PDB adopts a standard Creative Commons open source license
wwPDB manages the PDB Core Archives as a public good according to the FAIR Principles. In support of the FAIR objectives, wwPDB has replaced its historical data access license with a standard open source license from Creative Commons, the CC0 1.0 Universal (CC0 1.0) Public Domain Dedication.
The new CC0 license provides the same open access as the prior license. PDB data remain freely available to all PDB Users including commercial users.
The 2021 wwPDB Charter Agreement and Usage Policy have been updated to reflect the new license.
Users of PDB data are encouraged to attribute the original authors of the PDB structure data where possible.
