there is no obvious workaround in CRM currently.
The property should be used when there is enough plausibility that the
object was complete. I do not assume someone went to a battle field with
a chariot without wheels. Even if, the cases are so marginal they are
irrelevant for the purpose of the CRM.
See also our paper, in which we analyzed a lot of situations:

Dear Martin,
maybe I misunderstood, but how can we explicitly know thw
circumstances of leading to this state, described by the property?
what I mean is, that this property seems to me related to the
definition of situations and to inference (how can we assert the
validity of missing parts? and what about the FOL? can it support it?
It seems useful but isn't it a kind of inference? just a question or
maybe I am missing something

Dear All,
In the discussion about typed negative properties, I have the
impression that a property:
"misses part of type" may be utterly useful for finding archaeological
object in a global search,
such as the head or arms of a statue, characteristic elements of
buildings etc.
Admittedly, it poses the question where to stop the non-existence, and
what missing parts would have a chance to be found.
Would a part lost by accident be a part removal? Would that be an
alternative way of documenting missing parts?
Opinions?
Best,
Martin
