Authorities

It is possible to provide authority sources for vocabularies. Configuration:

VOCABULARY_TYPE_METADATA = {
    "funding": {    # vocabulary of funding
        "name": {
            "en": "Funding"
        },
        "authority": FundingService
    }
}

where:

from oarepo_vocabularies.authorities import AuthorityService

class FundingService(AuthorityService):
    def search(self, query=None, page=1, size=10, **kwargs):
        # performs an API and returns a listing 
        # of serialized vocabulary items, for example:
        return {
            'hits': {
                'total': 2,
                'hits': [
                    {"id": "03zsq2967", "title": {"en": "Funding 1"}},
                    {"id": "a4gfhtt56", "title": {"en": "Funding 2"}}
                ]
            },
            # optional pagination links here
        }
    def get(self, item_id, *, uow, value, **kwargs):
        # performs lookup by id and returns vocabulary metadata
        
        # in this example:
        return next(x for x in self.search()['hits']['hits'] if x['id'] == item_id)

Ordering

This extension supports ordering and suggestion in different languages. It is enabled by default and enables all languages in I18N_LANGUAGES, BABEL_DEFAULT_LOCALE. Sorting by title sorts by the title in the current language, suggestion suggests in id and title in the default language.
