Libra Data Community Norms

CC0 Waiver for Datasets

By default, all datasets added into Libra Data are granted the CC0 Public Domain Dedication. Libra Data uses the CC0 waiver by default for all datasets (4.0 and on) because of its name recognition in the scientific community, making it a familiar option for data (for which in general copyright does not apply), and is in use by repositories as well as scientific journals that require the deposit of open data. For more information on the CC0 waiver, please visit the Creative Commons website ( Data depositors can opt-out of using the CC0 waiver for their datasets, if needed.

Libra Data asks that all users who download datasets from Libra Data’s services follow the following Community Norms.*
