Thank you for the plug for https://clearlydefined.io !
For those who did not hear about this, ClearlyDefined is a project
that incubates at the OSI. So that would be quite a natural source of
licensing data. There are about 20 million versions of open source
packages that have been scanned with scancode-toolkit there and this
contains all OSI-approved licenses and many more.
This is of course a biased subset and yes, it may not cover everything
out there yet. But this is likely the biggest and most comprehensive
license-related data set available today.
