Hello,
we have a problem since the last update with the API. We update our database online with the api, so we use the call:

$url = "https://api.zotero.org/groups/{$zotero_group_id}/items/?key={$zotero_key}&format=rdf_zotero&limit=100&start={$i}";

since the last update of zotero, this call will not provide the same data as before, as an example we are missing too many fields, like "title", "language", ...etc.


this an old version of a response:
