After reading quite a bit on licensing of datasets, and some initial hesitations, all the data here is now clearly licensed as Creative Commons CC0 License (Q38) (see List of references on data licenses (Q2008) for some of the references that informed our thinking).
If not explicitly stated, no license is granted on the software hosted here. This is most likely due to omission, but possibly more strategic. We would love to have a deeper conversation with you on those topics. Please do reach out.
