At least I have heard that description: > > http://www.edwardbear.org/serendipity/archives/1193_My_Beef_with_MySQLs_Lice nse.html That is a very strange definition of derivative work. What makes MySQL different in this regard than, say, Windows? If a database is primarily a platform for development, and this test were to be held up wouldn't that make a wide variety of applications derivative works of MS Windows? Quickbooks come to mind. IMO (and IANAL), this is one of the real problems with the GPL. Due to the lack of guidance from the courts, developers can say who they will or won't sue regarding derivative works, but there is prescious little one can say about the outcome in advance except in the most clear cut cases. There was an article on Groklaw recently regarding a legal overview of open source, and derivative words were discussed. The reason why I think that this is relavent is that it means that MySQL is not really 'open' in the way that the Linux kernel or PostgreSQL is-- namely that it uses the GPL to deliberately break accessibility to proprietary applications which everyone else considers to be separate works. This leads a MySQL developer into a bad situation where they are forced to choose between litigation or licensing (even if they are within their legal rights, IMO). This seems to be a point we could make. Maybe a paper on the advocacy site: What you should know about MySQL. Best WIshes, CHris Travers
