all DOI?Hey, when I try to download the Q-IDs of all DOI registered to Wikidata I always run into timeout. I tried to limit the amount of itmes by reducing the scope to scholarly articles. Is there a way specify for example to small chuncks of items (maybe only Q-ID registered from 2010-2011) that could be combined later on? Thank you!
