Hi,
I want to store the same data but at different points in time. How can I do it?
For example:
Time: 3/23 10:00
A 10
B 20
C 30
and then next time:
Time: 3/23 10:10
A 15
B 25
C 35
I want to keep the two data simultaneously and then I can calculate the difference between them.
Thanks very much
stephen

You can represent a set of measurements at a specific time as its own entity and each measurement as an edge off of it:
:Measurement20200323T1000 a :Measurement ;
:takenAt "2020-03-23T10:00:00Z"^^xsd:dateTime ;
:aValue 10 ;
:bValue 20 ;
:cValue 30 .
:Measurement20200323T1010 a :Measurement ;
:takenAt "2020-03-23T10:10:00Z"^^xsd:dateTime ;
:aValue 15 ;
:bValue 25 ;
:cValue 35 .
Hi stephen,
Okay, I got it.
Thank you.
