@mcc I’ve heard of one other, but it’s Not Good™.
CC is great, but all codes are bad unless they’re actually enforced
@mcc the homepage has some resources: https://www.contributor-covenant.org under “Before You Adopt Contributor Covenant”
I personally don’t have experience using a code of conduct in OSS
@mcc There were a few, but it seems like they've mostly dropped off. If you don't have an existing community, just adopting CC is a good starting place. Otherwise, it's a much better idea to take parts you like from many projects codes of conduct to create something that works for everyone. Simply adopting an off-the-shelf code of conduct can create more conflict.
https://github.com/todogroup/opencodeofconduct and https://web.archive.org/web/20180707014644/http://citizencodeofconduct.org/ are two of the more well-known OTS attempts.
@mcc not a code of conduct itself, but @sunnydeveloper's work on CoC enforcement is incredibly important and worth a look!
(from an open source perspective)
Ubuntu CoC used to be quite popular. It was one of the first major projects adopting a CoC. But it really shows its age, with the large focus on "meritocracy". Nevertheless, many others, such as the Django one, have taken inspiration from it.
Another one is the Citizen CoC: https://web.archive.org/web/20200330154000/http://citizencodeofconduct.org/
Imo, enforcement is much more important than what's actually in it. For example, Ubuntu Discourse is a great place thanks to the mods, not the CoC itself.
