A couple of axes to consider:
- Scope of intervention:
- Inclusionary:
- In addition to existing approved subject terms, support locally-derived subject terms or terms from agreed upon alternative controlled vocabulary or classification scheme.
- Exclusionary:
- Replace existing approved subject headings with locally-derived subject terms or terms from agreed upon alternative controlled vocabulary or classification scheme.
- Hybrid: Leave existing approved subject headings in place, but supress them from display while adding locally-derived subject terms or terms from agreed upon alternative controlled vocabulary or classification scheme.
- Level of intervention:
- In Alma:
- Are we doing something in the network zone or the Institutional zone?
- Are we doing something
- In Primo:
- A simple transformation doesn't account for the nuancing.
