Not to mention that MARC lists often include all four of these:
- Other
- Unknown
- Not applicable
- No attempt to code
I argued before the MARC standards group that anyone who was not
attempting to code the data element in question would also NOT be
likely to code "No attempt to code"... oh, well.
Back to the lists: there are a number of "lists" that aren't really
lists in RDA:
7.17.2.3 R Recording Colour of Still Images
If the still image or images contained in the resource are in black
and white or shades of grey, record black and white.
If the image or images in black and white are tinted and/or toned,
specify tinted, toned, or tinted and toned as appropriate, in
parentheses, following black and white.
If the image or images are in sepia, record sepia.
If the image or images in the resource are in one or two colours, name
the colour or colours.
Yet RDA considers this a controlled list, and there are different such
lists for different materials: RDA colour (still images), RDA colour
(moving images), RDA colour (three-dimensional forms) (and there may
be others). The lists are included in the RDA element analysis table
as vocabulary encoding schemes. So we have lists that don't have a set
of values, but in addition we have these lists whose values (if we had
them) would overlap
The MARC record has actual vocabulary lists for colour for different
materials, and these are not open-ended (well, except for 'other'). So
for projected material MARC has:
One color
Black-and-white
Multicolored
Hand colored
Mixed
and for electronic material:
One color
Black-and-white
Multicolored
Gray scale
Mixed
IF there were actual lists in RDA, it might be possible to create a
master list and use the application profile concept to create
format-specific lists. But there aren't really lists in RDA...
