Add a CC0-1.0 term to the license for notify-types #661
Conversation
Also copy in the LICENSE-CC0 file. This reflects the fact that src/events.rs was moved from the existing notify crate in 08e74da.

I don't think this comment is necessary.

I’m happy to remove it.

MIT OR Apache-2.0 OR CC0-1.0 would be less restrictive and still correct.

To me, MIT OR Apache-2.0 OR CC0-1.0 is inaccurate, because it implies the entire crate may be used under any of those licenses. Most of the crate may be used only under MIT OR Apache-2.0, except that src/events.rs may be used only under CC0-1.0. So usage of the entire crate must satisfy both (MIT OR Apache-2.0) and CC0-1.0 – not either.

The header of src/events.rs should be updated as well, then. I didn't update it when I moved the code, but that was not intentional. The notify crate is licensed under CC0-1.0 only for historic reasons. The newer crates are all MIT OR Apache-2.0.

Do you mean that you are able to relicense src/events.rs to match the rest of the new notify-types crate, even though it originated in and was moved from the types crate? That would certainly simply matters, if true – all that would be needed would be to adjust the header in src/events.rs, and notify-types/Cargo.toml could be left unchanged.

Yes, we should re-license src/events.rs. I would still add CC0-1.0 to notify-types/Cargo.toml while we are at it, so people can use notify with just the CC0-1.0 license. Technically also a re-license, but notify-types contains only data structures anyway...

I'm not sure changing MIT OR Apache-2.0 to MIT OR Apache-2.0 OR CC0-1.0 is a good idea? CC0-1.0 is originally intended for "content" and not code, and it's not really considered a suitable license for code any longer. However, if you think that the src/events.rs file can be relicensed / the license header removed to align it with the rest of the crate, that would be great. As you said, the crate contains almost exclusively definitions of data structure / interface definitions.

I don't have a strong opinion, one or the other way. I just noticed that before moving the types into a separate crate, people could use notify with just agreeing to CC0-1. So I thought we could restore that. But I doubt agreeing to MIT or Apache-2.0 on top of CC0-1.0 will be an issue for anybody.
This file was copied from the main notify crate and had a header comment that indicated it was licensed CC0-1.0 or Artistic-2.0 with an additional clause (see notify-rs#514); Since @dfaust indicates in notify-rs#661 (comment) that this file can be relicensed, we simply remove the old header comment to indicate that (by default) it falls under the overall (MIT OR Apache-2.0) license of the notify-types crate.

Based on the discussion in this PR, and to avoid conflating different goals, I’ve reframed this in a new PR #662 that focuses on relicensing |
This changes the license of the notify-types crate from MIT OR Apache-2.0 to MIT OR Apache-2.0 OR CC0-1.0 and adds a copy of LICENSE-CC0 from the main notify crate, as requested in notify-rs#661 (comment).
