License of gt6fission.pdf

[Tanimodori]

Hi Greg, I'm working on remaking my previous nuclear fission simulator and planning to add an introduction for it. I find out that Erik3003's document (https://mechaenetia.com/1.7.10/gt6fission.pdf) helps a lot in explaining the machanism and want to adapt it into my guide. So under what license that particular document was released? Is it CC0 ^ ^?

[GregoriusT]

That is a very good Question, does it say anywhere in the Document itself?

Let me ping @Erik3003

No, the document says nothing about its license. I've searched his original post, the forum, the changelog and over the Internet. The only related result I found is this post by FourierTf where he translated gt6fission.pdf and specify a "CC-BY-NC-SA 3.0" license. But I assumed that CC license was chosen arbitrarily by the translator other than the original author Erik because there's no evidence to show that Erik has ever put a license on the pdf or permitted someone to translate it. So the CC license may be invalid if Erik ends up with an incompatible license (e.g. CC-ND or proprietary ones ^ ^).

Let's wait for Erik to answer then.

With the release of .15 the document has become quite a bit outdated, I'd recommend using the ingame book for reference. Here is a link to the code of it, as that may be quite a bit easier to read: https://github.com/GregTech6/gregtech6/blob/8e4b23d0add42146c55bb280603654fa9a8f4f6a/src/main/java/gregtech/loaders/b/Loader_Books.java#L473

Since it is part of GT6, it is also covered by its license (GNU). Now that I think about it, it would probably be best if I also compile it with some formatting into a new PFD-file for the website (with a proper license this time).

The licenses that we typically used on programs and documents are different due to historical reasons. For GT6, GNU LGPLv3 appies to its code, and CC0 Public Domain for its assets (with the exception of GT logo under CC-NC). If the original gt6fission.pdf is released as a part of GT6 project as you said, it should be licensed under CC0. Is that correct? @Erik3003

[Erik3003]

That is correct, gt6fission.pdf is licensed under CC0. I also just published a new version of the document based on the ingame book also licensed under CC0 (this time from the start and not retroactively by some Github issue comment) here: https://forum.mechaenetia.com/t/rebalancing-the-fission-reactors/2177/26
