Greetings, I just sent in an RFP for Salomé, a very nice and highly capable engineering tool under LGPL.
It depends on OpenCascade, which has a license which sounds DFSG-free. The license is at: http://www.opencascade.org/occ/license/ There were two discussions on the OpenCascade license last year: * http://lists.debian.org/debian-legal/2006/06/msg00222.html concluded: the "In short" preamble description is not free, but the license itself is, so an upstream declaration that the preamble is not binding would make it DFSG-free. * http://lists.debian.org/debian-legal/2006/03/msg00286.html concluded that the WildMagic license is non-free, but did not conclude anything about OpenCascade. Aurelien, did you contact upstream and receive any reply on the preamble status? I don't see anything in WNPP, nor in unstable, nor in incoming. The preamble is: In short, Open CASCADE Technology Public License is LGPL-like with certain differences. You are permitted to use Open CASCADE Technology within commercial environments and you are obliged to acknowledge its use. You are also obliged to send your modifications of the original source code (if you have made any) to the Initial Developer (i.e. Open CASCADE S.A.S.). The "no private modifications without sending them upstream" part doesn't actually say that. I see it in section 4, "provided that: You document all Your Modifications, indicate the date of each such Modifications, designate the version of the Software You used, prominently include a file carrying such information with respect to the Modifications and duplicate the copyright and other proprietary notices and disclaimers attached hereto as Schedule "B" or any other notices or disclaimers attached to the Software with your Modifications. That's a pretty stringent requirement, but I'm not sure it makes it non-free. (This is what makes it more stringent than GPL/LGPL, and probably GPL-incompatible.) I think patch files in a package, or even the Debian .diff.gz file, should qualify as sufficiently describing the modifications and timestamps. A quick Google search turned up a Slashdot article claiming this is not OSD-free. But when I go to the article, a search for "Cascade" turns up nothing... Thanks for any help you can provide, and please CC me on replies. -Adam -- GPG fingerprint: D54D 1AEE B11C CE9B A02B C5DD 526F 01E8 564E E4B6 Engineering consulting with open source tools http://www.opennovation.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
