Use case
Please see the attached picture for a graphical representation of the use case.

REST API changes

Currently a REST API call to get the entries for a controlled vocabulary or a form-value-pair look like this:

Get entries for a controlled vocabulary: host/api/integration/authorities/srsc/entries?query=&metadata=dc.subject&uuid=a7fd0586-c098-4b2e-966b-c6b13fc8e96a&page=0&size=100

Get entries for a form-value-pair: host/api/integration/authorities/common_types/entries?query=&metadata=dc.type&uuid=a7fd0586-c098-4b2e-966b-c6b13fc8e96a&page=0&size=100

In order to get language-specific vocabularies or form-value-Pairs the Angular client should use the Accept-Language header (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language).

A REST API call to fetch language-specific form-value-pairs or controlled vocabularies may look like this:
REST API calls to get a controlled vocabulary in German: host/api/integration/authorities/srsc/entries?query=&metadata=dc.subject&uuid=a7fd0586-c098-4b2e-966b-c6b13fc8e96a&page=0&size=100&Accept-Language=de
REST API call to get a form-value-pair in German: host/api/integration/authorities/common_types/entries?query=&metadata=dc.type&uuid=a7fd0586-c098-4b2e-966b-c6b13fc8e96a&page=0&size=100&Accept-Language=de

First (naïve) approach on what has to be changed at the backend:
Add a new language attribute to form-value-pairs and controlled vocabularies. Allow two or more form-value-pairs or controlled vocabularies to have the same name attribute. If two or more form-value-pairs or controlled vocabulary have the same name attribute make sure they have different language attributes.

Flagging as "More Details Needed", simply because it requires more discussion before this feature can be scheduled for development/release.
