We think GPL makes sense here, as we like to make profit everybody from improvements in the main software.

You can build your own Plug-Ins which you don't need to GPL.

Glad you visited, good bye. (-,

> You can build your own Plug-Ins which you don't need to GPL. This is incorrect. In general to allow non FOSS plugins you need to use the LGPL instead. If this is something you care about you might consider licensing the main app/plugin in system under the LGPL and the plugins you provide under the GPL.

[loomi]

Hm we like it more the other way around. That the application and from us provided Plug-Ins are GPL and people are free to license there Plug-Ins as they please.

Anyway we will for sure not do any legal actions against Plug-In developers.

[alexchamberlain]

Does the licence need to be copy-left for that?

[loomi]

Sorry I don't get you, can you rephrase please. It is open source and hence copy-left .. ?

[alexchamberlain]

Something can be open source, yet not copy-left. For example, the MIT licence allows commercial usage and modification.

[loomi]

True, in this case we decided to have GPL because we love to also get back new developments on ImagePlay for our students.

On the other hand we are open regarding Plug-Ins.

I hope this makes sense? At the end we are not specialist on the legal end of things.

[alexchamberlain]

Personally, I think it's a shame. GPL generally puts me off as the licence is too complex for me to understand and I don't understand in what situations I can and cannot use it. MIT, BSD etc are simple enough that even without a legal brain I can get the gist of what I can and cannot do.

[belorn]

If I take the MIT license and add a single word, and it would make it incompatible with every other license out there.

You can't make "profit" when your "customers" make no profit. Poor people barely donate a lot.

[loomi]

Okay, but at the end this is not too much about profit.

More to give teachers in the world a tool for teaching Image Processing in a more intuitive way. They anyway will not make profit I guess with ImagePlay.

But if you find someone willing to "donate" enough we might switch license (-,
