The Record vs. Record's Arrangement
-
What is a Record?
-
Is an Item a Record?
-
Is a Piece a Record?
-
Is a Piece a Record when it has Item(s), or is it then a unit of Arrangement?
-
-
What about:
-
Sub-sub-series?
-
Sub-series?
-
Series?
-
Division?
-
Department?
-
-
ICA RiC says: RecordSet, Record, and RecordPart

Inheritance
-
Some (Meta)Data Elements are inherited downwards
-
Specification - in TNA-CS13
-
Implementation - Normalisation in ILDB
-
-
e.g. Immediate Source of Acquisition (ISoA)
-
May be expressed at levels: Department, Division, Series, Sub-series, Sub-subseries, Piece
-
Presentation: Start at level n, work upwards (n-1) until an entry for a level is found.
-
Example, Item:
AIR 28 2904/1
-
Department ISoA: "
from 1960
" -
Series ISoA: "
, from 1974
" -
NOTE: for presentation/understanding, Series level is used as it is the lowest-level
(i.e. closest to the Item)

Are these properties about the Record or the Record Set?
