What licenses should we offer for copycan ? According to the gnu, there are four freedoms : * The freedom to run the program, for any purpose (freedom 0). * The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this. * The freedom to redistribute copies so you can help your neighbor (freedom 2). * The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this. For content it means in my understanding: * You can use the content * You can modify the content * You can share the content * You can share the modified content Now if I give content to you under a license allowing these four freedoms, do I require you to share under the same conditions or not? Also, should it apply do all form of derivative works? GPL does respect those freedoms, requires you to pass on the freedoms, and applies to derivate works. Public domains also respects those freedoms, but does not require you to pass on (and therefore does not care about derivative works) What would be best to do? ------------------------------------------------------------------------ Ok, while listening to Lessig on cc at the WOS4, it seems to me that my license would look like this: With this content you have to follow the following rights and obligations (rules): 1. You can use the content 2. You can modify the content 3. You can share the content 4. You can share the modified content 5. When passed on the full meaning of the 7 rules have to apply to the received content 6. The 7 rules expand to all content this content is included in 7. The 7 rules are set irrevocably
