Recent changes to the author categories introduced author identifiers, which were key data names. However, legacy data files will not have this data name and thus fail validation. The current changes introduce dREL methods that provide default values.

Although we can generate arbitrary ids for parent categories publ_author and audit_author where they are missing, we cannot do the same for their child categories. This commit adds dREL that searches for matching names in the parent categories and determines the missing identifier accordingly.

Missing identifiers can now be generated by dREL using the Unique_id function.
