[Crm-sig] Issue 332 homework: split sample

2020-02-05 Thread Athanasios Velios

Dear all,

In the last meeting I was asked to revise the scope note for O27 split 
and provide a more specific example for it. Please consider these:


Old scope note

This property associates an instance of S2 Sample Taking with an 
instance of S13 Sample that was removed during this activity. The 
resulting S13 Sample maintains the characteristic qualities of the the 
instance of S10 Material Substantial that the sample was taken from. 
This property should be used to model cases when a homogenous sample is 
split into multiple ones.



Revised scope note

This property associates an instance of S2 Sample Taking with an 
instance of S13 Sample that was removed during this activity. The 
resulting S13 Sample maintains the characteristic qualities of the 
instance of S10 Material Substantial (i.e. the original sample) that the 
new sample was taken from. This supports reasoning that the new sample 
retains/preserves the characteristic qualities of the original sample. 
Any observations of these qualities made on the new sample also apply to 
the original one. This property should be used to model cases when a 
homogenous sample is split into multiple ones.


New example (with recommended introduction):

In 2000, Godfrey et al. [1] took a sample from a section of the tusk 
fragment GT993 which was originally found in the ship-wreck of Vergulde 
Draeck in Western Australia. This sample was homogenous (ground to fine 
powder). Part of the sample was then removed for elemental analysis 
using inductively coupled plasma atomic emission spectrometry (ICP-AES). 
Another part was removed for carbon/nitrogen analysis using a LECO analyser.


The activity (S2) of removing a part from the sample (S13), which was 
originally taken from the tusk fragment GT993 by Godfrey et al. in 2000, 
*split* the sample to create a new one (S13) for ICP-AES analysis in 
order to reveal the composition of the original sample.

[Crm-sig] Issue 332, homework

2019-10-17 Thread Athanasios Velios
This is to provide an example from conservation of the use of CRMsci 
property Oxx split [D:S2 Sample Taking, R:S13 Sample]:


---
The activity (S2 Sample Taking) of removing fibers from the sample (S13 
Sample) of Japanese Kozo hand-made paper [with dimensions 20cm×3cm], 
which was originally taken from the inside structure of a Japanese 
sliding screen and used for non-destructive spectral imaging, produced 
(Oxx split) the new sample of fibers (S13 Sample) [with sub-milimeter 
dimensions], used for destructive fiber identification.
