Thoughts on copyrights, but ....
Good question Jim,
I would recommend using a license which meets the free cultural works definition. There are two mainstream licenses which meet this requirement:
- CC-BY -- The license which grants the most permissions on condition that the original author is attribute. Under this license it is possible for derivative works to be published under an all rights reserved license in the case of a commercial publication.
- CC-BY-SA -- The sharealike license requires that all derivative works must be released under the same license (hence sharealike). This is often called the viral clause because all derivative works must contain the SA provision. If you're concerned with commercial exploitation of your work -- This is a good way to protect your work.
There is also a No rights reserved tool:
- CC0 is a mechanism to achieve the effect of a public domain declaration especially in countries where the public domain is not recognised. With CCO waive all copyrights and related or neighboring rights that you have over your work, including for example the requirement for attribution. It is therefore a no rights reserved tool.
