Licence

When I created my first dataset on Hugging Face, I had to choose a license. There were so many options that I got confused, so I tried to figure out which license type is most appropriate for my dataset.

GNU's Not Unix! (GNU)

GNU is a free, copyleft licence that allows to share and change all versions of a program--to make sure it remains free software for all its users. The General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.  There are GNU's licence families:

• GNU General Public License is is used by most GNU programs, and by more than half of all free software packages

• GNU Affero General Public License is based on the GNU GPL, but has an additional term to allow users who interact with the licensed software over a network to receive the source for that program

• GNU Lesser General Public License is used by a few (not by any means all) GNU libraries.

• GNU Free Documentation License is a form of copyleft intended for use on a manual, textbook or other document to assure everyone the effective freedom to copy and redistribute it, with or without modifications, either commercially or non-commercially.
