My understanding is that we're waiting for AT to reply. If that's not correct and the submission is ready to be published again, please let us know.
Thanks for the patience!
Thanks for the submission. I find some information confusing.
As part of the OGA moderation team I disabled downloading until licensing/authorship is clear
There are files that you created and files that you did not create?
Are there files that are remixes of files by others?
I would assume the screenshot contains art by many people but licensing and authorship needs to be clear for all files in a submission, as well as previews.
the licensing choice is not for stating "there are files under A but also files under B license" but for stating "all files are dual-licensed under A and B licenses".
I recommend replacing this submission with a zip and preview that contains only CC0 works only made by you (yd) and uploading the pack to the AT forums.
I recommend zips for files and a preview that contains all sounds.
montage-sfx from https://github.com/qubodup/ogatools can help with that.
Just in case a note: Licensing your work under CC-BY-SA does not mean that you can not license it under other terms as well.
You can allow use under proprietary terms. This would allow one additional specific use, but it could not be shared with others, meaning you control the people who can use your work without having to follow free license restrictions and you can even limit the scope (only one project - a term that might require definition in the agreement though).
For example such a license could state something like "TEAMNAME may use my work for PROJECTNAME and may not re-distribute my work to others, except as part of PROJECTNAME. TEAMNAME may not sublicense my work. TEAMNAME may not use my work for any other purpose. TEAMNAME specifically may use screenshots and videos of PROJECTNAME, in which my work is displayed for marketing purposes." - something like that. Note that I have hardly any experience with proprietary licenses though and this example might have loopholes and be incomplete.
I recommend that you demand compensation in return for using your work under non-free terms. If you don't care for the money it, you can ask that they donate for a cause you approve of, for example in my case I would ask for donations to OGA or Freesound or perhaps CC.
Thanks for letting us know.
The art license of 0 A.D. is CC-BY-SA 3.0
https://github.com/0ad/0ad/blob/master/LICENSE.txt (it says there are further license text files in the art asset directories)
This appears to be a common practice HTML5. The biggest advantage is less files to download, I'd say.
This got discussed in a HTML5 game dev podcast that I recommend:
Hi and thanks for asking,
CGtextures' works and derivatives are prohibited from being freely licensed (cc-by, cc0, cc-by-sa, gpl) but only freely licensed works are permitted on opengameart. Therefore CGtextures' works can't be used in works submitted to opengameart.
Hope this clarifies it.
Is there any reason to prefer .tga over .png? I would expect png to be wider spread and easier to load than tga. Tga seems to have the disadvantage for downloaders, that compression is optional (as far as I know, compression is mandatory in png).
I have a tutorial for that as well actually ^^
My recommendation is indeed to use the username and ideally link to their user page.
http://creativecommons.org/licenses/by/3.0/legalcode Sections 4.a./4.b. specify what attribution requirements exist by default.
Please attribute "Iwan 'qubodup' Gabovitch" or "Iwan Gabovitch" if it doesn't fit the style/width of the remaining credits. If possible, make it link to http://qubodup.net or http://freesound.org/people/qubodup/. Not required in this case though.
CC-BY requires attribution, in case you didn't know and were using other sounds under that license.
Thanks! I hope these are useful and good luck with the release.
