Sorry I didn't wait for opensource.org to be up and running again. Now it works and I've read about the OSI Certification Mark and Program (http://www.opensource.org/docs/certification_mark.html). I will get the feedback from this list and then I'll contact [EMAIL PROTECTED] early next week

The QuantLib license is more similar to the MIT (http://www.opensource.org/licenses/mit-license.html) and the XNet (http://www.opensource.org/licenses/xnet.html) licenses than BSD I followed the guideline in http://www.gnu.org/philosophy/bsd.html, where FSF says: >And if you want to release a program as non-copylefted free software, >please don't use the advertising clause. [...] please copy the license >from XFree86 >[...] if you talk about ``XFree86-style licenses'', you will encourage >people to imitate XFree86 and avoid the advertising clause for certain In the same web page a few paragraphs above FSF provides a link to http://www.x.org/terms.htm from which I copied the licence. To streamline OSI approval I changed the QuantLib license so that the first 3 paragraphs are now identical to the MIT license. The updated version of the QuantLib License (http://quantlib.org/license.html) is: ----------------------------------------- QUANTLIB LICENSE 1.0 Copyright (c) 2000, 2001, 2002 QuantLib Group.

I don't know of any existing license that would be incompatible with the QuantLib license. I think that the QuantLib license won't take precedence for derivative or combined works. I look forward to your feedback ciao -- Nando -- license-discuss archive is at http://crynwr.com/cgi-bin/ezmlm-cgi?3
