BindingDB is listed as a FAIRsharing resource (), and data curated by BindingDB are shared under the Creative Commons Attribution 4.0 License (CC BY 4.0). This allows both noncommercial and commercial reuse and redistribution, subject only to citation of BindingDB and notation of any changes made to the data. Data curated by ChEMBL, which is also a FAIRsharing resource, are shared under the Creative Commons Attribution-ShareAlike 3.0 license (, accessed 7/3/2024). This adds the requirement that any reused ChEMBL data must be redistributed under the same license. Thus, ChEMBL data in BindingDB are subject to the ChEMBL license, and they are marked as curated by ChEMBL to enable compliance. In contrast, the user license for PDBBind forbids redistribution without explicit permission as of this writing (), and we do not collect the PDBBind dataset. The BindingDB webpages provide documentation of the formats of our downloads (e.g., tab-separated value files and SDfiles), and of the webservices provided.
