Proposed change of license to LGPL

[Pavel Solin]

Hello,

  there is a lot of interest in changing femhub-distribution license 

from GPL to a bit more permissive LGPL. Please let me know 

if you have any objections against this.

Best,

Pavel

Hi Pavel,

Could you briefly describe the consequences?

For example, a commercial software could link femhub-distribution

without having to be open sourced. This is not possible with GPL.

A prerequisite of course is that all packages in femhub-distribution 

that would be linked are LGPL or more permissive.

A natural solution to this problem would be to only accept to 

femhub-distribution packages that are LGPL or more permissive.

I was thinking about Hermes. What would happen there?

Anyone could take the library and link it to their code (non-profit 

or commercial). But they would not be able to change it.

Would they be obligued to acknowledge Hermes's use?

Preferably in the way we prescribe (mentioning Online Lab & Agros for
marketing reasons)?

No. If they use Hermes, they are not obliged to acknowledge 

other packages.

plasm is already LGPL 

2 years ago, we made the same change.

best,

Dear Alberto,

  the LICENSE file to Plasm says:

This software is licensed under the terms of the GPL, due to the Juce library.

Regarding FEMhub-distribution we will have to be a bit careful 

since various packages have various licenses. We should not 

be putting one overall license on the entire distribution, which 

also means that we should not be distributing femhub-distribution 

as a single binary package anymore. The build system etc. (our 

codes) can be LGPL. I think that each user should download and 

install any femhub package he/she wants, and deal with its license 

individually.

Best,

Pavel

Dear Pavel,

I have a bad memory.  Of course you are right.  

We discussed the problem, and agreed to put the Plasm  license in LGPL form, but we needed

to buy a commercial license to Juice, and to include it in binary form.

Actually, we never implemented the decision and I even disremembered the whole discussion.

So, we are going to buy the full version of Juice commercial license (with right of sub-licence.) asap.

Thanks for pointing out the problem!

Best,

Alberto

This would be really awesome. Currently, GPL packages make us 

use GPL for the entire FEMhub-distribution. This will change. 

FEMhub-distribution as a framework will be LGPL, and all LGPL

packages will stay among default packages. Packages with less

permissive licenses a user will have to download and install into 

FEMhub separately, and he/she will deal with the license on his/her 

own.

 

Thanks for pointing out the problem!

Thank you very much and best regards,

Pavel
