Dear All,
"Thinking of it again", I suggest:
a) The case comparing two instances of E54 Dimension should be a "Data
Evaluation", no more a Measurement.
b) Following the last decisions, we can formulate direct comparative
measurements of two objects or more, such as putting two figurines side
by side and determining the taller, or exact difference in height, etc.
c) I have problems with using O28 generally for E55 Type.
Please think of:
Exx Sortable Type
Tentative Scope Note: "This class comprises concepts, instances of E55
Type, that allow for comparing summarily all particulars they classify
to those classified by some other instances of Exx Sortable Type by some
form of partial or complete order relation, such as "hills" versus
"mountains".
This would require comparable subsets of types.
Or "
This class comprises concepts, instances of E55 Type, that allow for
comparing the particulars they classify by some form of partial or
complete order relation, such as "color intensity".
Or Both?
To be clarified: Where stand mathematical values.
I think an arbitrary order criterion will be ambiguous. Only a question
of phantasy to find them. For instance, compare bird species by medium
size, medium flight speed, medium food consumption, intensity of crying.....
The color IHS space has 3 dimensions.
Where is the order criterion defined???
Best,
Martin

Is this relevant:

It is a draft property in CRMsci:
"O28 is conceptually greater than (is conceptually less than)"
All the best,

To add: Thinking of it again, the Measurement and Dimension classes
cannot be used for cases as the example I provided in my previous
email (since 'E54 Dimension' comprises quantifiable properties that
can be measured by some calibrated means and can be approximated by
values).
Nevertheless, there are cases where the intensity of the earthquake
is given as a number in the original source, e.g. "8", "7-9" or
"probably 8".

Dear all,
First, apologies if my question has already been discussed in a
previous SIG meeting/issue.
I was wondering if CIDOC CRM currently allows representing a
measurement (instance of E16 Measurement), not by providing a value
and unit (through an instance of E54 Dimension), but by comparing it
with an instance of another dimension/measurement.
Use case: modeling information about historical earthquakes.
There are (historical) documents that provide information about
old/ancient earthquakes and this information is expressed at various
levels of detail and precision. For example, there is the below
case:
- Earthquake instance 1: November 26, 1861 (00:40-02:40). Very
strong.
- Earthquake instance 2: November 27, 1861 (04:00-07:00). _Stronger
than that of Nov 6_ (i.e. stronger than earthquake instance 1)
If we ask for "very strong" earthquakes, the ideal system should
also return instance 2.
So, the question is how we can model the information 'stronger than'
between two instances of E54 Dimension (or E60 Number?), since this
is how it appears in the original source.
Is there a straightforward way that I do not see?
Could this be done through E13 Attribute Assignment (if yes, how?)
Thank you!
Best regards,
Pavlos
