To incorporate a formula to decide what to apply it to for display on
the entity pages.
This will automatically decide what number/s to choose to use to list
the release under on the entity pages (the display number).
With the new and more versatile entity / number system, we can make a
mechanism to decide what number to display / use on the entity pages.
The basic example would be the same as the current system; one catalog
number and one label, so that catalog number is used on the label page.
However, since we will have more numbers to choose from, and also more
entities to apply them to, we want a system that can choose a number
from a priority list, so there will always be a number displayed on the
release page (unless there are no numbers at all attached to the
release). So, for example, if there is no catalog number, but there is a
barcode, then the system uses the barcode on the label page
The order of priority for choosing the number to use as a label page
display / sorting / reference number is:
The following process is followed for every entity on the release:
|IF cat# = present AND cat#_description = "" OR cat#_description contains entity_name$ OR cat#_description does not contain any of the other entity_name$ entered on the release, use that cat# as the entity_name display_number and entity_name shadow_number REPEAT for each cat# entered||If there is a catalog number there, and the description is empty, the description contains the entity name, or the description doesn't contain any of the other entity names, use that catalog number|
|ELSE IF we didn't find a usable cat# for the entity, but there is a cat# or cat#s entered, use that / them anyway||If we didn't find a usable cat# for the entity, but there is a cat# entered, use that anyway|
|ELSE IF matrix# = present AND matrix#_description = "" OR matrix#_description contains entity_name$ OR matrix#_description does not contain any of the other entity_name$ entered on the release, use that matrix# as the entity_name display_number and entity_name shadow_number REPEAT for each matrix# entered||If we can't find any cat# to use, the same formula is repeated, replacing cat# with Matrix Number|
|ELSE IF... etc||repeat for Barcode, and Other Number, in that order.|
|ELSE use "none"||If we can't find anything, display 'none'|
