could anyone propose University of California workers to change bvls license?
hi all, here's a fortran routine bvls, free for non-commercial purposes: http://lib.stat.cmu.edu/general/bvls Could anyone contact to the authors of the routine and propose them make it available in terms of GPL/LGPL or, moreover, BSD license? I have already working Python interface (via f2py, thanks to Pearu Peterson for assist), so, if BSD - it could be connected to scipy. In anyway, this routine would be of great interest in scikits.openopt users, because solvers ralg and lincher could be enhanced (in case of >1 constraints), and, of course, mere bvls solver could be included to LLSP class. Authors of the routine, as it is mentioned in the file header, are Robert L. Parker Philip B. Stark Scripps Institution of Oceanography Department of Statistics University of California, San Diego University of California La Jolla CA 92093 Berkeley CA 94720-3860 rlparker@ucsd.edu stark@stat.berkeley.edu I would contact the authors of the routine by myself, but IIRC some scipy developers work in this university and have better English language knowledge. Regards, D.

I used to work there, but I really doubt that they will consider a change of license. They really do want to restrict its use to non-commercial purposes. Or rather, the Technology Transfer Department of UCSD does. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco

I asked Stark and Parker, and they agreed to release under GPL. I have asked them to specify the GPL version number. I also asked them to consider the LGPL, but I cannot say whether they will. Cheers, Alan Isaac

OK, here is the situation. It turns out that BVLS was previously released under GPL v.2 to the R project. The authors are happy to have it available under that license. However, they also appear willing to consider LGPL and possibly BSD if that would be helpful. I would need to be able to tell them how it would be helpful. Could someone better versed in SciPy/licenses interactions help here? This is what I think. GPL code can be used in SciKits but not in SciPy proper. If so, is it desirable/important that this code be available in SciPy proper? Finally, one author added the following statement: "I would be happy to license it under anything that keeps attribution to Bob and me and that keeps the code intact." I do not really know what this means. The GPL itself makes no commitment to keep the code "intact", right? Can I address this concern in any way? Thank you, Alan Isaac

Sure. Even if it is just used in OpenOpt, OpenOpt would also benefit from it being BSD-licensed.

You will have to ask them exactly what they mean by that. Inform them that both the GPL and BSD licenses require attribution, but both also allow licensees to distribute modified code. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
