[Haskell-cafe] Dual-licensing the package on Hackage

2013-07-30 Thread David Sorokin
Hi, Cafe! Probably, it was asked before but I could not find an answer with help of Google. I have a library which is hosted on Hackage. The library is licensed under BSD3. It is a very specialized library for a small target group. Now I'm going to relicense it and release a new version

Thanks Thu, I agree with you. Just I don't know what to write in the license field of the .cabal file: GPL or OtherLicense. The both choices seem correct to me and misleading at the same time. Cheers, David 30.07.2013, в 12:53, Vo Minh Thu написал(а): 2013/7/30 David Sorokin

Well, if you are willing to grant me a GPL license when I download your package through Hackage, GPL is accurate. Again you are not providing me with another license. Obtaining a commercial license should be seeked through other means, perhaps by sending you an email. I don't think Hackage should

Perhaps it would be best if .cabal allowed to have more than one license listed. Another solution would be to use custom field, for example: License: GPL x-Other-License: Commercial, see License-Commercial.txt All best, Krzysztof Skrzętnicki On Tue, Jul 30, 2013 at 11:44 AM, David Sorokin

Unless you want to provide multiple open source licenses, I don't see the point: Anybody that needs a commercial license (and has some money) will simply ask for such a commercial license when seeing that the code is available under GPL. Another reason it is pointless is that you will certainly

I am inclined to use value OtherLicense but state in the description that the package is available either under GPL or a commercial license. The latter must be requested to me. Then there would be no required additional steps to use the package under GPL. Only the LICENSE file must be

Again I haven't seen a reason to do what you propose: virtually every single GPL library author would gladly accept money for their work to be used in a closed source setting, no need to use OtherLicense to reach that effect. On the other hand, you will stop people interested in open source to

One question is how much of a discovery/indexing role Hackage plays. There can be a tremendous difference in ease of obtaining a commercial license, and a restriction for things I can use in a proprietary project, once I pay enough seems like a legitimate use case. It also has some bearing on
