The Federation of Finnish Learned Societies is working on a global registry of learned societies and want that as a type in ROR. In addition, some OA management intermediaries (ChronosHub, OA Switchboard) might benefit from a "Publisher" organization type.

Adding values such as "Learned Society" and "Publisher" (or similar) to the list of valid org types in ROR

Who would benefit from this change?
OA deal management services, scholarly societies, FFLS
