Dear All,
Just to give you a picture of the diversity and complexity we discuss.
Probably the high-end in complexity is a DNA - taxonomic distance
measurement, a procedure, even though straightforward and deterministic,
as I understand, with an great number of steps, a series of instruments
subsequently used and possible errors in each one.
Interesting also a LIPS / Raman analysis of painting colorants, which
uses multiple instruments until the final result, not reliably
quantitative and including assumptions about a limited set of possible
colorants that might be wrong.
As the most simple ones we may have yard sticks, but the most exotic in
simplicity I can think of are pyrometric cones. They are used worldwide
to monitor ceramic firings in industrial kilns, pottery kilns, for a
one-time measurement of the maximum temperature reached by firing a
kiln. They are calibrated to one temperature only, but normally
destroyed by the measurement.
What is "one instrument", and are pyrometric cones and yardsticks
instruments? What about body parts (ells, feet)

I think this would be a useful discussion and class. It has also been
proposed within the PARCOURS model although perhaps a tighter proposal
can be made.

P.S. The example for P103 could do with updating...

Hi George,
I think this is a good idea, of course, we should first look at a
more specific property, since "instruments" can be very
heterogeneous, or we concentrate on measurement devices in a narrower
sense.

Dear all,
I am working on a conservation science modelling project in which
the users document also their machinery. Something that comes up is
that they want to document the kind of property or variable that is
measured by the machine. This is a property of the machine, what it
can do (dunamis).
We of course already have p103 was intended for
http://www.cidoc-crm.org/Property/P103-was-intended-for/version-7.1.1
<http://www.cidoc-crm.org/Property/P103-was-intended-for/version-7.1.1>
I already make use of this for the purpose of documenting the
general kind of method the machine can be used for.
But when you run the machine, it tests for certain variables and
produces a resulting output which is a digital record of a signal
carrying that variable.
This reminds me of some elements from CRMSci and from CRMdig
CRMSci has observations that look for property types:
S4 Observation
O9 observed property type E55
http://www.cidoc-crm.org/crmsci/sites/default/files/CRMsci%20v.1.3.pdf
<http://www.cidoc-crm.org/crmsci/sites/default/files/CRMsci%20v.1.3.pdf>
We also have in CRMdig both a class for instruments (digital ones)
D8 Digital Device
and we again have a notion of an observation kind of event measuing
a kind of thing
D11 Digital Measurement Event
L17 measured thing of type E55
http://www.cidoc-crm.org/crmdig/sites/default/files/CRMdig_v3.2.1.pdf
<http://www.cidoc-crm.org/crmdig/sites/default/files/CRMdig_v3.2.1.pdf>
So, anyhow, putting that all together, I note:
people document their scientific machines and what they do
some of the properties pertain to the machine (it may measure only
these things)
there are several references to such a property already in crmsci
and dig but placed on the event.
So I wonder, for discussion, is there an interest in an instrument
class (possibly beginning a bridge between sci and dig) which would
not just be a leaf node but have its own substantial properties. I
suggest a first one might be something like 'measures
property/variable of type'.
This is not yet a proposal for such a thing, just an invitation to
discussion for those who are interested on the potential utility of
such an addition.
Best,
George
