Developer Certificate of Origin

Noun · Open Source

Definitions

  1. A lightweight contribution attestation, commonly abbreviated DCO, where contributors certify that they have the right to submit the code and agree to the project’s contribution terms, usually via a signed-off commit. It is often used instead of a separate CLA workflow.

    In plain English: A standard way for contributors to confirm they are allowed to submit the code they are providing.

    Example: "The patch couldn’t merge until the author added the signed-off-by line required by the Developer Certificate of Origin."
