As explained in the GPL: "The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users." The ODbL falls into the former category of "licenses". The ODbL *is* somewhat more similar to the GPL than it is to CC-BY-SA. But CC-BY-SA was chosen as the license for OSM, not the GPL. So stop saying the ODbL is in the same spirit as CC-BY-SA. Claim it's in the same spirit as the GPL, and then we can have that discussion. > requirements go beyond requiring derivative works to be licensed under the > > same license.

If you'd like me to compare the ODbL to the GPL, please start a new thread, and I'll be happy to make the full comparison. I hope you first realize, though, that CC-BY-SA is not the GPL. CC-BY-SA does not require you to distribute source code when you distribute binaries. It is not *intended* to require that. And anyone who takes the time to read the simple one page description of CC-BY-SA ought to know that.

There's little chance I'm going to release my software under the BSD license.

Ain't it grand having lawyers make laws? :) > Actually, I've decided I'm not going to release my data as PD. I prefer copyleft. I prefer CC-BY-SA. It keeps people from taking my data and incorporating it into data under more restrictive licenses. Like ODbL.
