4. Good licensing and copyright practice: the practice

Here's how to translate the theory above into practice:

4.1. Make yourself or the FSF the copyright holder

In some cases, if you have a sponsoring organization behind you with lawyers, you might wish to give copyright to that organization.

4.2. Use a license conformant to the Open Source Definition

The Open Source Definition is the community gold standard for licenses. The OSD is not a license itself; rather, it defines a minimum set of rights that a license must guarantee in order to be considered an open-source license. The OSD, and supporting materials, may be found at the web site of the Open Source Initiative.

4.3. Don't write your own license if you can possibly avoid it.

The widely-known OSD-conformant licenses have well-established interpretive traditions. Developers (and, to the extent they care, users) know what they imply, and have a reasonable take on the risks and tradeoffs they involve. Therefore, use one of the standard licenses carried on the OSI site if at all possible.

If you must write your own license, be sure to have it certified by OSI. This will avoid a lot of argument and overhead. Unless you've been through it, you have no idea how nasty a licensing flamewar can get; people become passionate because the licenses are regarded as almost-sacred covenants touching the core values of the open-source community.

Furthermore, the presence of an established interpretive tradition may prove important if your license is ever tested in court. At time of writing (early 2001) there is no case law either supporting or invalidating any open-source license. However, it is a legal doctrine (at least in the U.S., and probably in other common-law countries such as England and the rest of the British Commonwealth) that courts are supposed to interpret licenses and contracts according to the expectations and practices of the community in which they originated.
