[Eeglablist] Changing the EEGLAB open source license

Hi Arnaud

I have no feelings about how you want to manage licence within EEGLAB, what I'd like to raise here is license compatibility with plug-ins. I do know that it can conflict, but do not know how this works. For instance, I do want to keep GPL GNU for LIMO EEG. This allows commercial use but only using open software. How is this compatible with the core as DSB. Sounds to me it just fine since as a toolbox but less if we distribute it as core with the new study frame (don't have too). Same for other toolboxes .. just double check

Subject: Changing the EEGLAB open source license

Dear list,

As developers for the UCSD copyright holder, we can change licensing terms of new EEGLAB releases. We are now contemplating changing the EEGLAB core code license for future versions from a GNU GPL to a BSD open source license, which is more permissive and allows broader usage. Our sponsor the U.S. National Institutes of Health recommends that the terms of software availability permit the commercialization of enhanced or customized versions of the software, or incorporation of the software or pieces of it into other software packages — these are not possible under the GNU-GPL license.

Below is a link to an article on open licenses for scientific software. We would like to receive any comments or recommandations. Note that this move is an attempt to comply to NIH guidelines and to increase dissemination of advanced methods for analysis of electrophysiological data. It does not mean that we plan to commercialize EEGLAB in the foreseeable future.

Of course, earlier versions of EEGLAB will remain available under their original licence. And EEGLAB plug-in extensions can be released under their own licence of choice.

Best wishes,

Arno & Scott
