Dear Oeyvind,
"objective" may be an overkill. I thought of using a yardstick, which
compare the Yardstick with the item by human senses. The method is
objective. Do you have examples of non-objective measurements? The term
"immediate" I would not like to drop, because I want to make clear that
evaluation of documents is not regarded as measurement. "Remote sensing"
still requires the sensors to be in place at the time. Astronomy is not
a priority domain for us, but "measuring" a Supernova at several
thousand light years distance would require measuring a Supernova
signasl arriving at us. So, for me measurement means being in immediate
contact with the measured.
Would that make sense?
Cheers,
Martin

Dear Martin,
I think the following claim is too strong: “a systematic, objective
procedure of immediate observation” I think both objective and
immediate have to be qualified in order to be used in this context. As
the last paragraph describes the process in some detail, the reference
to objectivity and immediateness can also just be removed.
All the best,
Øyvind

Dear All,
After consultation with Achille and Thanasi, here my proposed scope
note for E16. The idea is to introduce S4 Observation and Observable
Entity into CRM proper.
*Old Scope note:*
E16 Measurement
Subclass of:E13 <x-msg://15/#_E13_Attribute_Assignment> Attribute
Assignment
Scope note: This class comprises actions measuring physical
properties and other values that can be determined by a systematic
procedure.
Examples include measuring the monetary value of a collection of
coins or the running time of 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. Details of methods and devices are best handled as free
text, whereas basic techniques such as "carbon 14 dating" should be
encoded using /P2 has type (is type of:) E55 Type/.
Examples:
§measurement of height of silver cup 232 on the 31^st August 1997
§the carbon 14 dating of the “Schoeninger Speer II” in 1996 [an about
400.000 years old Palaeolithic complete wooden spear found in
Schoeningen, Niedersachsen, Germany in 1995]
In First Order Logic:
E16(x) ⊃E13(x)
Properties:
P39 <x-msg://15/#_P39_measured_%28was_measured%20by%29:> measured
(was measured by): E1 <x-msg://15/#_E1_CRM_Entity> CRM Entity
P40 <x-msg://15/#_P40_observed_dimension_%28was%20observe> observed
dimension (was observed in): E54 <x-msg://15/#_E54_Dimension> Dimension
*New Scope Note:*
E16 Measurement
Subclass of:E13 <x-msg://15/#_E13_Attribute_Assignment> 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 immediate observation of
particular states of physical reality. Properties of instances of E90
Symbolic Object may be measured via observing some of their
representative carriers.
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,/ /P125 used object of type/,/P16 used specific object/,
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 subactivities, 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 in 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 instance of E16 Measurement, but
as another form of subsequent attribute assignment. Rather, the
production of the images themselves is regarded as instance of E16
Measurement. The same reasoning holds for other sensor data.
Examples:
§measurement of height of silver cup 232 on the 31^st August 1997
§the carbon 14 dating of the “Schoeninger Speer II” in 1996 [an about
400.000 years old Palaeolithic complete wooden spear found in
Schoeningen, Niedersachsen, Germany in 1995]
In First Order Logic:
E16(x) ⊃E13(x)
Properties:
P39 <x-msg://15/#_P39_measured_%28was_measured%20by%29:> measured
(was measured by): E1 <x-msg://15/#_E1_CRM_Entity> CRM Entity
P40 <x-msg://15/#_P40_observed_dimension_%28was%20observe> observed
dimension (was observed in): E54 <x-msg://15/#_E54_Dimension> Dimension
Best,
Martin
