Dear all,
In issue 388
(https://cidoc-crm.org/Issue/ID-388-reference-to-the-measurements-of-position-of-things)
we agreed the properties for position measurement. This issue 611
(https://cidoc-crm.org/Issue/ID-611-scope-notes-for-the-properties-of-position-measurement)
is about creating their scope notes and examples. Athina, Gerald, Martin
and I have drafted these as shown below. Please consider them and we can
discuss at the next SIG meeting. The examples for S23 at the bottom are
included to correspond with the ones for the properties.
All the best,
Thanasis
O30determined position (was determined by)
Domain:
S23 Position Measurement
Range:
E94 Space Primitive
Subproperty of:
S4 Observation: O16 observed value (value was observed by): E1 CRM Entity
Quantification:
many to many (0,n:0,n)
Scope note:
This property associates an instance of S23 Position Measurement with
the instance of E94 Space Primitive which is the result of
thatmeasurement. The instance of E94 Space Primitive approximates the
place occupied by the entity whose position is being measured.
Examples:
*
The measurement of the position of the Titanic by captain Smith
after hitting an iceberg (S23) O30 determined position41°44′N
50°24′W (E94) [This was quickly measured based on the distance
travelled since the previous known location] (Tikkanen, 2022)
*
The measurement of the position of the Titanic by officer Joseph G.
Boxhall after the initial distress signal was sent (S23) O30
determined position41°46′N 50°14′W (E94) [This was measured with
more precision and revised the original position] (Tikkanen, 2022)
*
The measurement of the position of the Titanic by Robert Ballard
after the Titanic ship-wreck was found (S23) O30 determined
position41°43′32″N 49°56′49″W (E94) (‘Wreck of the Titanic’,
Wikipedia, 2022)
In First Order Logic:
Oxx1(x,y) ⇒ S23(x)
Oxx1(x,y) ⇒ E94(y)
O31has validity time-span(is time-span validity for)
Domain:
S23 Position Measurement
Range:
E52Time-Span
Subproperty of:
E2 Temporal Entity: P4 has time-span (is time-span of): E52 Time-Span
Quantification:
many to one, necessary (1,1:0,n)
Scope note:
This property associates an instance of S23 Position Measurement with
the instance of E53 Time-Span for which the measurement is valid. No
inferences can be made in relation to the validity of the measurement
outside this time-span despite the fact that some measured entities are
relatively stable and their positions may remain the same after the
measurement. The time-span of validity should fall within (P86 falls
within (contains)) the overall time-span (P4 has time-span (is time-span
of) of the process of measurement.
Examples:
*
The measurement of the position of the Titanic by captain Smith
after hitting an iceberg (S23) O31 has validity time-spanfrom 15
April 1912 00:15 to 15 April 1912 00:20 (E52) [This was only valid
while the position was being re-measured] (Tikkanen, 2022)
*
The measurement of the position of the Titanic by officer Joseph G.
Boxhall after the initial distress signal was sent (S23) O31 has
validity time-spanfrom 15 April 1912 00:20 to 15 April 1912 02:17
(E52) [This was valid after the position was re-measured with more
precision and was the measured position of the ship until the final
distress signal was sent] (Tikkanen, 2022)
*
The measurement of the position of the Titanic by Robert Ballard
after the Titanic ship-wreck was found (S23) O31 has validity

In First Order Logic:
Oxx2(x,y) ⇒ S23(x)
Oxx2(x,y) ⇒ E52(y)
Oxx2(x,y) ⇒ P4(x,z) ) ∧ P86(y,z)
O32measuredposition of (was locatedby)
Domain:
S23 Position Measurement
Range:
S15 Observable Entity
Subproperty of:
S4Observation: O8observed (was observed by): S15Observable Entity
Quantification:
many to one, necessary (1,1:0,n)
Scope note:
This property connects an instance of S23 Position Measurement with the
instance of S15 Observable Entity whose position is being measured.
Examples:
*
The measurement of the position of the Titanic by captain Smith
after hitting an iceberg (S23) O32 measured position ofthe Titanic
(E22) (Tikkanen, 2022)
*
The measurement of the position of the Titanic by officer Joseph G.
Boxhall after the initial distress signal was sent (S23) O32
measured position ofthe Titanic (E22) (Tikkanen, 2022)
*
The measurement of the position of the Titanic by Robert Ballard
after the Titanic ship-wreck was found (S23) O32 measured position
ofthe Titanic (E22) (‘Wreck of the Titanic’, Wikipedia, 2022)
In First Order Logic:
Oxx3(x,y) ⇒ S23(x)
Oxx3(x,y) ⇒ S15(y)
