A novel feature in COCONUT 2.0 is largely automated data submission and curation. Users can submit structures and metadata to COCONUT that have been newly reported in the scientific literature or have not yet been included in the database. We provide a CSV format template for bulk submission of multiple data additions or updates. These will be automatically parsed, standardised, and included in COCONUT after approval by the curators. Data curation can also be performed through tickets created from the pages of individual compounds, where users can flag compounds needing curation or suggest concrete changes to a compound's entry. A specific use case we envision is that of users reporting structures in the database that they would not classify as natural products but rather as synthetic compounds. Since most studied organisms in the Anthropocene come into contact with synthetic chemicals almost everywhere every time, these regularly appear in natural product databases as well. This reporting feature requires users to provide evidence to support their claims. Submitted reports are internally validated by curators on the platform (internal and community), and the data is updated accordingly. Updates are audited, and the complete history of the data changes (who, what, and when) is accessible on the compound details page. Furthermore, a link to COCONUT's GitHub issue tracker is prominently displayed at the border of every COCONUT page, allowing users to submit reports on bugs or make feature requests.
