[API] Request for endpoint: obtaining functions and their translations

[rinkp]

What would you like?

An API endpoint that would return approximately the following:

{
   "functions":{
      "Lid":{
         "nl":"Lid",
         "en":"Member"
      },
      "Voorzitter":{
         "nl":"Voorzitter",
         "en":"Chair"
      }
   }
}

A read-only endpoint will suffice for use cases that currently can be envisioned, and separate permission should be introduced for accessing the endpoint.

Why is this needed?

The association needs one authoritative source of organ functions and their translations, which then can be used in other systems as well. Since GEWISDB will contain all decisions regarding installations in functions, GEWISDB is the ideal candidate for being this authoritative source. For the Active Directory sync, it is desired to use the English translation of function titles in group names, whereas decisions are made in Dutch
