Dear all,
At the last session of the last CRM SIG meeting we discussed issue 511
and voted to accept the reduction of the range of property P39 measured
from E1 CRM Entity to E18 Physical Thing. Homework was assigned to check
how scope notes and related properties are affected, recommend changes
and call an e-vote for those. I am listing the required changes below.
With regards to those changes, the possible votes are:
* Yes = accept/agree
* No = do not accept/agree
* Other = With other you can either introduce a caveat (e.g.: 'Yes,
but there is a typo on word x, fix it.') or you can write VETO, if
you wish to stop the proposed change from happening, in which case
you should also write a justification and reformulate the issue
(e.g.: 'VETO, this change is unacceptable because it violates the
following principle...')

*1. E16 Measurement*
Changed to clarify that E16 Measurement requires observation, including
an update to an example and the removal of two examples.
*From:*
Subclass of:
E13 <#_toc7577> Attribute Assignment
Scope note:
This class comprises actions measuring quantitative physical properties
and other values that can be determined by a systematic, objective
procedure of direct observation of particular states of physical
reality. Properties of instances of E90 Symbolic Object may be measured
by observing some of their representative carriers which may or may not
be named explicitly. In the case that the carrier can be named, the
property P16 used specific object (was used for): should be used to
indicate the instance(s) of E18 Physical Thing that was used as the
empirical basis for the measurement activity.
Examples include measuring the nominal monetary value of a collection of
coins or the running time of a movie on a specific video cassette.
The E16 Measurement may use simple counting or tools, such as yardsticks
or radiation detection devices. The interest is in the method and care
applied, so that the reliability of the result may be judged at a later
stage, or research continued on the associated documents. The date of
the event is important for dimensions, which may change value over time,
such as the length of an object subject to shrinkage. Methods and
devices employed should be associated with instances of E16 Measurement
by properties such as P33 used specific technique: E29 Design or
Procedure, P125 used object of type: E55 Type, P16 used specific object
(was used for): E70 Thing, whereas basic techniques such as "carbon 14
dating" should be encoded using P2 has type (is type of): E55 Type.
Details of methods and devices reused or reusable in other instances of
E16 Measurement should be documented for these entities rather than the
measurements themselves, whereas details of particular execution may be
documented by free text or by instantiating adequate sub-activities, if
the detail may be of interest for an overarching query.
Regardless whether a measurement is made by an instrument or by human
senses, it represents the initial transition from physical reality to
information without any other documented information object in between
within the reasoning chain that would represent the result of the
interaction of the observer or device with reality. Therefore, inferring
properties of depicted items using image material, such as satellite
images, is not regarded as an instance of E16 Measurement, but as a
subsequent instance of E13 Attribute Assignment. Rather, only the
production of the images, understood as arrays of radiation intensities,
is regarded as an instance of E16 Measurement. The same reasoning holds
for other sensor data.
Examples:
* measurement of height of silver cup 232 on the 31st August 1997
(fictitious)
* the carbon 14 dating of the “Schoeninger Speer II” in 1996 [an about
400.000 year old complete Old Palaeolithic wooden spear found in
Schoeningen, Niedersachsen, Germany in 1995] (Kouwenhoven, 1997)
* The pixel size of the jpeg version of Titian’s painting Bacchus and
Ariadne from 1520–3, as freely downloadable from the National
Gallery in London’s web page
<https://www.nationalgallery.org.uk/paintings/titian-bacchus-and-ariadne>
is 581600 pixels.
* The scope note of E21 Person in the Definition of the CIDOC
Conceptual Reference Model Version 5.0.4 as downloaded from
<http://www.cidoc-crm.org/sites/default/files/cidoc_crm_version_5.0.4.pdf>

*2.**P39 measured (was measured by)*
Changed to reduce the range to E18, update the scope note and the second
example.
*From:*
*
*
Domain:
E16 <#_toc7618> Measurement
Range:
E1 <#_toc7281> CRM Entity
Subproperty of:
E13 <#_toc7561> Attribute Assignment. P140 <#_toc11015> assigned
attribute to (was attributed by): E1 <#_toc7281> CRM Entity
Quantification:
many to one, necessary (1,1:0,n)
Scope note:
This property associates an instance of E16 Measurement with the
instance of E1 CRM Entity to which it applied. An instance of E1 CRM
Entity may be measured more than once. Material and immaterial things
and processes may be measured, e.g., the number of words in a text, or
the duration of an event.
Examples:
* 31 August 1997 measurement of height of silver cup 232 (E16)
/measured/ silver cup 232 (E22) (fictitious)
In First Order Logic:
P39(x,y) ⇒ E16(x)
P39(x,y) ⇒ E1(y)
P39(x,y) ⇒ P140(x,y)
*To:*

E16 <#_toc7618> Measurement
Range:
E18 <#_toc7281> Physical Thing
Subproperty of:
E13 <#_toc7561> Attribute Assignment. P140 <#_toc11015> assigned

Scope note:
This property associates an instance of E16 Measurement with the
instance of E18 Physical Thing upon which it acted. The instance of E16
Measurement is specific to the measured object. An instance of E18
Physical Thing may be measured more than once with different results,
constituting different instances of E16 Measurement.
Examples:
* 31 August 1997 measurement of height of silver cup 232 (E16)
/measured/ silver cup 232 (E22) (fictitious)
* the carbon 14 dating of the “Schoeninger Speer II” in 1996 (E16)
/measured/ the “Schoeninger Speer II” (E22) [The carbon 14 dating of
an approximately 400.000 year old complete Old Palaeolithic wooden
spear found in Schoeningen, Niedersachsen, Germany in 1995. See also
E16 Measurement] (Kouwenhoven, 1997)

P39(x,y) ⇒ E18(y)
P39(x,y) ⇒ P140(x,y)
*3.**P140 assigned attribute to (was attributed by)*
Only updated the reference P39 measured as a sub-property of P140.
*From:*
Superproperty of:

*4. P40 observed dimension (was observed in)*
Added a second example:
* the carbon 14 dating of the “Schoeninger Speer II” in 1996 (E16)
/observed dimension/ the carbon 14 based temporal distance from 1996
to the growth of the wood of the “Schoeninger Speer II” [The carbon
14 dating of an approximately 400.000 year old complete Old
Palaeolithic wooden spear found in Schoeningen, Niedersachsen,
Germany in 1995. See also E16 Measurement] (Kouwenhoven, 1997)
*5. **P43 has dimension (is dimension of)*
*
*
Modified scope note to indicate that the long path through /P39i was
measured/ by applies to /E18 Physical Thing/ and not /E70 Thing/ (note
that this change does not affect the domain of P43).
*From:*
Domain:
E70 <#_toc8408> Thing
Range:
E54 <#_toc8128> Dimension
Quantification:
one to many, dependent (0,n:1,1)
Scope note:
This property records a E54 Dimension of some E70 Thing.
This property is a shortcut of the more fully developed path from E70
Thing through /P39i was measured by/, E16 Measurement, /P40 observed
dimension/, to E54 Dimension. It offers no information about how and
when an E54 Dimension was established, nor by whom.
An instance of E54 Dimension is specific to an instance of E70 Thing.
Examples:
* silver cup 232 (E22) /has dimension/ height of silver cup 232 (E54)
/has unit/ (P91) mm (E58), /has value/ (P90) 224 (E60) (fictitious)
In First Order Logic:
P43(x,y) ⇒ E70(x)
P43(x,y) ⇒ E54(y)
P43(x,y) ⇐ (∃z) [E16(z) ˄ P39i(x,z) ˄ P40(z,y)]
*To:*
Domain:
E70 <#_heading=h.4anzqyu> Thing
Range:
E54 <#_heading=h.40ew0vw> Dimension
Quantification:
one to many, dependent (0,n:1,1)
Scope note:
This property records a E54 Dimension of some E70 Thing.
It offers no information about how and when an instance of E54 Dimension
was established, nor by whom. In the case that the recorded property is
a result of a measurement of an instance of E18 Physical Thing, this
property is a shortcut of the more fully developed path from E18
Physical Thing through /P39i was measured by/, E16 Measurement, /P40
observed dimension/, to E54 Dimension. It offers no information about
how and when an E54 Dimension was established, nor by whom. Knowledge
about an instance of E54 Dimension need not be result of a measurement;
it may be the result of evaluating data or other information, which
should be documented as an instance of E13 Attribute Assignment.
An instance of E54 Dimension is specific to an instance of E70 Thing.
Examples:
* silver cup 232 (E22) /has dimension/ height of silver cup 232 (E54)
/has unit/ (P91) mm (E58), /has value/ (P90) 224 (E60) (fictitious)
In First Order Logic:
P43(x,y) ⇒ E70(x)
P43(x,y) ⇒ E54(y)
P43(x,y) ⇐ (∃z) [E16(z) ˄ P39i(x,z) ˄ P40(z,y)]
Please send your e-votes by the 26th of March.
All the best,
Thanasis
