A general description of the column and which data it represents (General Netadmin)

Expected format of the column

If the column is managed by netadmin, value is provided for export purposes and any change in imports will be ignored. Unlike IsReadOnly, value will be ignored on import

If the column is managed by netadmin or otherwise can never be changed. Unlike IsGenerated, value will be validated to not have changed on import. This is to avoid user confusion that the import "didn't work" when trying to change readonly values

If the column requires data

If the value of the column can be updated on an existing object.

The name of the column

Special considerations for the column or details on how it interacts with other columns. (ImpeExp specific)
