Abstract
The Oupoco Database is a collection of 4,872 French sonnets developed in the framework of the Oupoco Project. It is mainly composed of poems from the 19th and early 20th century. The sonnets come from different sources from the Internet and from a collaboration with the Bibliothèque nationale de France. Every sonnet has a specific license (depending on the source it comes from), but the whole collection can be reused for free (under the Creative Commons Attribution 4.0 International license).
