Currently in GSIM it seems you can only build 'flat' Category Sets and Code Lists - the only time a hierarchy is introduced is through the inclusion of Level in a Classification Item for Classification Schemes.
Some thoughts for discussion:
- Should it be possible to create a Hierarchical Code List (ie, a code list with a hierarchy that is not a classification scheme), or a Category Set (a hierarchical set of Categories that have not been enumerated by Codes)?
- Are the current definitions of Category Set and Code List broad enough to allow for the possibility of a hierarchical set?
- Should Category Set and Code List also include a relationship with Level? (Allowing for the building of hierarchical set)
