Wikidata and other identifiers

Almost all the objects in our data are aligned with a wikidata id. It is the case for authors, keywords and cities. The wikidata id can be found in the field alternative_urns.

Let us look for an author:

meleager = requests.get('https://anthologiagraeca.org/api/authors/1').json()
