Hi Dave, Yes, there is information not contained in my message. Sorry.
In the database plugin download from RealSoftware, the MySQL plugin is shipped with the MySQL plugin source code. That source code explicitly states it is under the GPL license, not the LGPL. The contradictory part you noticed comes in under the fact that software can have as many different licenses as you wish, if you are the creator of the software. You can have multiple copies of the software. Each time you transfer the software, you can transfer it under a different license. To person A, you can transfer it under a GPL license. To person B, you can transfer it as proprietary closed source. However, once the software license is transferred, the transferee of the license is bound by the rules of the license from that point on. So, if you want to connect to MySQL databases and don't want your code to be GPL, purchase a proprietary license from the creators of MySQL, or a third party. thanks, wade Subject: Re: MySQL and RB (warning) From: David Glass <[EMAIL PROTECTED]> Date: Sat, 13 Jan 2007 13:45:05 -0800 Your message seems a bit contradictory. In one paragraph you say the MySQL plugin is licensed under the GPL, and in another you say one can purchase a non-GPL license. If it is possible to purchase a non-GPL license why would you make the jump that RS has done anything other than that? Surely they are cognizant of the licensing issues involved and would have investigated this thoroughly. Or is there information you have that is not contained within your message? Perhaps, as you imply that the Rb plugin is GPL-ed by your statement that you've asked for a non-GPL-ed plugin. On Jan 13, 2007, at 1:08 PM, Wade Maxfield wrote:
You cannot ship a product built with the MySQL plugin that RealSoftware supplies and sell your product as a commercial closed source product. You MUST distribute your source code IF you distribute with the MySQL plugin compilet into your product. You CANNOT restrict rights to re-use that source code. You CANNOT prevent someone from reselling your product or any derivations. The MySQL plugin is licensed as GPL, not as LGPL (which would allow this). I am assuming there are serious implications for RB IDE itself since it links itself with the GPL plugin, and they advertise that they include MySQL support with the product, but that is another discussion. Unless MySQL or the GPL gives them (or has given them) an exception similar to the same exception that Linus gave the Linux kernel for modules, they could have to dance in an interesting way. The general rule is if you link with a GPL product, your product is covered under the GPL. To sell a closed source product that uses MySQL, you must either go to a third party MySQL plugin that is totally GPL free, or you need to contact the MySQL folks and purchase a non-GPL license from them. They are free to have a dual license for the same product since they created the product. As creator, they can license the product different ways simultaneously.

I did give RS a feedback request for a non-GPL plugin for MySQL to RB, but they said that was MySQL's issue, not theirs. I respectfully disagree with them, but wanted to let you folks know, just in case you had not thought about it. RB's business is RB's business, but your business is yours. Please don't be caught unawares. thanks, Wade ______________________________
