The multilingual DraCor platform (https://www.dracor.org) represents a valuable resource for literature and theatre scholars, allowing them to host, access and analyse thousands of plays from Antiquity to the XX century. After briefly presenting the workflow for the ingestion of new plays into our ecosystem, we focus on the collaborative side of our endeavours, demonstrating how external scholars can benefit from a range of tools and guides to easily prepare and submit their own collections. As a showcase of the process, we present three corpora currently in production, focusing respectively on Ukrainian, Czech, and Early Modern English literature.
